So, we finally managed to get the wheels on with a lot of brute force from Bob!! Can't thank this man enough for helping me get these on!
We basically rolled and flared the arches, we managed to get just over an inch extra on each side.
Here's how it went...
20mm Spacer wasn't enough for the Rolling tool to clear the brembo....
Flare!
Turns out with 20mm spaces on (I always though we could get away with 15/16mm, but turns out the old wheel hub threads were sticking to far out of the spacer, so the wheel wasn't sitting flush with the spacer, it was essentially a 24mm spacer. So we burnt those off!
