Shock absorber performance testing and maintenance work

Automobile shock absorber is used in the process of wearing parts,exhaust manifold manufacturer shock absorbers work is good or bad, will directly affect the stability and other parts of the life of cars, so we should make the shock absorbers are often in good working condition.

 The following methods can test the shock absorbers work is good. 1 so that cars on the road in poor condition after driving 10km road parking, touch shell shock absorber, if not hot enough, indicating no resistance inside the shock absorber, shock absorbers do not work. At this point, you can add the appropriate oil, then test, if the housing fever, shock absorbers, compared with an internal oil, should add enough oil; otherwise, indicating shock absorber failure. 2 Press firmly on the bumper, and then release, if the car has 2 to 3 times jump, then the shock absorbers work well.

 3 When the car slowly driving and emergency braking, if the car more violent vibration, indicating a problem with the shock absorber. 4 Remove the shock absorber to be upright, and the lower end of the connecting ring clamp on the vise, pull compression damping lever several times, then there should be a stable resistance, pull up resistance should be greater than the downward pressure when resistance, such as resistance to unstable or no resistance, it may be short of oil or internal shock absorber valve parts damage should be repaired or replaced parts. In determining the shock absorbers have a problem or failure, it should first check whether the shock absorber oil spills or traces of old oil spills. Seal gaskets, gasket rupture damaged oil storage cylinder head nut loose. May be oil seals, seal washers failure, should be replaced with new seals. If you still can not eliminate leakage, shock absorbers should be pulled out, if they feel there is no issuer or the severity of the moment, and further examination clearance between the piston and cylinder is too large, whether the damper piston rod bent piston rod cylinder surface and if there is scratched or pull marks. If there is no leakage phenomenon shock absorbers, shock absorbers should check the connecting pins, connecting rods, connecting hole, rubber, bushings and other damage, sealing off, break or fall off place. If these were normal, it should be further decomposed shock absorbers, check with the gap between the piston and cylinder is too large cylinder with or without strain, the valve seal is good, valves and valve seat are tight fitting and minus Zhen's done spring is too soft or broken, take grinding repair or replace parts of the way under the circumstances.

 In addition, the shock absorber in actual use will be issued by the sound of failure, which is mainly due to the shock absorbers and springs,E46 camber arms frame or shaft collision damage or loss, and shock absorber pad dust tube deformation, oil lack of other causes, reasons should be identified, to be repaired. After the shock absorber during the inspection repair should be carried out in a special test bench performance test, when 1mm when resistance frequencies 100 ±, its resistance to stretching and compression stroke stroke shall comply with the provisions, indicating damper normal.

How to buy their vehicles shock absorbers

Vehicle modification does not mean necessarily have the power to change is very large, but it is certainly contrary to the car to change it well apart and full security. To modify shock absorber, its meaning and not just drop the body seeking good-looking it!

The so-called shock absorber damping modification is actually put on the harder, better quality and can cooperate fully with the shock absorbers and springs, select a suitable set of shock absorbers are the most important to the comfort and handling of particularly difficult to achieve a compromise between. In fact, in fact, the chassis suspension


And there is no absolute formula for follow, at most, the majority of people just approaching sensory design it! After all, different size, weight, type and even between models orientation absolutely nothing in common can be copied, and the so-called modified shock absorbers, but can not fully meet the needs of all consumers.

Functionally, the spring is mainly responsible for supporting the weight of the body, and to temporarily absorb, store the energy will cause shock. The role of shock absorber tube, that is, the use of shock absorber damping barrel of oil to the kinetic energy is converted into heat energy conversion, energy vibration suppression during spring compression. Simple in a word to describe the function of shock tube is used to catch the spring.

If fans suspension modification concept itself is nothing, it is best to choose the perfect suit manufacturers have with products, to avoid errors with the problem. And in this type of shock absorber tube being inserted mostly on price, but what is good responsive prone to leakage of monocular type good? Or a long life but the shock reaction flat complex drum good? In fact, these have mainly based on the consumer's own purpose and sensory perception may be! Also in this price adjustable damping can also buy into the product, this can be expanded for use of space, while meeting the needs of the greater use of the product, but fans should pay attention to the amount of its service life, these are the fans making friends suspension should know before conversion.

