I also loosened up my bellvile washer a little to make it easier to steer, and that seems to have helped the

I've got fiberfrax and foil tape around the left gear leg and just foil tape around the right gear leg (because there wasn't room for the fiberfrax.) I routinely touch the rotors soon after I park to see how hot they're getting. They were normally never to hot too touch. With the wheel pants they are hotter, but after loosening the Bellville washer I don't burn my finger when I touch them. I think
