H&R's VTF kit swaps the factory springs for progressive rate units that sit on precision machined threaded collars, so ride height is dialed in on the car instead of being fixed by the spring. Adjustment spans roughly 20 to 40 mm at the front axle and 20 to 35 mm at the rear. Rates are tuned to run on the car's original electronic dampers, so the adaptive suspension keeps working and the factory shocks stay on the car. The springs are made in Germany from light weight, high tensile strength spring steel alloy, are TÜV approved and carry H&R's limited lifetime warranty.