Precautions modified car shock absorbers

Shock absorber damping modification is actually put on the harder, better quality and can cooperate fully with the shock absorbers and springs, MX5 Coilovers select a suitable set of shock absorbers is the most important, to between comfort and handling particularly difficult to achieve a compromise. A set of adjustable damping shock absorbers, can improve usability, especially in changing the way adjustable shock absorbers like
Down is seriously considering the hardness of the shock compression resistance and spring have additive effects, a set of springs is only one performance, to change the hardness of the spring only to replace another set of springs of different elastic coefficients may have tuning shock absorbers are able to make up for this shortcoming in a suspension conversion process thorniest issue is with shock absorbers and springs,
If your car is lowered by more than 2 inches or spring stiffness increased by more than 20%, you'll have to spring shock absorbers be replaced. Hard to stiffer springs and shock absorbers with each other, because the hardness of the spring is determined by vehicle weight, and heavier vehicles require stiffer shock absorbers. So in racing or high performance car than the average car's shock absorbers
Hard to match the stiffer springs.
If the shock is too soft can cause swinging up and down the body, if it is too hard will cause too much damping, spring is not working, but because of the shock absorber damping effect caused by changes in vehicle height when traveling softer spring (progressive), coupled with stiffer spring and damping adjustable shock absorbers, to complement the hardness of the shock absorber spring strength
Plus damping can be freely adjusted to obtain a high degree of traffic adaptability. Generally soft springs can be maintained to provide better comfort and rugged road passing through the relatively better tracking of time, if the spring is very soft, then it is the case of Italy appears to sit at the end of tolerance, that is, the suspension travel exhausted. If the situation occurs Sit in the corner is visible
For the spring force coefficient becomes infinite (no longer compressed space), the body will produce immediate weight transfer, resulting in the loss of tracking sex. If the car has a long stroke shock, then the situation may be avoided sitting at the end of the occurrence, but the relative body will become very, Mazda Miata Coilovers very high and very high center of gravity of the body means the body, the body
Low center of gravity have a decisive impact on the handling performance, so too soft shock absorbers cause disorder on manipulation.

Caution, Turbo!

In Texas you meet cowboy hats - and the cars of John Hennessey. Quite daring types with large flap and massive power.engine parts Currently leaving the Nissan GT-R with four possible levels the coupling.

 The really brutal PS Firecrackers come in the USA among others from Texas tuner Hennessey Performance. The Department for Business head of John Hennessey pimped mainly on those cars that are already blessed by the manufacturer with plenty of power. This applies certainly to the current coup of the company: the Nissan GT-R. Hennessey is this the way of the "four noble wisdom". This means that not less than four power levels are available for the GT-R. Let's start (series 485 hp) at 600 hp. Three more stages with 650, 700 and 800 hp blow the financial budget of possible customers while up to the pain threshold to make the Hennessey GTR but for purpose weapon at any racetrack. With the exact PS-claim, the tuning company is the way modest.

 In reality, each of the four performance levels makes good 15 hp more. The hefty horsepower and torque increase provides for the 800-hp version of the phenomenal time of 2.6 seconds to 60 mph (Miata Adjustable Coilovers). The quarter mile brings the Hennessey GTR800 in 10.5 seconds behind. The top speed is well above the specified factory 310 km / h for the series GT-R. Hennessey realized the additional power through a complete overhaul of the 3.8-liter V6 twin-turbo engine. Of the charge on the intake to the intercooler and exhaust system more efficient equipment is used. In addition, the clutch and the transmission be used in the extra-PS. Of course, the tuner chassis and wheels also adapts to the new requirements.

Essen Motor Show

Food as it shines and laughs: AUTO IMAGE SPORTS CARS and AUTO BILD MOTORSPORT recorded for the ninth time the best racers and sports cars of the year.

It blows a fresh wind through the Grugahalle, the traditional home of the Essen Motor Show. 2010 is the breeze particularly dynamic. The Motor Show is thundering at full throttle back to its former strength. At least, so briskly in the beginning are the winners of the Race Night 2010 For: In addition to the winners of the German Post Speed ​​Academy of Axel Springer Auto Verlag also drew manufacturer and refiner of the best sports car of the year. Dr. Hans H. Hamer, Publishing Director Car, Computer & Sport, opened the night of Champions and gave his guests in the capable hands of the moderators trio Eve Scheer (VW Scirocco R-Cup), Kai Ebel (Formula 1 reporter) and Stefan Müller (Head of Marketing).

