Needing some advice, done lots of forum searches but can't find the answer.
I have a narrow body mk1 with a Williams rear beam. The calipers were from an abs model. I got the smaller spacer to try a bring the beam to rsi spec but there is no way to tighten the hub up correctly or move the caliper far enough in.
So what exactly makes the rsi beam narrower?
Any knowledge or pics would help.
Thanks!
