Now,without shims,you run -1.30!!Better handling is the idea, only gona run 1 degree of camber
Id concentrate on the front end first. E.g camber bolts, custom geo, springs dampers etc.
Get a Whiteline though, they are a great bit of kit.
+10000000000000000If you do decide to get camber shims dont get the crappy plastic ones from K-tec, buy some metal ones from Pure Motorsport
