... to my eternal question about whether or not I should get DOT race rubber instead of good street skins.
Dat was in at Burnaby Kawi the other day and I had a chance to chat with him and Manny that has past race experience.
For some time I've been looking for a definitive answer as to just how long race rubber lasts and if they stabilize at a level of grip that's higher or lower than street tires after a dozen or so heat cycles. Bear in mind that I'm looking at the loooonnng picture here. Certainly race rubber is way better than street rubber at first and for a fair number of sessions after. But, I gather, at around 10 or 12 heat cycles the race rubber gets to the point where it is no better than street rubber but still retains that "I got it, I got it, I got-WHOOPS" edge that race rubber has.
There's another factor to consider also. I get race rubher and go out for a couple of sessions. Great, I learn to ride more aggresively thanks to my new found grip. But after a track day or two my advancing skills that are trusting the grip of the race rubber meet up with the falling ultimate grip level of the tires as they age through heat cycles. Result?..... I'd rather not consider that
Bear in mind I'm not doing this for fame, glory or money so I have no intention of buying tire warmers that would solve this problem.
On top of that I had super results with my D207's last season in that they telegraphed VERY well when I did something stupid and later, when I got faster and and did stupid things less often, did a great job of telling me when I was getting close to their limit.
However I AM on the ragged edge with street tires. I've noticed during the last few days where I'd gotten quicker that the tires were getting slippy at the end of the sessions. I'm thinking I could slow or limit the temperature buildup in the tires by going a couple of pounds higher in air pressure. With trials, small increments and copious notes of course. I'm particularly worried about the higher speed tracks like Pacific and Portland where I feel the tires will build up heat quicker and to higher levels in the higher speed corners.
So, all you race/track folks out there. Am I all wet? Did I miss something here? Is there a track tire that works better than street skins over the long haul?
Race takeoffs from the faster guys isn't an option in my case I'm afraid or I could change the tires after every weekend. My F2 uses a 160 rear which is extinct among the current top class racers. So I either buy new and buy often and be broke or limit myself to street rubber as I see it.
I'm still open to suggestons. The above is what I know at this point but it's still very sketchy.
Please don't get me wrong here. I had a blast last year on the street rubber. I did things I had no idea were in me. If I didn't get any better than I am now I'd be exstatic. But I know from the last sessions that I've still got further to go even on street rubber.
Any and all thoughts from the more experienced among this fine group are appreciated.
Dang this is a long one. Hope I didn't ramble too much....
