Do it right from the beginning, continue to improve, get plenty of seat time, and I believe your learning curve time will be shorter.
Race tires, coilovers ect, are very good at masking mistakes. You will be faster if you make and correct mistakes prior to upgrading the car.

Thanks for all the input guys. I think I will go with the Brembo's and stock pads to start with.

My goal going out there isn't to prove I'm a good driver. I know I'm a very novice race driver! So I want to go out there, and learn the fundamentals, and slowly build up more momentum through the twisty bits.

Once again, thanks for all the input. I'll let you know how it goes in the spring!

I'm kind of late to the party but my camaro is pretty much a track only car. I have experienced about every kind of failure you can possibly have (most of these on other track cars), especially with brakes. The most important thing to change is the fluid. If the fluid boils you will have gas bubbles in the brake lines and when you stomp the pedal nothing happens unless you pump the crap out of it. Once some of the fluid is vaporized you will never have good brakes until you replace all the fluid and thoroughly bleed the system. I use Motul 660 fluid, I have heard the Castrol is good. If you have good brake fluid you will always have pedal pressure.

I personally think your stock rotors and calipers could work fine if you if you put the right brake pad on the car. If you stomp the brakes hard at race speed and feel the ABS system stopping lock-up, then you have big enough calipers....period. It is that simple. If your calipers can lock the tires you don't need bigger calipers. If you put a race compound tire on the car the brakes will need a lot more torque to lock the tires.

Brake pads have a preferred temp range and have various torque ratings. The problem with many racing pads is they must get warmed up before they grip. This is really bad in a street car because if you go to the grocery store you will never get the pads warm enough and you will be stomping on the pedal to try to stop the car especially, if it is raining. The plus side is your rotors can be glowing red hot and they will still stop the car fine. As a matter of fact some of the race pads, the hotter you get them the better they stop. The problem with most "street pads" is that once they get too hot they melt and no longer grip the rotors. This will be the hard pedal with no stop sensation Norm described. Hawk HP will do this about 1000 degrees, I've melted a set down completely when I was testing combos. This leaves a couple of options, you can either swap pads just for track days. Or you can get a good all around temp pad. The better the temp range is on the pad, the more street problems it has in general. I'm using porterfield R4 racing pads. They have the best temp range of any pad I have ever tested and stop like mad. They also make tons of dust, squeal at certain temps and eat a set of rotors in the time the pads wear out. But I never change them and they always stop. Probably not the best pad for a daily driver but my car has almost as many track miles as it has road miles.

Putting a bigger rotor on the car will help cool and keep the temps down but you could get more gain from a stock sized 2 piece rotor with an extended air channel like comes stock on the ZL1. It you put a fresh air duct to the brakes this will help more than a bigger rotor and caliper. I did this on my other cars....ZL1 has this stuff stock.

Honestly the bigger caliper just gives the system potential to make more heat and if you are not prepared to handle the increased heat it won't help you much.

I'm mixed on upgrading your car suspension and tires. Some people I know are hardcore about practicing completely stock before you make upgrades. I don't buy into this fully. I think you learn to drive what you have. If you start to drive the performance edge of a highly upgraded car you will have a lot more speed and possibly more severe consequences if you cross the line. Generally, the best drivers walk the line. If you don't feel the need to hang out on the performance edge of your car, the track experience is generally better on racing rubber with suspension upgrades because you can go a lot faster without as much skill. If you really want to learn to drive, you have to get comfortable on the line. As you get better, you will find that it is really hard on the car to hang on the ragged edge and if you back off just a little it is a lot easier on brakes, tires and engine cooling without hardly any difference in lap times. Coaching and instruction from experienced drivers is well worth the investment. Hope this helps.

So, i'm generally confused by your post Jessrayo.

There is no stock sized 2 piece rotor for the V6 that I'm aware of, for starters. For instance, the racing brake 2 piece is only available for the SS, not my car. Secondly, the best pad I've found is the Hawk HP+ for the V6. There simply isn't the range of pads available for the V6 brakes as there are for the SS.

And honestly, Have you tried this? You have a ZL1. You have massive rotors up front. Massive!

There have been guys that have gone all out with the V6 brakes. Went with the JDP front brake cooling ducts, HP+ pads, and slotted and cross drilled rotors. Fade was still a big issue. They then went up to a more or less stock SS setup, and the fade became manageable.

Like, if the V6 brakes were perfectly acceptable on the track, then GM wouldn't have gone to Brembo's on the SS. Full stop. The V6 actually stops better than the SS does, for one stop. (106' vs 109' I think?). By your logic, the SS would just have better pads, and be race ready! Why add an expensive part with no benefit?

The SS rotors are between 30 and 35 % larger in terms of flat surface area. That's a pretty big difference. Given the better design of the brembo calipers and the size difference, I'd be willing to be that the actual cooling difference improvement in the stock setup is closer to 40%.

That's a pretty substantial difference.

