the fronts i got which were 2 inch lower, were about half the height of the stockers, definately not captive plus it had the tendancy to skip along the road if you tried to brake over bumby roads.
the backs which were supposedly 1.5 inch lower, actually sat at stock height. also the rates were really dodgy too.
the kyb shocks are ok for the money, but go whiteline or kmac for springs.
or if you know someone in japan tokico hts for under 500 bucks for all 4!.
