The kit is something like $1500+ (I think). The strut is fully adjustable, with 24 positions. The coil-over setup is (naturally) height adjustable. The ride is rather harsh, IIRC. The Koni SA with Ground Control combo is much more streetable, and slightly cheeper. Unless you plan on road-racing all the time, it could be considered overkill compared to the Koni/GC combo.
