Coilover Smart Forfour W454 (04~06) Super Racing. Super Racing coilover is used particularly in track, rally asphalt, drift and drag.

There are 2 adjustment knobs in this unit. One for the damping setting inside the barrel of shock absorber, the other is used to adjust the damping setting on the nitrogen bottle.

The compression and rebound damping settings can be adjusted separately, and above-mentioned adjustment knobs can be adjusteed separately as well. There are 1024 different settings to adjust.

This version can increase the impact of the barrel oil and the nitrogen gas space to increase the impact. The best stability of the body allows the oil temperature to be kept at the optimum working temperature for long time and intense operation. Make any changes during the operation.

Our design is oil and gas separately for monotube. There are diameter 44mm pistons in the strut which can contain large amount volume of shock oil for handling everlastingly and prevent the shocks from exhaustion after long-term use and absorb the bumps caused by the uneven roads. (We teat it for a million times)

All McPherson coilovers come with pillowball upper mount with camber plate. It adjusts the camber of the tires and get the tires have better turn in fast speed and enhance the stability of the vehicles.

Each of our versions use the highest density foam for buffing, is not use general rubber. Because the foam have the highest density space, which absorb the huge compression force. Even if the cost of the foam is higher than rubber, we adhere to offer the best quality at the lower cost.
