But I am not >ruling out a street tire for the Kosei's and a track tire on the stock >basketweaves. Run street tires and track tires but reverse your rim choice. Run 15x7 Koseis with 225/50-15 track tires, I'd strongly recommend the Toyo RA1. If you've been running street tires in the instructor group then the RA1s will be a nice upgrade. The Toyo RA1 is very predictable and it makes lots of noise so it'll give you similar feedback as a street tire just tons more grip. They also have lots of tread so you can probably get away with driving them to and from the track while they still have tread left. After that they start to wear they get even faster! :-) I love that tire. The ones I'm using are pretty old so in the rain they weren't great but a fresh set probably makes for a nice rain tire. I take back everything bad I had to say about RA1s. Ben's new motto for Kumho.... Kuhmo!

Kuhmo! Way too slow! ;-) note that this was said relative to racing on Kumho's vs new Hoosiers. I think that the V700 or Ecsta V700 R-compound Kumho's are faster than RA-1's but their shorter life doesn't make it a good proposistion money-wise for a non-racer.

If the latter, the gap is all over on one side, thus 1 inch. Still, one little typo and that thing ain't gonna hold pressure for long. Scott >Date: Thu, 19 Jun 2003 22:12:58 -0400 >From: "C.
