Don't have these so can't comment on if they are the best or not, but Coleman Racing has 2 pc. rotors
14" diameter rotor is correct for 2006-2013 C6 Z06 & GrandSport Corvette only. Each rotor weighs 16.25lbs - a weight savings of over 10lbs per rotor.

These rear rotors weigh in at 14.25 lbs. each compared to 20.5 lbs. to a stock rotor. That is a weight savings of 6.25 lbs per rotor.

Default Need ZO6 / GS Rotors Blueprints...

I called Coleman racing and Larry told me they don't stock any rotor as they are spacial order only and the only way to order is ether send them one of each front and rear as the one on my car or sent them the dimensional blueprints.

If some one could help with the exact measurements please e mail to davidllerena12@gmail.com

I don't want to try it myself and find out mega hundred dollars later that i screw up lol.

Sooooo, you're gonna trust us instead??

Seriously, anyone can go to several websites for stock OEM rotor dimensions, and if Coleman is serious about selling you a set, they should gladly do it for you.

seriously? this guy and most it would seem CF subscribers can't google anything, or search or make up their own minds, they want to be told what to do ,how to do it, what to buy and then whine and cry when someone points that out or they don't get 25 hp when they put a vararam on.

I find it hard to believe Coleman has never made a set of rotors for a C6 GS or doesn't readily have stock rotor dimensions on hand for a variety of vehicles.

Here are 2 good brands, and the ones I look at the most but have yet to convince myself to buy them since I don't need brakes yet.

http://shop.performanceafx.com/C6-Z06_c14.htm

http://www.racingbrake.com/category-s/7301.htm

You may have to contact them to get actual weights.

The performance AFK are coleman rotors. Tons of people have them and have been running them for years.

Racing brake or coleman are good. Not sure if LG still has their but they are top notch too.

That sounds like a silly excuse. Make one and all the dimensions are saved in the computer.

Default 2 piece rotors

Hi:
ZIP products www.Zip-corvette.com 1 800 962 9632 sells two piece rotors for the C6 Z06 and Grand Sport as Grimlock states above.
These are made with Coleman Rotors for Zip products .
I do not know where Coleman can say the do not know the dimensions but they also would not normally admit to doing custom work for someone else !
Part numbers are:
DB749 Slotted $759.95 for the fronts
DB846 Drilled $859.95

DB845 Drilled with park brake provision $899.95
DB775 Slotted with above $799.95

I have the slotted rotors on my car front and rear and the work
great , just like stock rotors.
Hope this helps
Ed

Thanks Ed we have an account with Coleman problem is we don't have the prints for the zo6 / grand sport.

We have order for other cars and got the prints from other fellow racers who had them but we need for corvette.

3D laser scans perhaps? They are extremely accurate and quick, but not free

Coleman makes the rotors, not the hats. The Zip or AFX rotors use coleman rotors with their hats. That is probably why coleman is saying that. Just buy from zip or AFX. Done, just like hundreds of others. You are making this harder than needed.
