CHEAP R888s, 205/50/15

Now that I've ordered my set, I'll let you kids in on this one.

$79.99 each - nice.

That's a good price, but I got a set of used 888s last year shipped to my door for the price of one of those, not shipped...

You want inexpensive race tires, usually better than described: USDRRT on ebay... by going used you can try out lots of different tires until you find one that works best with your combo/setup. It's one method for us on a budget to get lots of cross-tire tryouts...
