I am nearly in possession of my C7 Z51.

We plan to autocross the car, and maybe do some road racing.

Are the cooling rings of any benefit?

Do they really make a difference?


Thanks

From what I've read and from people I've talked with, they act as a heat sink to help cool the rotors and help prevent warpping. I imagine they're there for a reason or GM wouldn't have included them.Could affect warranty on rotors.

If I'm on a track with few elevation changes and turns that are easy on brakes, I might consider leaving them off.

That said, have you looked at the prep you must do before and after track sessions. This could preclude many from tracking their C7.

Yup, fully prepared to do all that is required.
Been Road racing for quite a few years in our C5 and C6.

Thanks for the info re the cooling rings,
As you said, if GM didn't think they were useful/helpful, they wouldn't have
provided them.

If you are going to track the car I would highly recommend using the rings. I did not used them on a light track day and warped my rotors. Now I have been using them and my rotors have been fine. In fact I have kept them on during all street driving and have not notice any issue in doing that.

I'm getting true 2 piece rotors. Putting those rings on is a PITA.

NTMD8R

OK,
any hints/tips/thoughts....

1. To put them on

2. Just leave them on permanently

1. You can instal them without removing the rotors.

2. Mine have been on for 10 months with no ill effects.

No corrosion or rusting whatsoever?

The instructions that came with them were very specific about removing them for street use to avoid this. Hmmm.

*C7*

No corrosion, they look like new. I don't believe the manual mentioned what part or parts were supposed to corrode.

Even if they do corrode they probably don't corrode any worse than very expensive two piece rotors corrode. The only part of the two piece rotors that doesn't corrode is the aluminum hat which is pretty much hidden by the wheel. Why pay $300 for a two piece rotor replacement ring that will rust when you can settle for the OEM provided cooling ring that doesn't wear out.

OK, (I don't have my manual yet)....
so how do they install ? (considering I will probably leave them in place)

From what I understand the real reason that they tell you not to leave them on is so that they don't come loose. Since they are only held in place by the cables, the rings or cables could come loose over time and, if something came off while driving, it could be "bad".
