Does anybody know of any companies or individuals that can straighten rotors and has quick turn around?
The carrier or braking surface? I Bought a pair of Brembo cast iron rotors once and discovered one of the aluminum carriers had a bit of runout. Frame Straightening Services remedied that for me. I wouldn’t do that with the braking surface, though. The Brembos are pretty rare now, so it wasn’t like I was trying to fix an OEM GSXR600 rotor. http://www.framestraightsystem.com/MotorcycleWheelRepair.htm
I used this guy, and he was fantastic: https://truedisk.net/ I have used frame straight for a wheel, and while the work was quality the customer service was a little light.
FWIW. I've used that guy and whatever he did to my rotors didn't work. I put the rotors back on and still had considerable run out. I ended up putting full floating Brembo buttons on and solved my problem.
for street use, this may be worth your time.. for racing? just get new. tried a couple different straightening companies. wasn't worth the time and money.
