The ultimate in handling performance from Koni. This kit includes front and rear springs, aggressively tuned adjustable oil valve dampers and threaded perches.
Coilovers are defined by their threaded spring perches, allowing both the adjustment of ride height and allowing for track-tuning such as corner balancing.
The springs in this set are much more aggressive than stock. With spring rates of 350 in the front and 190 in the rear, these will greatly reduce body roll and front end-dive, keeping the car firmly, flatly planted even in the most aggressive driving situations.
Koni's 1150 kit is valved more aggressively than the 1130 kit, and provides dramatically improved handling along with a controlled ride.
If you prefer, you can match these dampers and perches with any 2.5" spring, up to 700 lb/in.