The first highlight of the evening: the awards of the German Post Speed ​​Academy. In the seventh-speed Academy-year, seven candidates were in the squad of the great young talent promotion program. Again at the top: Daniel Abt (18), who has thus made ​​it the first driver, two times in a row to have the front nose at the Speed ​​Academy. The son of DTM team owner Hans-Jürgen Abt made ​​in Formula 3 Cup for voltage, won two races in the highly competitive junior series and was second in the overall standings. He received the largest check for 90,000 euros. "It makes me very proud to take the trophy for the second time back home," said Abbot was happy on his 18th birthday on the financial injection for the next season in the Formula 3 Euro Series. Second place went again Christopher Mies. The 21-year-old fought in the ADAC GT Masters with an Audi R8 LMS of Team Abt Sportsline for the championship with two wins and was runner-up. Pay the commitment: 67,500 euros aid money for the 2011 season was third speed Academy newcomer Mario Farnbacher (18). The Ansbacher rose early in the year from karting in the ADAC Formula Masters at the end of the season and was third. The VW-pilot received a check for 42,500 euros aid money. The other placements: Heiko Hammel (22, fourth place; 20,000 euros; ADAC GT Masters), David Mengesdorf (20, fifth place; 10,000 euros; Porsche Carrera Cup), Maximilian Sandy Knight (21; sixth; 10,000 euros; Seat Leon Supercopa ), Nico Monien (20; seventh place; 0 €; formula 3 Cup).

Abt Golf GTI Edition Dark: Geneva Motor Show 2014

At the Geneva Motor Show 2014 presented tuner Abt Golf GTI Edition Dark. The close in terms of performance on the Golf R and precipitated with aggressive carbon look.

House tuner Abt writes (6 to 16 March 2014) with the Golf GTI Edition Dark another "dark chapter" of his relationship with the VW group at the Geneva Salon. Technically power reaches the tuned GTI to the Golf R, who had dethroned him as a Golf with the greatest power. Visually, the finished im Allgäu Wolfsburg is good. However, the performance can be seen: With 300 PS (base: 230), he moved with the Golf R is, 258 km / h top speed and 5.8 seconds for the sprint from 0 to 100 are real house numbers. Abbot can be when it comes to the performance boost, do not look at the cards. Officially, the 70-hp boost is communicated only as "subtle power boost", you can learn more in Geneva.

Agressive carbon appearance around

At the rear, a vierrohrige sheet marching band in chromium-carbon-suit playing the polynuclear GTI sound.
An extensive body kit completes the Kempten finishing: front spoiler, front grille, headlights, side skirts, rear bumper, rear lights and mirror caps have been modified or replaced by an equal carbon parts. Under the deep-drawn stainless steel rear bumper a vierrohriges orchestra plays with black chrome visors, and in sharp curves taken the wild Golf remains thanks to a special height adjustable suspension kit with sporty stabilizers. 20-inch Abt sports wheels round out the presentation, it tires are mounted in size 235/30. And there remains the reamed GTI only second best. Has yet Abt also announced an upgraded 70 hp Golf R for Geneva, who goes into the race with 370 hp.

Venom GT faster than Veyron

The bitterness at the recent high-speed trip of the US-Hennessey Venom GT super sports: He has no signed and sealed. Despite the record pace of over 430 km / h crown belongs therefore continue the Bugatti Veyron.

The clinch at the fastest street-legal supercar car in the world going into the next round. After the official Guinness world record of the Bugatti Veyron Super Sport in spring 2013 with 415 km / h (factory limited) confirmed now fly back to shreds. John Hennessey wanted the setback can not sit up and sent his Venom GT recently on a NASA runway to attack. The result of high-speed running supported the claim of the American: 270.3 mph,coilover kits ie 435.2 km / h showed the satellite-supported measurement unit. Nevertheless, the 1244 hp US flounder beckons not an official entry in the Guinness Book of Records. Because: According to Guinness, the fastest road-legal car has to be built in a minimum quantity of 30 units from the Venom GT but only 29 vehicles are designed and built so far really only eleven. And the Venom GT is Approved as a Lotus Exige "modified" - that is, as a converted Lotus.

