So let me get this straight someone here said you need a camber kit no matter what kind of drop you do... I know of plenty of HFP Suspension guys (1 inch drop all around), with NO CAMBER KITS, they just go get their car aligned to stock specs.
Couldn't you just do this with Tein S-techs? Get a stock alignment.
Edit: Obviously if you want to handle better you don't get a stock alignment, but this is just to answer the OP's question.
