I fitted the same type of kit from an US mob, with exception of drop spindles. The kit I had, made the offset and extra 0.5" on either side. I also bought an 2" narrow beam so it worked out with the brake kit that I decreased mine by 0.5" on each side.
Hope this helps, Kevin.
I thought rebuilding a VW would be cheap - Shit I was wrong, just don't let the wife know !!!!
