I have an older style of Grove wheels and brakes that came with my TCOW kit.
After a few hundred landings I noticed that the out board side of the caliper is rubbing the inside of one of my 26" Goodyears.
I had thought about making a spacer to space the rotor out from the wheel to move the caliper farther inboard.
I understand that the new style Grove wheels have the rotore spaced more inboard than mine.
Anybody run into this, and what was your fix?
