So about 6 or so months ago I got a brand new clutch and flywheel resurfaced.
All oem. My shop said it had the original clutch from when the car was bought. (04 with 110k at the time) Which was pretty impressive. The oem clutch discs are also known to last upwards of 60k miles on normal DD

Ive noticed a few times recently that if i were to turn a corner and hit the gas my back end would raise slightly and my RPMs would shoot up and then catch down low again. (thinking the back end was kicking out) but never herd tire squeal and never saw noticeable smoke from my mirrors.

Now im going into thought that my clutch is slipping.

I havent even put 5k miles on the clutch since Ive gotten it replaced. and yes I know how to drive stick for the few that would think that.

How would I be able to diagnose if it is a clutch problem. and what would be the cause of it to start slipping if that is the case?

 

yes the clutch is slipping. Recently my buddy with a gti got a stage 2 clutch put in and after about 2k miles the clutch slipped. Dealership says it was put in wrong. I would say get your money back from whoever installed it or call the manufacture and tell them what is going on.

 

That's just plain wrong. If the revs increase only when exiting a corner, why would that be the clutch? One wheel is spinning, and of the OP is expecting smoke from the tire(s), then he's been smoking something else beside tires.

To test for a slipping clutch, put the car in a high gear, and accelerate hard on a straight smooth road (up a hill ie even better). If the revs rise with the car not accelerating, the clutch is slipping. OP might want to buy a better LSD, or change his driving techique.

 

So thats my question....what else could it be?....
LSD is later down the road, but have to suffice with an open diff for now :/

 

And, there's your problem.

 

Peg leg burnout.

 

So it is my tire(s) ?
even though I cant see any rubber on the pavement or smoke?

 

If it was clutch, the engine speed wouldn't come down, it would keep increasing until rev limit.

 

The inside tire is spinning because it's loaded with less of the car's weight than the outside tire, so it has a lot less traction. You're really not going to see a big black mark or tire smoke from a tire under those conditions.

With an open diff the tire with the least traction gets the most torque (opposite from an LSD), so you can imagine how much quicker you'd accelerate out of a corner if the other tire (with traction) was getting that power.
