Brake question-C6 or Wilwood brakes?
 

Need some help in deciding my front brake upgrades. I have stock 2002 Trans Am brakes front/rear on stock spindles/original hubs. The car will be tracked at once/twice a year eventually, and I'd like to upsize the front brake to handle track duty. Wheels are 18"s (coming).

At this time, I'm trying to decide between C6 set up from Kore3 or go with Wilwood's 6 piston/13" discs. I don't want to decide on one to find out it's not up for track use. DaleTx was using Baer Track (Corvette based), but my understanding is he is upgrading to Wilwood's 6 piston calipers.

Pros of C6: factory support, compatible with AFX spindle (which I may upgrade to later). Cons: 2-piston design -> not sure if up to track duty. Z06 brakes maybe an option, but have to use spacers on my new wheels to clear the calipers.

Pros of Wilwood set up: 6 pistons Aero6 calipers, 2-piece rotors. Cons: may not compatible with AFX spindle without purchasing the adapter brackets?

Any thoughts/suggestions?

I have always been more then happy with all Wilwood stuff we use here in the shop. We change the pads to a race pad when needed.

I have had two different brake set ups on my car so far... and I am in the process of installing a third set up.

For the last couple of years I have been running the Baer Track system with 13" diameter rotors on all four corners and PBR two piston calipers in front (C5) and one piston calipers in the rear (C5). I bought all the parts together in a kit... including a new master cylinder with a 15/16" diameter bore from Baer. This set up has worked well and was a big improvement from my stock brake set up.

The only problem with the current set up is that it takes a lot of force on the pedal to get the car slowed down when running on fast road courses. The brake set up I have now has 2,352 lbs of braking torque when 100 lbs of force is applied to the brake pedal.

By switching out the front calipers to Wilwood Aero6 (big) 6 piston calipers... and the rear to a slightly larger diameter PBR single piston rear caliper... my braking torque will increase to 3,404 lbs when 100 lbs of force is applied to the brake pedal (with the same diameter rotors). Ron Sutton spec'd out my new brake set up and did the math to come up with the numbers for the braking torque. I purchased a kit from Ron that included new spindles, hubs, rotors, and calipers. All the parts are designed fit together properly and clear the inside of the wheel.

If you plan to run your car on high speed road courses... and the caliper will clear the wheels I would recommend to go with the 6 piston caliper set up for sure. It all comes down to how much caliper piston area you have. More piston area provides more braking torque.

Thanks for chiming in Dale.

In talking (more of emailing) with Tobin @ Kore3, I most likely will go with a "hybrid" set up, Wilwood Aero6 calipers/C6 brackets with Kore3's C6 Z51 rotor/hub. I also plan to upgrade the spindles to Speedtech's AFX spindles down the road. Using a Corvette based braking system now will let me reuse most of it when I get the AFX spindles.
