I'm inspecting my brakes after my Homestead track day and noticing some grooves on my right front. About twice as much as on the left front. The pads are Hawk+ on RotorPros slotted rotors.

In the past, on my much smaller cars, SVT Focus and MR2, I have pretty much ignored the grooving and just put new pads on, etc.

When should you think about turning or replacing the rotors? Do you ever replace just one?
