if you want the front and rear to be just slightly above the fender, go with hotchkis. they ride great, add better handling capabilities, and drop the car the perfect amount.
try to stay away from coilover sleeves because once you lower your car too much, your shocks will go bad quick and u'll need new shocks. if you plan on getting aftermarket shocks like koni, TRD
, or watevers, coilover sleeves will work fine.
