I wanted the exact same thing and ended up going with the Eibach Pro Street kit which is just a rebranded KW1. Lowered 20mm all round, front camber was well within specs, but I opted to fit Eibach camper arms and bolts on the rear (just in case) to save on the labour.
Ride is still very good, and it has tightened up the handling a fair bit, and stll clears all the monster speed bumps we have down here. Photo is from when they were fitted, they have settled about another few mm now I reckon
