I went through 3 sets of calipers in 7 events. I upgraded in the name of safety, and swapped between models. I also took the 3 points.

And why would you take a +2 point hit and stay with an oem caliper. That makes no sense to me.
I have been running the stock s197 set up and carry a new set of calipers to every event. Orig still on car after 4 years and it hasn't gotten any worse . Yes the pads get all destroyed. Horizontal and vertical plains are shot . You also get rotor flex with 1 pc. rotors which attributes to the vertical wedge . I would bet that if you go to a better caliper you will end up with more rotor problems . My rotors only last 2 weekends and they crack. Cooling duct's and all.
Just my opinion which doesn't mean squat but I wouldn't waste money unless the whole set up is ditched.
considering what I put this stock stuff through I am very impressed with what Ford gave me for brakes .
Aggressive brake pads tear shoo-shiddily-diddily up encluding bearings.
Normally with a good set of brakes you can run a much more rotor friendly pad.
Do your homework before handing over your cash for a brake kit

I don't know if you were responding to the OP, me, or Trevor, so... The GT500 OE caliper (I'm sure you know this) is a Brembo F40 setup with a Ford proprietary inner half that simply bolts to the knuckle, eliminating brackets, adapters, etc., and increases rotor diameter from 13" to 14" I picked up a take-off package for a FRACTION of what a "traditional" big brake kit costs... If I can get the pads and rotors to last longer than the stock setup like I think it will, I'll be money ahead on the deal after the first season.

Money, and to race in CMC. The Cobra brakes are fine for the HP that I plan on running. Also ANY other brakes are an upgrade over the 94-95 Mustang. The front brakes on my '84 Volvo 240 have 4 piston calipers. :shock:

Wow! Was this the cobra PBR calipers? What exactly failed? I've been using the same set of cobra PBRs on my track car for the past 4 seasons as I progressed up to TT last season. I've been running on A6's for the past season. The only thing I've noticed is that they fade by the end of a session and there is a slight pad taper.

Why did you leave this part out in your bolded copy and paste from the rules?

Updating or backdating (without a point’s assessment) with specialty models or between two cars that have model names with different
numbers or letters in them is prohibited, unless specifically approved.


C5, C6, Z06 are all different "numbers or letters".


To be technical... "C5" and "C6" are not model names, its a generation. However I assume "or between two cars that have model names with different numbers or letters in them" applies to the base classification of cars table in the TT rules (where c5 and c6 are defined differently).

If this is true, using the C6 calipers would not be a free mod to ANY C5 corvette.

The only advantage is safety. The C6 caliper is less likely to fail. The pad is identical.



Whats this?? C5 calipers are dangerous?? This is the first im hearing of C5 caliper failures. Perhaps we need to park them all in the interest of safety?


They don't fail as in losing all brakes, but they do spread after some real abuse. And after they spread, they don't go back to normal so braking performance is severely compromised. This is the same dilemma with the stock camaro/firebird calipers. I've gone thru 3-4 sets myself before upgrading to C6 calipers. The 2 points is worth it to rid yourself of that hassle. The weaker caliper will run the same lap time, but only untill it spreads so you have to "milk" the brakes and choose your hot lap in session wisely.

I should have been more clear. That was with my stock 95 mustang calipers. With Hawk blue, and HT-10, as well as carbotech pads. I would get one weekend out of a set of pads if I was lucky. I switched to the Cobra brakes with 2 events left. They were awesome, and I still have 50% pad left.
