I've been searching around this site and found several opinions on "turning" the rotors on our 8's. What is your opinion? I'm starting to get a shimmy under braking at higher speeds (50+) and I'm curious if I NEED to replace them or if I'm ok to have them turned (machined)

 

you should get a measurement of the brake rotor to make sure you can machine the brake rotor and still be within factory spec. however if you drive rather aggressively then it might be a better idea to replace the brake rotor and start off with a new thick surface

Awesome write-up. Gonna go home and replace rotors, do proper break-in procedures. Gettin' some pretty bad wobbling during breaking... will update with if their advice works or not.
