last year i tried running more offset on the front and could not get more than 3 or 4 shims stacked between the axle and block without losing thread on the nut.
so, to add 2mm to the front axle, does this mean you drop the lock nut? or maybe you grind a relief on the inner surface of the stearing block?
I just dropped the nut. THreading the axle into the block holds fine