Important to know: The 1,200-hp Bugatti Veyron Super Sport has been measured in the past without as factory speed limit with 431 km / h and 434 km / h. These speeds will not recognize the Guinness organization but because the car only with limit (415 km / h) is sold. The number of participants in the struggle for the crown is limited to three to four protagonists. Hennessey Venom GT In addition to and the Bugatti Veyron Super Sport and the Shelby Ultimate Aero throws every now and again the Fedehandschuh. Most recently in 2007, when he reached a then-record speed of 412 km / h. It remains exciting.

Golf R by Abt with 370 hp

Abt Sportsline at the Geneva Motor Show 2014 the brand new Golf R in the tuning version. The adult of the GTI-brother power increases considerably.

Abt Sportsline presents at the Geneva Auto Salon on 2014 (March 6 to 16) the brand new and first tuning offshoot of the Golf R. And: The World's Largest VW tuner goes straight into the full. Whopping 370 hp tickle the Kempten specialists from the turbo-charged and installed already in the GTI four-cylinder. Output of the plant-R 300 hp. The 70 extra hp of the Abt Golf R will be released in the best tradition by auxiliary control device of the latest generation.

In addition to the prestigious PS specifying Also the maximum torque increases to 100 to 460 Newton meters. The performance of the tuner provides the following information: from 0 to 100 km / h in 4.5 seconds; the speed increases from 250 to 265 cases. Visually makes abbot of the exterior mirror cap on Eyebrows until changed front and rear aprons, a wide body kit in view.

German Special Customs pimp McLaren P1 Night Glow

He is already considered completely sold out, last he made a splash on the Nordschleife, the McLaren P1.audi a6 1.8t turbo Thanks to the hybrid braces lightning quick Brite 916 hp in the asphalt, but tuner GSC still tickles out more.

 German Special Customs has ventured to the brand new McLaren P1, its combination of biturbo V8 (737 hp) and electric motor (179 hp) balanced whopping 916 horses to the rear wheels. To these may be potent 900 Nm of maximum torque, speed up the Renner in just 2.8 seconds from zero to 100 km / h, and allow round 350 hours kilometers. More is more: McLaren P1 Night Glow by GSC But more is still as just proves GSC.audi a4 1.8t turbo The noble tuners from Saxony declared the McLaren P1 short hand for "Night Glow", which is optically and technically sharpened again.

Visually shows the British sportsman with a new body kit, showing, for example, a new front splitter, side blades, larger cooling openings, roof air scoop or a rear wing in XXL. To these may be new side skirts or also new rear diffuser. More Bums finally promises the in-house exhaust system including round tailpipes with diameter of 100 millimeters,audi a3 1.8t turbo which is to pimp the P1 to more than 1,000 hp.

Revamped G-Class: Mercedes G63 AMG MEC Design sharpens

If a tuner for the refinement of Mercedes models of all types is known, then probably MEC Design from Berlin. Just show the "ignition coils" again their skills and have the G-Class refreshed.

 More specifically, MEC Design took the Power Model G 63 AMG with 5.5-liter V8 and 544 hp rich (440 kW) with 760 Nm to the chest, with the tuning but turned out rather decent. Nevertheless, MEC Design has come up with some new products for the luxury off-roader. First and above all visually striking tuning measure are new rims, where MEC Design relies on massive 24-inch model of the house meCCon-series type CC5. New rims, more carbon: G 63 AMG by MEC Design Be equipped with those rims 285er 305er or even rubber, painted the wheels are in black / brushed finish. ignition coil Purely from the optical rim should in any case already noticed her more than courageous and equally cheeky design.

 Also new is the rear silencer, which MEC Design Mercedes G 63 anschraubt. Small catch: To order silencer is that until April 2014,ignition Coil Pack the Berlin For two more ideas in store, namely a carbon treatment for the interior of the G-Class as well as a carbon steering wheel. More info and prices reveals MEC Design on direct request.
