fAfter my very first Autocross a guy in the PCA club sold me his extra set of forged lightweight 944 Turbo wheels with a new set of Goodyear R1s on them. Now those were race tires. Had just one groove around the tire the rest was slick. And yes they would pick up and throw stones.

Always went thru the routine of changing wheels/tires at home and drove to/from the autocross. Was driving them home from the race one day, as I was passing some people walking I about spun out. Think one of them spit on the street, LOL.

Another time I was driving home and the streets were damp. Didn't think I was going to make it. Couldn't safely go over 10mph.

After I wore the R1s out I went to Yokohama Wet race tires with the big but very few criss cross grooves. I liked them because you could still get some traction in a drift, the traction just kind of tapered off. They were what is called soft edged. The R1s just had gobs of traction until they had NONE, hard edged. It was like the difference between Bridgestone (soft edged) and Michelin (hard edged) in Formula 1 at the time.

When I got the 928GT is when I quit swapping tires for autocross. Lazy pit crew just put on the stickiest street tires they could find and called it good. Don't think the 928 was made to autocross. I've melted several pairs of front brake wear sensors, even with the GTS and the big 930 brakes.
