If you're going to do strictly auto-x then the C6 Z51 Kore 3 brakes are plenty of brake for that. I would stick with a floating caliper in the rear with a non floating axle to combat knock back.

The manual vs power is really a preference imo, I prefer power brakes because I find it easier to finesse the pedals when your not using so much leg effort on the brake pedal.

Knock back is one of my concerns. I have experienced that in the Silver car and want to avoid it if possible. Thanks Tim.

Yes, what Tim said. I called Tobin and he talked me down from the rigid caliper Z06 style. I couldn't be happier with my C6 Z51's, with upgraded DBA rotors and Hawk HP+ pads. I chose manual and love the "feel" of them.
Of the 7 or 8 autocrosses I did last year, I think I only locked my fronts one time at Indy. Very easy to modulate the manual pedal in my opinion.
FWIW, I have not felt knockback at all with a solid axle and the floating calipers.

Thanks. I emailed him last night night and will follow up on Monday. I did a little research last night on the DBA rotor. How do you think it helps? Thanks for the info, I really appreciate it.

I'm running Kore3 C5 "big brake" with 12.8" DBA, Hawk HP+ and Wilwood 7/8" manual master and love them. I prefer the manual feel due to my motorcycle background. DBA rotor isn't magical, just good fundamentals - 1.25" thick, good cooling vanes, not drill so less chance for stress cracking. IMO I have more brake than my front 245/40/18 NT05's can handle. Call Tobin, he'll spend the time and ask the right questions required to deliver brakes that meet your needs.

Sieg nailed it. Not magic, just better quality castings. I have almost 3,000 miles and lot's of aggressive driving, autocrosses, and two road courses, the rotors look perfect still. I've heard of warping issues with the GM ones also.

I'd agree on the braking power with Sieg, I had the same front tire and could easily lock them up at will. The Rivals offer more grip for sure, but still more brake than tire. Hoping 265's will help

Great info guys. I appreciate all the feedback. Right now I have 275 fronts but am thinking of running a 315. I will follow up with Tobin tomorrow.

Thanks, Cal.

[Mac&Otto]

Thanks again guys for all the info on the brakes. I talked to Tobin a few times in last couple of days and he walked me through my options. He was very helpful and I feel confident after talking to him. I've decided to go with Kore 3 C6-Z51 with Hawk HP Plus pads and the DBA 5000 fronts and DBA 4000 rears. He is not far from me and I'm going to make a trip his direction soon so I will be able to stop buy and see him. Thanks again.

Hard to beat the Z51 cost and performance wise. We still run stock rotors cause you can almost get them for free if you look.

What master did you go with? 1 1/8 or 7/8?

Vince, Tobin recommended the 7/8" Wilwood since I went full manual. Used factory pedal in the manual, upper hole, position. Good pedal travel, not too much and very firm at the braking position.

Cal, you'll be happy with that setup I think. Looking forward to updates!
