The stock brakes bite (in a bad way, unfortunately). My whole philosophy of auto-modification is backwards from norm. When somebody else might be slapping an aftercat on their car, I'm adding good brakes, so I'm serious about brakes.
I agree the R brakes are better than the standard Cobras, and I should have mentioned that he will need 17" wheels to use them (I'm not sure, but he may need more space for the R brake calipers...). The R brakes also cost more, and if you need 18" wheels, the cost will be high (I run 18" wheels, so no problem for me, but we might need to hear from someone on the forum running Brembo R brakes with 17" wheels).
Cryotreating is new to this old dog - but I've read the treatment really does work. How much does it cost?
I suspect you don't have the problems with your brakes because you avoided the cross-drilled AND slotted path (picking either one for the street works fine - just not both). Cross-drilling (old school) does indeed promote cracks at track speeds and loads. Cross slotting (slots that run all the way through the rotor) can work, particularly on solid rotors.
For a street setup (with rare road race use) I suspect the Cobra brakes would do fine. The R's are still widely available and well thought-out - if you can stand the $$$.
Overall, I think your and my advice fits neatly together. Good luck with your track events. Just curious - what sort of suspension modifications have you made?

If your rotors are not warped or show signs of cracking then there is no reason to replace them. Unless, like me you agree that the GT brakes are inadequate for a heavy powerful car, especially if you ever plan to track your car as I do. Do it right the first time if you want a serious upgrade. Your best bet is to go with the :worship 2000 Cobra R Brembo Kit or for less $$ you can settle for a regular Cobra 13inch upgrade. If you do replace your rotors have them cryotreated first. www.cryoscience.com Regarding drilled or slotted or both, both D&S looks good on the street though if you track the car go slotted at most. Per a Brembo Rep: A drilled rotor will promote cracking from the holes as it heats and cools too quickly, because of the holes, while on track. Ceramic pad technology is marketed as superior to simi-metalic and was created for longer pad life with more resistance to fading. Baer Brakes recommends SBS pads, they are ceramic, I run the Track pad with EradiSpeed+ f/r on my Cobra, stock calipers for now. SBS Track pads are the middle of the three SBS pad levels. I do have a hint of squeak during gentle very low speed stopping for the first few miles until some heat builds then it goes away, never heard clicking. This squeaking sound, I think it sounds cool, is the same sound a race car makes in the pits before it goes out on track, once on track you don't here it again. My experience with EBC & PFriction was not favorable. When I need pads I will again buy SBS. Go to www.baer.com or www.brembo.com and see for yourself. Also consider steal braided lines. Changing pads on an ABS equipped car is the same as non ABS car. :smoke:
