Great! Remember, bigger tires require more of the car, weigh more and bind the car up faster. Don't get me wrong, they have their place. I used to run 265 in front and 295 in the rear. At a track like willowsprings, it was great due to the high speeds and corner grip needed. However, at buttonwillow and the streets of willow, they slowed me down due to the lower speed corners and technical turning done there. When I went down to a 245/265 set up, my times were jsut under 1.63 sec faster because the car was lighter and did not bind up as fast. My turn in was easier and faster. I know it sounds like a small amount, but some people spend thousands of $ and months trying to make up that kind of time. Another point to make is count the corners on the track you will be at. Loose 1/10th of a second at each corner on each lap and tell me how much faster you would be if you didn't. Now do the same thing but remove 1/10th. It should all make a litte more sense now. Small advantages add up corner after corner.
Oh, one more thing...study the course carefully. I do this before any event, even tracks I know. I also make sure I know what may have changed since I was there last. If you can, walk the track before the event. LOTS of good info out there if you look for it.
The falkens are cheapest at

Good Luck!
