Since I'm an instructor at TWS, I've ridden in and driven a LOT of different kinds of cars on the track.
Leather seats are the worst, especially of the owner has cared for them by slathering them with some kind of leather conditioner. Very slippery.
Vinyl is almost as bad -- though the hotter it gets, the grippier it gets. The fact that most real vinyl seating is found on '60's and 70's seats with no lateral support doesn't help things though.
"Pleather" (artificial leather,) is about the same as vinyl.
Cloth is by far the best for keeping your butt where its supposed to be.
But the most important thing is to get a set that has real lateral support. Unfortunately, that pretty much means a racing seat. OEM seats and aftermarket street seats can be an improvement over stock seats in many cases, but they pale to a real racing seat. I have an Ultrashield road racing seat. You pretty much have to wedge yourself into the thing, but once you're in, you don't have to worry about staying in place. Between the seat and the harness, nothing's going anywhere.
Oh -- and the seating material on the Ultrashield seats is user-replaceable. It just snaps into place. Wear it out? Buy another seat cover and install it in 5 minutes.
