i've ridden in Tein springs...not that great...and the car is lowered a lot.
i have Hotchkis and the ride isn't superb, a bit bouncy...but the ride height is more livable...not so drastic.
if you wanna wait another week or so i'll sell you my Hotchkis set, i've only had them on for two weeks. Save you about $75-100 also. Im going w/IPP coilovers.
