Here they are in the front hubs.
This is a factory RX-8 18x8 wheel. It's funny how thin of a wheel you need to be flush when you're running zero camber.
This is factory S13 control arms with the factory lock stop, on a 17x7 G35 wheel with a 15mm spacer. Unfortunately the trailing wheel still hits the front of the LCA, but I think with tires the tire will hit the tension rod before this happens. An aftermarket tubular control arm would fix this. I'll have to make a small lock stop to try and limit the arm for now, as I imagine the 17x8s will make this worse.
