hey guys im a service advisor at a gm dealership , gm has slotted vented rotors for the ss for all you guys having pulse problems . i dont have the part numbers but i will post them next week for you guys , but im sure the parts dept. at your dealership can find them for you .
gotta love the car tho
the part # are 19158827
19158828
19158829
19158830

 

Thanks Pugs, I do not have any problems yet except for a little pulsating at a 80 klms break, my service adviser wants to give me these as well and a discount for my rears,only because they keep bugging me to let them mod up my car And who says the dealerships think negativly on this sort of thing

 

Hey Pugs are you at a dealership in Canada and where?

 

so if you tell your service guy that your breaks are pulsing there fix is to put the slotted and vented brakes on?

 

and this is covered under warranty?

 

I have already had mine replaced with the cross drilled and slotted GMPP rotors for free under warranty

 

anyone know the part numbers?

 

Which dealership was that done at? Ive been to mine (Don Howsen, Toronto) and they machine the rotors each time. Id much rather get different rotors. Any tips on the right words to get this done?

 

The part numbers are on another thread,Im just to lazy to find it( waiting for my first coffee of the day to brew)

 

the part numbers are confusing, i dont know which is for the stockers and which is for the gmpp.

 

How much milage did you have on your car when they did your rotars,my dealership Barnes Wheaton alreadt told me with the pulsating happening to bring them in and they will get me these

 

How does it look? does it make the rears look lame?

 

I had about 15000kms the first time and about 22000kms the second time (the pulsing started earlier but I didnt go straight away)

 

My pulsating is happening at a 8oklm break,they told me to come in, but I want to wait until I can afford the rears

 

Should I bring this up to my dealership and say "Listen, Ive been in twice already with this problem. I need a permanent fix. Can you put the GMPP cross drilled slotted rotors on?"

 

I would do this without a doubt, just find the thread with the correct parts numbers

 

All the part numbers are all over the web!

Well, I had mine cut tdown 3 times in the abck, and 4 times up front before my dealer would finally replace them ( over 7 months and 18K miles ) and I just don't see the advantage of the rotors being slotted, drilled etc...

ONLY of you're using organic pads since they actaully gas and then the slots help. The only thing those slots do are make your rotors wear quicker. I've talked to many guys that open track higher end cars ( vettes, porsches, vipers ) and they all say the same thing.

IF you guys run your cars hard and have drilled rotors... keep a lookout for stress cracks. Successive heating and cooling can cuase it and that's not good.

At any rate... good that the dealer is able to do that for you if you want it. Not all will.

Getting ready to replace my rotors again ( 33K miles in 11.5 months ) and it's hard to find a good rotor out there.

 

A dealership here in NJ called Rossi. No special words to use, just make sure your brakes are legitimately f*cked up. Don't go to a dealership looking for free rotors when yours are problem free

 

not really....I have the polished 17's so it hides them bit. People really have to look to even know I have the GMPP rotors on the fronts

 

Here is an actual thread of someone with a RL that has these rotors and his opinion on them:
