WHat they said. Different rotors.
If you want a QUALITY rotor, buy a Brembo OEM replacement rotor from tirerack.com. I beleive they are about $35 each for the GT

ick. Seems like a steep price. Might as well have done the Cobra upgrade on the front.
Mach1 kit is CHEAP.ick. Seems like a steep price. Might as well have done the Cobra upgrade on the front.
read my sig. i have the Brembo 4 piston 2000 Cobra R fronts and cobra rears. these are replacements for those kits. if i had done it all over i wouldve gotten the Wilwood 6 piston front and 4 piston rear brake kits.

Why?
Why? Do the Brembo (2000 Cobra R) four piston calipers not deliver enough stop? I'm turning a GT into a 10 second car and I'm to the point of having to decide which brakes to go with. At first I was just going to go with the standard Cobra conversion, but I'm not so sure that it will stop well enough, and I'm also concerned about brake fade. I was wondering how much of a difference there is in the Cobra PBR caliper and the four-piston Brembo for the $600.00 difference. I mean If I'm going to have to spend a couple thousand, then perhaps I should move all the way up to the Roush/Alcon 14"(front) 13"(rear) rotors and 4-piston calipers, or Bear/Willwood 6-piston...?
**This car is not a straight-line drag car...its built for the twisties and I work the brakes over.

well in reality if i had to do it all over i wouldve gotten a fox-body and make it an all out track car.
im currently upset at my setup after my last open track session. stopped great, no fade, i actually was able to outbrake a 2000 Cobra R into a corner, im assuming i was lighter or he was just being careful. i still have the stock pads that are from Galpher and the Motorcraft/Valeo rear pads. they pull the car down, but they have no initial bite anymore. i can modulate them no problem, i am completely disgusted with Ford's pedal placement, i have to get my foot all out of wack to heel-toe. hell i can heel-toe stock hondas and toyota better than i can my mustang.
another issue i had was heat. my last session maybe 10 laps at Buttonwillow the brakes got to 1300degrees. i have no cooling mods, but just ordered a kit off of a guy on SVTP that looks very high quality.
i am trying different pad combos to find what i like. i got the Hawk HPS for street and am looking at Porterfield or Carbotech for track pads. the nice thing about the 00R setup is when you order pads and there is no listing for a 00R, just look up a dodge viper. also rotor replacement is easy because it uses the 94-04 cobra factory rotors. also pad swaps on the front take a matter of minutes. you just pop out the pins, pull out the pads, push the pistons back, drop in new pads and put the pins in.
the nice thing about the willwood setup si that they replace the caliper actuated parking brake with a drum in disc parking brake. ive spaced before when parking in the pit area and yanked up on the e-brake, then had the pads almost melt onto the rotor.

Thanks!
Aaah, I see. Well my situation is that this car is not a track car at all. Just a street car which I already drive as if auto-x'ing every day, that is about to get a huge dose of HP. I'll get some 1/4 mi timeslips when the car is finished, but I want it to be able to stop whether on a track or the highway. Sounds like the 00R kit will work for me...?
