Right ok, so I haven't managed to do this yet, things keep popping up, but as it's bank holiday weekend, it's being done. Have cleaned up all the suspension, ready to do, as some of you may or may not know I purchased some new shoes for it.
Right now for the question
I have numerous spacers that came with the wheels all in pairs 25mm, 15mm, 10mm and 5mm. Which sizes should I use for front and which for back. The guy I bought the wheels from couldn't remember if et was 35 or 38, but i've followed a guide, and got roughly 40.
All advice welcome
