I won't matter to much. Maybe in the faster speeds, but not enough to bother anything.
If you are just starting out ... I would say find a good medium sticky Summer tire that's good for the daily drive. When you come to a point where you want to start better competing then look for separate wheels and tires to run strictly for the races.
For somewhat sticky tires and good on the road ... I like my Yokohoma S.Drives. If you are looking at price. Check out TireRack first then if you want them soon, take the quote from TireRack and walk into a Discount Tire. They will match the price, if you don't want to wait for shipping.
