I put about two sentences in the wiki about CA brakes over certain 13 inch wheels and I haven't had the patience to put time in. I was planning on linking the other relevant threads in the first post of this thread but I suppose that would make more sense if I did it as a wiki.
Also I gave my mate the other set of 910 LCA's and apparently (I'm going to properly measure the left over one since he's made a staggered arrangement for a speedway car) it's hard to tell but they're 10mm longer than the R31 LCA's. Poo, I could of had cheaper camber.
