Slotted/Dimpled Brake Rotors

Does anyone have a source or spec on brake rotors? When I found my car it already had 59,800 miles on it. Someone had already done a brake job. I currently have slotted and drilled but I think this is incorrect from original, yes??

I don't have a 100% for sure answer but Matt installed slotted/drilled rotors on many cars.

It's possible your car could have had them from GMMG. Jim

Paperwork seems to match your rotors so I'd guess they are correct. Rotors last a long time so they could be original yet? Maybe someone else can add more info. Jim

Bobby.......................we rotated and balanced the tires today on the Tom Henry Racing Camaro SS that I just bought on May 1st, 2013 and as you can see.............my window sticker is similar to yours and my rotors are as well. This car only has 4,690 miles on it so I'm sure that these are the original rotors that Matt and the crew at GMMG installed on it when it was modified by them.

OK, Great. Thanks for solving the mystery. I thought I was going to have to chase some down.

when I had my car sent back to gmmg a couple years ago matt told me they used two different types one was drilled and slotted and the other original run was just dimpled. he said the dimpled rotors were just the stock rotors that he had someone machine dimples into. hope this helps as I am looking for a set as well.

thanks

If you want the original GMMG rotors that are ball milled I can get it done for you if you need them exactly correct.

Let me know.
