take a look at the whiteline eccentric bushing kit. They install into the OEM FUCAs and provide +/- 0.5° of adjustment. I put them on my slicktop to replace worn oem bushings and correct for bit of chassis tweak from a front end hit (before I bought the car). They adjustment isn't nearly as easy as other aftermarket FUCAs, but once adjusted they stay put, are quiet and reliable. If you're looking to make regular adjustments for track days or ride height changes, there are much better options, but I'd reccomend them for minor one-time camber correction on a street car.
