You're right Stan. I had run a fastest time of about 16.1 with 16 by 8 inch rims, mazda RX-7 rims to be exact, which are very light, and 225/50 tires which also wern't all that heavy. When I put the stock rims/tires back on I hit 15.8. It was a bit colder that night too, so I'd think the difference was at least 2/10ths of a second.

I noticed the power difference as soon as I put on the stock tires again,the car felt noticeably faster, and going to the drag strip proved it.

If you're going to drag race, stick with the stock RS rims and tires, I would say you can't beat them.

I'm still keeping the other setup for autocross, the handling is great with those rims and tires!
