I DONT HAVE LCA'S. my setup IS NOT that aggressive to need rear camber to make it fit, if anyhitng i'd get them to run LESS camber in the rear to get more of a contact patch but right now i'm only at -2.2 which is PERFECT for cornering.
if you must buy them, get gtspec arms.
hit them with some anti-seize before you put them on and you're good to go.
and that racecar look is EXATLY what i was going for with mine. think i came pretty close.
