The OEM rotors are very capable at the track, the only problem is they have the same problem all drilled/holed rotors have - they crack sooner than blanks or slotted rotors. On a track where brakes are heavily taxed they will crack beyond limits in a few weekends. Other tracks, not so much, but still will not outlast blanks or slotted rotors.

Rotor performance is really about longevity. While there are some differences in alloys, they are all cast iron, and the only real differences are how they are vented. The surface friction differences can be solved with pad selection, so the real question is, how long do you want them to last under severe use? You will be hard pressed to beat the OEM rotors without spending a lot more money up front.

I still have them on my car, and with my Ferodo DS2500 Pads (obtained from Forum vendor SpeedFreaksUSA) they provide very powerful performance. They are still true and are wearing very well.

However, because of my past experiences with the flaking paint on the hats, the substandard packaging they were shipped with and the, IMHO, extremely poor customer service from the vender I cannot recommend them.

If you do decide to go with them, I recommend against paying extra for the painting of the hats.
