The alloy lower arm / adjustable ball joint is a good mod from SuperPro. Allows that bit more adjustment you're after.
I have them coupled with ground control top mounts. Around 3ยบ camber combined!
Id advise trying the balljoints alone 1st, although you'd pay for another alignment / geo setup if you added top mounts later. I think the top mounts can add a bit extra firmness and in some cases a bit of noise. If you're more concerned about performance and handling, go for it! Mine handles amazingly
