they are not zinc dipped and will show rust (if that's important to the thread originator).

just as a FYI
Here is direct quote from Tirerack
"IMPORTANT REMINDER: Slotted, drilled or dimpled rotors offered as OEM replacements should not be considered appropriate for high-speed track use.
While grooved, drilled and slotted rotors offer an enhanced appearance and add some resistance to the boundary layer of gasses that can build up between the pad and rotor, they are not designed to withstand the extreme temperatures that are produced on the racetrack. If they are used on the track, it is very important that the rotors be carefully inspected and should not be driven on if even minor signs of deterioration are seen. Note, too, that if any products are used on the track they are not warrantable."
Here is a quote from S2K website
"A few words about drilled/slotted rotors… These are supposed to make your brakes more effective because they presumably cool better than solid rotors. While this is probably somewhat true, these should almost never be used in performance applications. A drilled rotor is a weakened rotor and is much more likely to crack under high temperature conditions. The holes also reduce the surface space for the pads to make contact with and therefore reduce friction. (stopping power) While slotted rotors are definitely stronger than their drilled counterparts, they too offer the disadvantage of reduced surface area and therefore less stopping power. For high performance/racing applications, solid OEM rotors will stop you as well or better than just about anything out there.

I put mine on last winter....after painting the hats and the outer edge of the rotors. I rec'd mine in about 2 weeks a year ago when I actually
bought them from GMparts. I also got the A/C Delco ceramic pads too.
I love the whole combination for cruisin' and the occasional mountain run. I don't race.

Just Installed them
Just had them installed. I painted hats with 1200 degree. then baked between coats on my asphalt driveway. Placed them on an aluminum backed insulation. Temperature got to 160 here in N.J. Pictures show where rust develops immediately., golden rings. So if you wish to avoid rust, paint the hats. I painted entire hat also where wheel mounts to hat.
Good price but do paint them if this means anything to you. P.S> before you put them on the car. I also went with ceramic pads.

I painted the original stock ones after they started to rust. I will paint the new ones. I couldnt find the part # for the stock rotors on GM parts Direct? Anyone have it and the price?

Nice bling but the suck because of the rust. I taped and painted the hats but did not tape far enough up onto the rotor so ther is a rust band between the hat and edge of the pad. Also the outside edge and vent area rusts. I woud not get them again.

Hello, copy and paste this. it is from Ebay. I have purchased a few of these sets and they have been great. Just make sure you purchase from someone with a good feeback. Go to Ebay motors go to the bottom to corvettes click it and go to the bottom right and click C5 parts.
I'm not sure if the URL worked......this is the item # 290010733938

Wicked Weasel:
Do you think everyone who owns a C6 should chage to solid rotors before taking it on a track or do you think GM nows what they are doing?
I would not recommend the swiss cheese rotors but a few of us with drilled and slotted GM rotors and PFC Z-rated pads have used them at track events with no problems, and in my opinion they do stop better on the road and on the track.
