Thats kind of what i suspected and respect your experience there.
however, ill probably never run slicks on my car, unless the entire suspension is redone.
. fortunately, all we run out here is the DOT class races.

Mark, I'll help you with your dilemma. 1st out lap, Hoosiers will be faster. 2nd and subsequent laps, any slick will be faster. I have many years of time trialing under my belt to substantiate this general statement.
I will qualify this by asking what your point is? If it is for racing, then the above is usually true. If it is for time-trialing, then it is absolutely true because you should start your pressures a little higher as they will not build as much in 3 laps, so the slick is up to pressure even quicker than in a racing situation.

You mean March 2008. When was the last time you ran RA1's anyways?

Another 8 months of RA1 use showed me I was wrong.

Not at all. Just working on a deal for some Kumhos, that's all. Trying to find someone with comparative experience. They were only mentioned once on this thread but I don't think the refrence was to the raciing slicks.

Just an on going set of data points regarding the comparisons we have been discussing.
We finally have a car that is driven by a good, consistant driver and running both slicks and hoosiers R6s, new sets on a consistant race to race basis. He is running in the SP SCCA group and the DOT clad ITE group.
This weekend, he was consistantly 1-2 seconds faster on the slicks, all other things being equal. (for the most part) 1:30.1 for the SP race, 1:32.9 for the ITE race. 1:31.1 for qual SP, 1:32.1 for ITE on DOTs. This is on a 600hp NSX turbo. Same days for both qual and the races in each of the two run groups.
Now getting back to the Toyos vs Hoosiers, I certainly wouldnt bet any money that he couldnt run within 1 second of the DOT race time of 1:32.9 (i.e. 1:33.9) on a toyo RA1 or R888. 275rears with 225 fronts.

The R6's vs slicks makes sense as many of the SCCA guys run A6's at nationals and say they are 1-2 seconds faster than the R6's and that many full slicks are hardly faster than the A6's at all.
