I have been autocrossing my 74/2.0 for quite some time, but last week, I joined the BMW club at a driving school using 10 year old tires. I spun a lot, but the problem is that everytime I spun, there was a lot of smoke but no leaks and the gas pedal would stick until I shut the car off. Any idea why this would be happening? After 5 spins, they told me that I had to get new tires or I can't be on the track anymore I think they were afraid of being embarassed!

did you spin the motor backwards?

It is interesting that you say that because even though I was in a forward gear, the car wanted to go in reverse. However, once I shut it off and restarted, I was fine.

Who let you on a track with ten year old tires?

gears don't matter ...

if you spin and go backwards and you don't put the clutch in, the tires will *force* your engine to spin backwards ...

there's the old saying: "if you spin, both feet in" (that would be the clutch and the brake) ...

Thanks for the explanation. That makes a lot of sense. The instructor kept saying that when we spun, but I did not have both feet in right away.

To get your car to stop spinning DON'T LIFT THE GAS PEDAL IN A TURN. Unless you are trying to use throttle lift oversteer to get the car to rotate.

and get new tires.
