Al36rx7 Posted May 27, 2019 Share Posted May 27, 2019 I run a car (Tube frame third gen RX7) in ST3 that was originally set up to run GT3 in the SCCA world. I use 15x7 rims and using canteliever bias ply slicks (only Goodyear and Hoosier make these) since the rims size / canteliever tires work around the clearances of suspension bits. I am in complete agreement with the previous comment that the folks on a DOT R-Compound tires come on almost immediately. (Maybe it's the driver, as in me), but I can lose a place at the beginning of the race. Then I spend the rest of the race trying to find a way to get around them after my tires create some heat. I does make for some good racing. Most of our races are sprint races. I don't see the non-DOT tires being a benefit in these races. Maybe a different NON-DOT factor for Enduros, but IMO, I don't thing the factor is off. Quote Link to comment Share on other sites More sharing options...
