Ordered a set of 205/50/15 RA-1's, shaved, and a new set of R-888's, also shaved to compare this weekend. I will get Traqmate data from a couple different drivers on them to compare. We have a 3 race weekend starting tomorrow, so we should get some good data.
I have not shaved R-888's in the past, but wanted to give both tires their best shot, and since the R-888's are heat cycling out anyway before the rubber is gone anyway, I will probably not lose much usable life in any case.
Our set-ups are optimized for R-888's now, but a narrower tire on the same rim should have less dynamic camber loss anyway, so it shouldn't be far off for this tire. Supposed to be in the mid-90's temperature, so it will be interesting to see how the tires compare later in the race.
I will post results in a new thread.
Joel, I take it from your comments that you would not object to your money in the Toyo Kitty being used for this. Andy, Ray & I have all thrown Toyo bucks into this - we need to get a handle on the tire issue!
