So, I finally got sorted.. I have Sti 08+ rear bearings which are a bolt on fit, as long as you can drill the rear disc out.
I have also bought Sti 08+ front hubs and am now considering the options for front uprights. Brypar make billet Aluminium hubs for the FRS/BRZ/86 platform which accept the Sti bearing. I may make my own, either billet or fabricated?
And here's why I will not use conversion spacers or any bolt on spacer for that matter.. especially with sticky rubber on track
I found the pic somewhere on the net..
