Z51 Rotor Question
I need to do my front brakes. 05 Z51. I'm looking for any option. Has anyone tried these.
CENTRIC Part # 12862086L SportStop Drilled Brake Rotor
Z51 Package; Front Left

CENTRIC Part # 12862086R SportStop Drilled Brake Rotor
Z51 Package; Front Right
$102.79
This is from rockauto.com. Goto brake rotors - at the bottom.
We know that GM only has one part number for the front rotors. One side of the brake rotor is spinning the wrong way and decreasing cooling efficiency (I can't remember which side).
My big question is if these are two different models or castings, i.e. one made for the right and one made for the left side. They do have different part numbers. If this is the case case, then the price isn't bad for specific left and right rotors.
Does anyone have any experience with these? I've searched. Thanks.

Just FYI, I have used these on my 07 Z51 and like them a lot, they are lite and last a long time. http://shop.performanceafx.com/C6-Z51-Corvette_c15.htm
Good Luck!

How many miles do you have on your car? If the rotors aren't scored or less than the minimum thickness required why replace them? For street use with OEM pads the rotors usually last as long as it takes to wear out a couple of sets of pads. Driving on the street you will not see any differences if the rotors are curved the correct way or not. Most track drivers don't see a difference.

But, that leads to two more questions, is the min thickness printed on the rotor? Can you turn/grind the drilled rotors like a blank one? Thanks everyone.

Unless your rotors are badly grooved or warped you don't need to turn them. Just clean them up with some sandpaper and install the new pads. I have an 06 Z51 and replaced my pads with ceramiks at 20K miles; didn't do anything to the rotors, just wiped en down. They are going great after about 15K miles.

The rotor discard thickness is in the Service Manual.
The service manual doesn't differentiate between any of the rotors on different models as far as runout, thickness variation, etc., and it says

Personally, I wouldn't consider "turning" or "cutting" rotors - I'd just get new ones if they're bad enough so that might even be necessary. The only reason that might be remotely necessary is if there are huge grooves on the rotor surface, but if they're that bad I'd just get new rotors.Rotor Discard Thickness Front - 30.3 mm / 1.19 inches

Make sure the guy that turns drilled rotors has experience doing them. The procedure is different than with plain rotors.
