I am looking to swap out my rotors to a two piece rotor. Any suggestion on who makes a superior rotor??

Thanks -Nate

Nate, give me a call. I have a few suggestions on the rotors.

423-288-3881

The rotors on the SRT are huge, and heavy. They gotta go.

The World Challenge 2 piece rotor setup on the Comp Coupe is Brembo. And it's sweet.... and about 10 lbs less than a stock setup.

Janni, 10lbs is certainly a huge amount. Stop Tech is much less than that. This means they are lighter in the outermost region, as you can only lighten the hat section a small amount. They must be thinner inner walls. The diameter of the SRT rotor is a killer. It's diameter has to produce a huge amount of drag. The rears should have a good bit smaller in my opinion, unless you plan on some really high speed driving. Even the front could have lost an inch, and still had great stopping power. 14 inch rotors as heavy as these have to be hard to move and just as hard to stop.

StopTech is much less than what? The 10 pound difference? The stock one piece rotor? the 2 piece Brembo rotor?

The hat is a huge savings, as it's one piece of milled aluminum - the disk portion you want to be heavy enough to absorb / dissipate the heat and withstand the punishment of the pads.

Janni, the hat section is not a huge savings compared to the over all weight of the rotor. The diameter of the hat is no more than 6 or so inches, but in a way it's a good savings, but I can tell you this much, 1 pound off the rotor beond the hat section, throughout the 14 inch disc, would be more effective than the 3 pounds off the small hat section, roughly. Not just heavy are these rotors they are huge in diameter.

If proper material is used the disk portion could be lightened up. These rotors are just to big.

If your not tracking the car, we could get by on a much lighter, and smaller diameter rotor. We may risk warpage, under extreme conditions, but the car will still stop well. A bonus is gained in braking on small light rotors. This sort of counter effects the downgrade in brake size. Large heavy spinning objects take much energy to stop, due to momentum.

Has anyone noticed the diameter of the Z06 front and especially rear rotors. Extremely light weight, and small inertia factor, as it's at least a full two inches smaller in the rear. That's not a slow car, and it's doe's not have a poor brake system.

Bottom line, (4) 14 inch monster rotors that weigh a ton, is absolute death on accelleration.

Only is this boat anchre brake system exceeded in overkill, by the over weight oem rims on the car.

Oh, Janni, forgot your question. You said 10lbs savings on a Brembo, I asume you ment 10lbs each, and they must be much lighter in the disc section, because Stop Tech, is only about 7lbs lighter if memory serves me.

If you ment the complete set of rotors only saved 10lbs, and they are really high rated rotors, then they must be built for extreme continous speed, or they are a cheap upgrade ment to do fair, but lighten things up a bit. I'm sure there are rotors on the market that are very light weight, and built for extreme speed, but they are probably very expensive.

I think DC is worried about us having one to many high speed shut-downs, and warping rotors. This over weighted rotor probably didn't cost them much to make, and insures them from replacing rotors by the thousands. Check out the stopping distance of a Z06 at 80 to 0 very impressive

I'm sure there are lighter rotors out there.

I wonder if they would have the same, fade-resistant, stopping power as the big stock rotors. I love it that the stock rotors can soak up so much heat, and still keep stopping the car. I worry that an ultralight rotor might not have enough mass to absorb the heat from a long track session.

I agree that the stock rotors seem like overkill, but you can't argue with the fact that the SRT-10 has amazing braking performance, and that this performance is consistent lap after lap at the track.

I'd love to go with a lighter rotor, but I'm afraid I would give up quite a bit on performance.

I think that a carbon ceramic rotor would likely give light weight and high performance, but I wonder about other ultra-light solutions.

Kai, good point.

Tracking the car doe's require a heavy large rotor, or an expensive lighter rotor, but the lighten up the disc, and not have fade or warpage, big money has to be spent.
