installed these on my project car (9-3og Conv. Aero, with a Stage 5+ set-up). Koni adj. all around, Viggen rescue kit, s.o.
Bottom line: the car handles 100% better: under hard acceleration, it does not lean backwards, on bumps and hops it stays on the road and under hard steering it follows the direction I point!
Great upgrade for highly powered cars!
