900hp and 4100lbs make for an adventure on the road course. Already did the track g lock pads and motul fluid.
Was at sema and asked a lot of vendors and not many had anything with a few saying-soon???

Any other weekend guys finding a significant improvement over stock for $3-$5k?

I think most people are fine with the stock setup. Other than swapping out pads to g lock line you did.

The only next step I see would be carbon ceramics to help with the extra heat you're generating with that extra horsepower you have.

stock is more than adequate with high temp DOT 4 fluid and a better brake pad

I highly disagree. Stock is not adequate at this power level.

This is what I will get if I ever find the limit of the stock brakes. They look incredible too.

Edit: It will be impossible to improve on the already incredible OEM brakes for $3-5k.

The kit suggested below costs $10K for fronts + rears... given your massive extra power and a bit of extra weight, what limit of the stock ZL1 setup did you bump into? Is it heat management, stopping power (max deceleration), or something else?

Power affects acceleration mostly and top speed occasionally, so I'm not seeing how it affects braking. How often are you seeing 160+mph? ...because I routinely stop from 150+mph 15-20 times in a 20 minute session at the track, about 5-6 times per day. That's 75-100 times a day and if I start the day with new pads I usually would still have 6-8mm of pad left and no cracking on the rotors.

Based on my personal experience, I have to call BS, albeit respectfully, on the idea that the stock brakes are not enough simply based on how much horsepower your car has.

As someone else suggested, you may want to look into high temp brake fluid. I recommend Castrol SRF, and PFC 665 Racing Brake Fluid (Motul is junk). These can be left in the car for street driving and they give consistent performance at the track. No more mushy pedal.

*GM recommends changing the brake fluid as well if you're going to be running the car hard.

Try better fluid before going to an exotic brake setup. You may be pleasantly surprised.

One last thing, bleeding the car correctly is a must. No matter what fluid you're using, if you have air in the system the brakes will feel like crap and will get worse as they heat up.

I have quite a bit of data recorded with stock brakes vs updated stock brakes and the results are staggering. As in, using near 1000psi less brake pressure to get the car stopped. I’ve run some decent times in both my SLE and ZLE and braking performance has been nothing but stellar. I use Giro rotors, GM Dot 4, stainless lines and either Ferodo or Cobalt pads.

If you need more than that, there is something fundamentally wrong.

IMHO Hawk DTC 70/60 Front/Rear, Castro SRF are tough to beat. The Motul fluid can’t handle the temperatures you’ll see. Which compounds were you using? You may need more aggressive pads too?

His thinking may be that he reaches higher speeds more often due to the more powerful setup, and he needs to stop a heavier vehicle from these higher speeds, thus there is too much heat for the stock setup. Just guessing, that's why I asked him my question above.

What G-LOC pads are the guys running?

R18 I think.

To answer a few questions…it is mostly high speed decel where the brakes feel inadequate.

I need to correct my info on the brake fluid, it is Castro SRF. The only thing we have not done is run out the gy sc tires and swap over to sc r.

Part of our quandary Is coming from a 3000# c5 that had 620hp and a big brake kit that allowed it to go deep in the corners. The first thing noticeable with the ZL1 even when I first purchased it and it “only” was at 750 hp was how fat it felt compared to the Z06.

Yes, it handled better, but still was a chore to slow it down.

We probably do more straight line events with 1/4 mile and 1/2 mile as well as street driving, but all you guys saying the stock brakes are fine with just better pads and upgraded fluid are probably not making this kind of power.

The previous Z06 would run down the same straight at close to 150 before needing to brake and if we ran this car to the same spot we’d be at 170. It’s a big ole, overpowered girl.

I did have several guys at sema running in the optima street car challenge say they swapped over to the C7 carbon setup and that helped as well as a few manufactures said they would shoot us some info on their big brake setup.

I’m guessing we will not find something that is night and day difference like we did with the c5 wilwood big brake kit but it was quite an improvement.
