Rotor Wear at the Track

My OE rotors got groovy as soon as I got good pads. Never thought much about it.

I get unusual wear on my OEM rotors. I get grooves, some deep pits, some glazing, and loud squeel (not just squeeks). It's mostly the pits I'm worried about.

I'm wondering if using a different rotor brand, or if going with slotted or cross drilled rotors would help reduce the unusual wear.

I've been using OEM rotors, Hawk HPPlus pads, and r-compound tires.

Is heat simply the issue? or could it be that the rotors are too soft* for this tire/pad combination?

For now I'm considering slotted and/or cross drilled rotors with some ducting.

there is your problem.

got a picture? my guess is your hp+ is overheating and depositing on the rotor which is very easy running on r-comps.

you are correct. your hp+ are fading quicker than your R compounds can react

I've never used the Hawk pads but its my impression that they are a legacy compound and not as rotor friendly as some of the newer pad compounds, I could be wrong. My rotors are smooth and even until I take them to the track and then they get groovy, but so what, it doesn't really hurt anything. It just takes a little longer for a new pad to match the surface that's all. R-compounds and track driving are going to etch your rotors no matter what. If you are doing road courses I'm a big believer in dedicated track pads. Cooling will help but not eliminate pad and rotor wear. Remove the dust shields if you haven't already and make some custom dedicated brake ducts like Xqizit and I did.
