I appreciate the tips in this thread. I, too, am noticing traction problems, which I know are going to be a headache when I add the A2A kit later this year.

My biggest beef with my car is the gearbox. Gears are simply too short. I haven't done a lot of stoplight madness, but the times when I have, 7500 just comes WAY too quick in 2nd, and if I make the choice to pop into 3rd, at that speed, I'm already at 4500-5000 with not much room before 4th. 99% of the time I go from 2nd to 4th, and am getting quicker with it, but you just shouldn't have to play this kind of shifting game with a performance car.

I kept up with an older Audi TTS the other day, and while I know he has that (in)famous dual-clutch system, I was pushing the RPMs a bit too hard for comfort.

I had my car dynoed after the exhaust upgrade, and I'm at 312/269. I was hoping that the Michelins would reduce the traction control issues, and while I haven't noticed any fuel cutoff episodes like with the Potenzas, the light will still come on in 3rd accelerating out of corners. I don't want to be constantly replacing the rears...not only because of the cost...but because the owner of the speed shop who did it said he NEVER wants to change the tires again -- each rear took him three hours!

I suppose the best compromise is a diff upgrade, but I don't know enough about this sort of thing. Are there issues with speedometer accuracy? For those who have done this, what ratio is recommended? What speeds would the shift points move to?

Thanks!
