sorry, i guess i should've been clearer. when i said that most likely nothing should have to be modified, i meant the fender well, control arm, etc. won't have to be modded to fit. with the anchor bolt style kits, some people have had to make mods to those or other parts to make things fit without any hitting/rubbing. completely correcting your camber to 0° isn't absolutely necessary, though. i believe spec is from -1.0° to +1.0°. most cars will have slightly negative anyway. it's just that when you get towards +/-1.7° or above you're more likely to have the abnormal tire wear. nobody can guarantee you anything because every single car is different and reacts differently from other cars with the same setup. i had -1.9° camber on the front of mine and got the SPC ball joint kit that corrects up to 1.5°. i couldn't get to 0°, but was well within spec after installation. my rear wheels were around -1.7° and were corrected to -0.8°.
