Does this look toasted?

I'm going to replace the Clutch and Flywheel in the CTS-V this fall (~70lbs of dual mass junk) with a LS7 Flywheel and clutch kit.

I came across a "8K mile" setup in CL for a couple hundies . . .

Does this look like it was beat to death?

LOL... Might as well listed it as having been leisurely ran about the 24hrs of Daytona.....

looks like it was owned by a little old lady who only took it out on sundays to go to churce... slipping the clutch the whole way there and back

my typos aren't bad enough

hahah it boggles the mind that people can think that is sellable.

Anything is sellable, but someone with half a brain wouldnt buy it.

Used clutches are a gamble. They are not super fun to get to, and why was it pulled in the first place? With a new OEM LS7 clutch running under $500 complete with flywheel, thats a tough deal to pass up.

That being said, I put a used clutch into my Corvette. It was the only way I could afford something as awesome as a Spec Street Twin which usually sells for around $1300+. It was very very lightly used and the seller represented it well. He was pulling it out of his Z06 to switch it to automatic to make it faster at the track.

8,000 miles done a 1/4 mile at a time!!!

I put a viggen clutch in my old NG900.. when I pulled the car to the yard it was still in there with about a thousand miles on it.. I did not even want to think about tearing that car apart one more time

Honestly, I've seen a lot worse.

You guys are awesome!! I'm clutch/flywheel ignorant when it comes to what a bad, used one looks like . . .

Finally heard from the seller . . .

"I replaced it with a monster stage 2. I wanted something a little more aggressive if I went to the drag strip."

Based on the consensus here (and the sellers response) . . . a pass is the best option.

yes.. sounds like he discovered the hard way (on the clutch) that he needed something more powerful

8,000 miles is 32,000 passes!

Yeah, we're looking at the discolorations on the pressure plate & flywheel, and the shiny spots on the friction surface. Any time metal is treated to too much heat, it can change color. Any time a friction surface gets too much heat, it glazes like clay in a kiln.

I personally think there's no "if" in the equation about going to the drag strip in this case..that one's been there.

It's obviously well-used, but certainly not used up. I don't see any heat cracking, just plain old wear. I've seen similar wear on my clutches when I pulled the tranny for repair and pulled apart the clutch for inspection.

If the backside of the clutch disk looks like the photo of the clutch disk you posted, I'd use it no problems. From what I see in those photos I see a clutch that has 50% or more of its useful life left in it.

I would hit the metal contact surfaces with 400 grit sandpaper to take off the glaze and take a good look for any cracks. But if no surface cracking is present I'd say it's a good to run clutch.

It may be useable, but I agree with the sentiment of doing it right if you're going through all the trouble. I'd put used clutches in my beater Subarus multiple times, but I could pull the engine in 40 minutes on those - and I'd never put a used clutch in anything close to high performance, let alone a CTS-V! The wear on that pressure plate & flywheel is pretty bizarre, looks like it got SUPER hot at one point (as noted before).

Looks like one of those guys who can "drive stick" by slipping the hell out of the clutch to make up for his complete lack of ability to rev match.

Meh, throw a copper puck disk in there and it'll smooth everything right out.

Give that to the Team Turbo Schnitzel guys, they will think they have died and gone to clutch heaven.

Team Turbo Schnitzel: Complete with homemade lederhosen and a specially-hired paddock bratwurst cook, the Schnitzels also weren't short on mechanical ingenuity. When their Merkur XR4Ti's clutch took a dump, they made a new disc from sheetmetal and old brake pads. They scored an Organizer's Choice for all of their efforts.

I hav seen worse, but not on a vehicle the moved under its own power.

If I had found that thing laying around for free at a shop somewhere, I would absolutely try it.

OTOH, if someone was trying to get me to pay a couple of hundred for it, I'd skip it. Not flaming you, just asking you to remember how much "sweat equity" is involved in installing a clutch.
