RTTH VII Rules/Ideas
1: What would the group think about "adjusting" the street tire treadwear rule from 200 to 180? Goodguys is using 180 in their rules, and this would open up some options for lower cost tires, especially the Kumho Ecsta XS. They have some really meaty sizes that would work well, and these tires aren't technically any stickier than any of the best 200's out there. SCCA uses 140 as their minimum rating, as anything on the market lower than that, at least that I'm familiar with, is considered an R-Compound. Except for Miatas running 140 Toyos, most of the winning tires in SCCA autocrosses are 180's and 200's.
I run the Kumho's on my RX-8, in addition to the 200 treadwear Dunlops, and though they don't offer quite the lateral grip of the Dunlops, they are far more tolerant of accelaration and hard braking. This would be beneficial to all the big V8's that have a lot of power to put down, and have huge brakes also in need of grippy tires to slow that powerhouse down.
The reason I ask is that one of the RTTH newcomers is about to buy his first set of extreme performance tires for his 2nd gen Camaro, and my honest recommendation to get the best bang for your buck would be the Kumhos. I think a lot of guys could benefit from the great performance, great tire size choices, and low comparative cost of these tires.
2: How about bringing back 2 driver cars? This can be accomplished fairly easy using any of the following:
A: Run the cars in 2 separate run groups, like Spectre did with their El Camino. The adhesive numbering that Bill came up with was great, easy to read, easy to peel off. When the first driver was done, the first set of numbers were removed, and the next driver applied his numbers for his run group.
B: This would be the method I would prefer: Use an SCCA style grid to line up the competitors, as opposed to the single file line that keeps feeding and moving. With a grid, once a car makes its run, it returns to its spot until the next run. Both drivers can run in the same group this way. You can peel and apply/reapply numbers, or have them both there, with one set covered up, or whatever. Simple details..... I can help with a grid setup next year.
Again, the reason I ask is because of that black 2nd gen Camaro. I am helping him with the car setup & tuning, and would like to drive that car next year instead of the RX-8. I drove it last weekend at an autocross event in Chattanooga. Horsepower is fun...
