The CUSCO type and the ones available from element motorsport in the states both say that they allow more negative camber....but if your car is lowered it's positive camber adjusters that you would need ... correct?
what i've found out about the cuso adjustables is....
There are four settings that it can be set to, through the use of 4 bolts on a sliding rail, and two locking bolts. The settings are stock, -4mm, -8mm and -12mm, with increasing negative camber respectively.
So if i'm not mistaken the CUSCO would make tyre wear worse not better? :(
