Mine has been holding up fine. The slave is starting to go but not the clutch itself. Have about 20 passes on it.

I've had mine for over 15000KMS. It is holding OK but I could smell a bit of burning clutch at the last drag outing about 2-3 weeks ago. I had BFG drag radials as well and kept on launching at about 4K.

I've got 18000km on my ls7 clutch and took it to the track last weekend. Held very well though I use street tires, I hot lapped it a few times with no issues. I'm worried about the 10 bolt as the ls7 was grabbing hard and I was wheel hopping a few times. I got 10 passes on it for the day, all the while facing a straight on 30km/h headwind.

Had you posted this last week you would've gotten a completely different response. I installed my LS7 clutch in the summer 06', held up very well for a good while. I prolly got around 40+ passes on it. This last weekend I got 1 run out of it and it was slipping down the track. Went to do my usual 2nd gear burnout on my 2nd run, got the tires wet and dumped it at 6k to burn out, no tire spin, clutch smoke only. =(

RAM Powergrip HD going in. I am only at 406rwhp, I tuned the suspension a bit to do some good weight transfer before this pass and also lowered tire pressure to about 15psi on the ET streets. I have added a cutout but that's about it. I let it cool down about 20 minutes between my first pass and that time. I didn't even run it, just backed it up after the burnout attempt and parked it.

I've had mine for almost a year now and it is doing fine. I just have a few bolt-ons and I have never taken it to the drag strip. With that said, it's held everything I have thrown at it with no problem and has a stock feel to it. I don't think it would be a good clutch for drag use, especially with slicks and hot lapping. I like curvy back roads and have really abused it in that respect with no problems.

Everything I have read says its a good street clutch, not good for the track. There is some good discussion on CF about this, and the posts by "Ranger" shows the issues quite well. They apparently glaze as soon as you hit them with some RPM.

I wouldn't recommend 5k clutch dumps with the ls7, it's a street clutch more than a drag clutch

Just to mention 2nd gear burnouts are harder on clutches since the tranny ratio is so much less.
