Brake Cooling Rings

Hi, I just bought a new Z51 Corvette and when I was going through the goodies in the storage compartment (Cargo net, covers etc.) I found an unopened package saying GM Front Brake Cooing Rings. GM part no. 23484111.
The package contains what looks like 2 stainless steel rings with a roll of safety wire. The rings are drilled in a few locations. It says if there are no instructions (which of course, there aren't) to go on line and search the part number / instructions. So far I'm striking out ...anyone install these and if so, what is involved or can you point me to instructions? Thanks.

there is no need to put them on unless you are tracking the car. If fact GM recommends removing them once you go from the track back to the street. This is due to potential corrosion of the rotor from trapped moisture and dissimilar metals between the ring and the rotor. There are a few posters on this forum who leave the rings on for the season and have reported no issues.

The broader question is, what would happen if you don't put them on and go to the track?

It would depend on the driver, track, and their skill level. Ideally you need to have the center some what closed off, or at least vented at the hat so the air is being forced through the vanes of the rotor. Because of how they made that rotor, and no real forced air being sent to it, it just flows through the center and you loose a lot of cooling effect.

Beginners on track would probably not have an issue leaving them off.

Several new owners have asked this question after taking delivery of their Z51. The dealer should have covered this at delivery. Obviously, many of them don't.

Not likely the sales people understand unless they track their own cars. Same goes for the mechanics in the service department. If they aren't involved in that type of activity they just don't have a clue about the demands on the brakes. You should see their eyes when you take a cracked brake rotor in to show them what happens on a regular basis.