Sorry for the confusion. I did not realize that good 2 piece rotors and racing pads were not available in the V6 sizes. I can tell you that if the best pads you can find are hawk HP+ then you better get a different rotor/caliper because in my opinion those are crap at real racing speeds. I am in my first season racing these Camaros and as you pointed out I started with the ZL1 that has huge rotors.

The main point I was trying to make is, bigger is not necessarily better. The only thing I do not like about my Camaro is I think it is too heavy. I can pretty much guarentee you that the NASCAR braking systems have smaller rotors, calipers and pads than my ZL1 yet will stop just as well or better. All of this is unsprung weight, I merely suggested a smaller rotor and pad could do the job if the right combination was avbailable. From what you have posted, an SS upgrade my be a very good choice. I obviously have dumped a lot of money in my car but if I was complety swapping the rotors and calipers I would consider a full racing system from someone like brembo or wilwood just so I could save weight. You don't need a huge rotor to stop the car, you need an efficient one. If you want the convience of GM parts compatibility Then go with a proven combination like the SS or ZL1. I can tell you that the ZL1 parts do the job with absolutely no fade as long as you change to the right pads and fluid, even with 800 hp and race tires. Once again sorry for the confusion.

So... I'm going to have to take that back.

Apparently, You can get race pads for the V6. Carbotech, and Cobalt Friction both make race pads for the V6.

I spoke with Danny at Carbotech, and he said he would throw on the XP12 pads on front, and the XP8 pads on the rear.

The XP12 pads have a temp range of 250F to 2000F.

I'm now hoping that I won't have to upgrade to the Brembos. I still can't find a good 2-piece rotor, but there are some upgraded rotors available. To my knowledge, no one has tried these high performance pads on the Camaro V6.

2000F is well past the point where steel glows red hot, which is impressive... Hopefully this will provide me with the fade resistance I need.

If I can get away without the Brembo's I can save a substantial amount of money towards better tires or a separate set of rims with track tires. Or more racing instruction.

I'll give it a rip, and report back this spring.

As long as the fluid holds up and the pads still bite the rotors really don't matter if they get hot. I tossed 2 sets of rotors that were full of heat cracks and then the mechanic at the race track told me that just because they look like shattered glass, doesn't effect the performance. My current set of front rotors are full of heat cracks and have done 3 track days without trouble. The paint on my calipers is burned from heat. Just make sure you regularly change the brake fluid and it will save weight and money.

Get a good full faced helmet snell 2010. Make sure everything is working and tight and snug. Upgrade to dot4 fluid. Check brakes. Need good pads. Of course you can upgrade to ss brembos easily...or other options. Make sure tires are not damaged in any way. Go to track wanting to learn and stay withen your limits and have fun.

I would get good street performance tires...no need to go full bore before you know you wanna do it.

Helmet is definitely top of my list.

Local place I can get a snell 2010 helmet for around $150. Will change to a good high temp brake fluid before the event.

For tires, I'm either going with the Pirelli's or Pilot Super Sports. I may eventually go to a a seperate set of rims with R-Comps, but not for a few years.

I'm definitely going out there with no delusions of grandeur. I'm going out there to learn how to be a better driver. I've driven with a local guy (who is admittedly quite good), and I know I have a lot to learn! Should be fun!

Go with SPCBA's recommendation. Keep it simple at first. There's a very good reason why you shouldn't upgrade your car's performance BEFORE you are comfortably in command of its stock performance. Risk. Yes more power and an upgraded suspension will perform better; especially in the hands of someone who knows what they're doing, but in the hands of a novice it's way too easy to start driving faster than your skill level just because the hardware allows it. And then when you find yourself in trouble, you don't have the skill to safely drive your way out of it... and because you're going faster than your skill would have allowed with the stock setup, you're now far more likely to either do serious damage to your car; somebody else's car; and/or injury. Even death.

The faster you're going, the fewer seconds you have to recognize an issue and correct for it. Slower speeds allow for more time to make mistakes and fix them before you hit something. And in the process you're learning what mistakes "feel" like and what to do or not do to fix them. Seat time is more important for you now than car upgrades. Go with SPCBA's recommendation; it's spot on.

I'm real late to the party :(

2 years ago I took the stock pads off my v6 and put on Carbotech xp8 pads on all 4 corners. I have 2 years of street and track driving on them.
I can stand the little bit of cold squeal
Nothing better than being able to STAND on them at the 200 marker going into 11A and make the turn lap after lap.
I just need to get rid of the pesky 118 mph limiter now that I have better tires

Car works best on tight courses for me that's AMP, Barber, Roebling

Just to confirm Jimbow...

You're doing this with the stock V6 Calipers? Not the SS brakes?

I had stock SS wheels/tires on my ZL1 when my stock wheels were being painted and I noticed a HUGE difference in handling, I haven't had alot of different experiences besides that but based on that there is a huge difference with a good track/performance tire
