i . i have 2007 corvette, ls2 but the rotor from factory are drill, so what size it is? in front and rear? and it is possible to upgrade the front?
thank
We need more info for sure.
The rotor sizes are as follows dependant upon the Option code of the vehicle (ie: Z51-Base-Z06)
You either have the Base or Z51 rotors.
Look at the Option code in the glove compartment and see if you have the Z51 RPO code.
Here are the rotor sizes.
C6 Rotor Diameters in inches
Base.....front 12.8 x 1.26 rear 12.0 x 1.0
Z51......front 13.4 x 1.26 rear 13.0 x 1.0
Z06......front 14.0 x 1.26 rear 13.4 x 1.0
ZR1.....front 15.5 x 1.42 rear 15.0 x 1.34

There is no such thing as Z51 brakes, since Z51 is an option code for a base C6 that happens to include the heavy duty brakes. The brake code is J55. Any '07 with factory J55 brakes could also have the Z51 code, the F55 code, or neither, since J55 brakes were also available as a stand-alone option. JL9 is the code for standard brakes.

If you change rotor sizes, you need to do it for both the front and the rear to maintain the correct braking balance. You can switch from JL9 standard brakes to J55 heavy duty brakes or vice versa, by swapping rotors and the respective brackets with causing a significant problem. However, the J56 brakes, used on the Z06 and Grand Sport require changing all 4 rotors and the calipers.

I'm terribly sorry for even mentioning Z51 in my reply for rotor sizes.
So basically, your saying that a Z51 Optioned car would have the J55 HD brakes. I do believe I did mention the Z51 RPO code which as you know, does include the F55 RPO HD brake code.
I would think that most members on this forum know exactly what I meant in my post. Most may not know that J55 are the same brakes as on a Z51 optioned car.
Have a great day

My point was that the OP, who posted his very first post, certainly had no knowledge about what brakes were available. He would have been confused if Z51 didn't show up on his code list, but still had the size you mentioned. It's important to have accurate information and descriptions, especially since the percentage of second hand C6 owners on the forum continues to increase. It's up to us older forum members to help the newbies learn when they ask questions.
Most simply stated is that JL9, J55, J56, & J57 are brake codes, not base, Z51, Z06, or ZR1. Without defining the brake codes, owners of Grand Sports or other cars with certain options, have no assurance what brakes the car had when it left the factory.
