There was a good amount of BFH work! Plus I had to have my sliders cut down about 1" on the front. The stock rims are +38 and of course the stock rim with the stock tire size does not stick out at all, so that 51mm won't stick out that amount, it will be less. A 0 offset is a little better. The stock rims are 7" wide and my Borbets were 8", so that CAN also factor in a bit with the wider rubber, depending on the tire size you go with.
