Excellent Product
I installed these arms on my IS 350 AWD, and was able to dial in the camber angle precisely. Immediate results were a huge reduction in road noise, complete elimination of the infamous "tire wear monster" on the IS series from Lexus, and an overall more solid footprint feel on cornering. If you're looking to take control over the IS stock (and rather inflexible) camber angles, this is a much better approach than replacing the bushing, in my opinion at least.
