Great product. If you plan to modify your suspension (e.g. ride height, aftermarket shocks, etc..), then you should really consider getting this. I first try using the kca399 kit only to adjust the rear camber. But then, the stock toe bolt was not able to compensate for the added camber, since these two interact with one another. Plus, the camber and toe components are so much easier to adjust with this kit. The kca399 is kind of a pain to adjust.
High quality product from Whiteline as usual. Great performance upgrade if you’re lowered or raised - allows way more control over geometry of the rear end.
