Old shocks were worn out and bump stops were completely disintegrated so I decided to use that as an excuse to buy these coilovers. On the softest setting the car is just barely stiffer than the stock Bilstein’s and on full hard they are extremely stiff, too stiff for street use even. The rear adjustment extension is a must buy unless you like tearing apart your trunk to make any adjustments. Fitment is perfect and I had no issues with the installation which only took a couple hours.
