Get the Yellows, you won't regret it.

I've had them on my '92 Teg for close to four years now. Without getting all technical I can say that next to good tires it was the best handling mod I've ever done.

The adjustability is nice to have. When the summer tires come off and the winters go on I dial the whole setup back to soft. Come summer, I can firm up the ride to coincide with improved road conditions. At the autocross I can set it up really tight.
