Thank you very much for the info.

I would assume the R31 inserts would be more comman and might have good aftermarket options.

Hoping to drill the new mount holes up as high as possible and if it's not going to take to long I'll also attempt to make a spacer for the ball joint to lower the other end so bump steer is t effected as much by lowering it.

It is a budget build for now, more just for fun and amature club level events.

I will be doing a hydraulic handbrake for the rears anday have to invest in a bias control anyway.

Is the wheel fitment issue that the hub face is closer to the strut than others or just the hub to strut camber is less?
I hope to run negative offset wheels and reshape car body later if needed. (I enjoy a little fabrication, haha).
