Replacement rotors for track use

[pnolan]

Car pretty much used just for DE's.   I was researching slotted rotors and was concerned about two things:

1) Tire Rack has DBA slotted rotors for my car, but has a note on their website regarding using for track use.  Possibly just a CYA note for anything track related



Brake Rotors and Track Use

Slotted, drilled or dimpled rotors offered as OEM replacements should not be considered appropriate for high-speed track use.

While grooved, drilled and slotted rotors offer an enhanced appearance and add some resistance to the boundary layer of gasses that can build up between the pad and rotor, they are not designed to withstand the extreme temperatures that are produced on the racetrack. If they are used on the track, it is very important that the rotors be carefully inspected and should not be driven on if even minor signs of deterioration are seen. Note, too, that if these products are used on the track they are not warrantable.

(Was not as concerned about this warning as the OEM rotors from Porsche are cross-drilled rotors.)


2) Didn't know anything about DBA and reputation etc
