Clutch slipping, but only on highway? Heat issues?

I just recently drove to Tallahassee from tampa, about a 5 hour trip. Not driving fast, just cruising at about 2800-3000 RPMs.
5th gear, ease onto the throttle to pass and the clutch slips badly. So, continued cruising to tally being carefull not to get on the car hard. But for sure the clutch was slipping. Getting on the on-ramps was a bitch.

So, pissed off, I park the car when I get home and didn't drive it the entire weekend.
Needed to drive the car so, after a few days of being parked I took it out. No slipping. I put the car in 5th at about 20mph and still no slipping. WTF?!
I drove the car around for a few weeks, just normal everyday to and from school and no slipping, even under some beating/boosting

Then just this past weekend, I went on a cruise with the local car group, interstate cruising to Georgia, and once again, the clutch slips after some interstate driving. Once again, the driving wasn't fast, just 2800-3000k RPMs

I take the car out today, no slipping...:wtf:



Is this the clutch overheating while at high RPMs for a longer period of time?
any ideas would help, and is there a way to fix? or is a new clutch in line for me?

Could be heat but I am not sure though. The last time I hit the track I beat on my car for hours. Finally after like 30min-1 hour of straight drifting my clutch started slipping because I have been beating on it from clutch kicking. It has been 2 months and I have yet to see slipping again.

Oil may have passed by the rear main seal and somehow gotten onto the disk surface but thats doubtful unless your car leaks an immense amount of oil. Your car is turbo? I can't think of anything that could make your clutch slip like that besides oil.

I believe the conditions you've described are the first signs of clutch wear.

when my clutch started to go...that is exactly what happened. it first showed its face at WOT in 5th...and then maybe a month and a half a steady decline to the point where i can barely make the car move at 50km/h and it is almost impossible to get ti going from a stop.

you need a new clutch. you can make it last a bit longer by not letting it slip, but it will eventually just stop working...especially when you can't help but slip it.

ahh poo...yes, today it finally started slipping more. No highway driving now, just for sure slippage...


I'm going to baby it along as much as I can. No money for a clutch just yet... :(

I think i'm going to be going with the stock setup from CKanderson with the 6 puck disc
