Thanks. Very few rules in the GT class so we can pretty much do what we want.

We have 3 types of tire to choose from: Slicks, DOT <100TW, and DOT>100TW
Cars with slicks must run the most weight, less for <100TW, then even less for >100TW. I've chosen slicks, as does most everyone in the higher classes because the DOT's overheat on the higher HP/higher grip cars. We also have a great contingency program with Yokohama, which is why I have so many of their stickers on my car. Last race weekend, I won a full set of 4 valued at around $2k for my class wins.

Class with Slicks

GT1 less than 7.01 lbs/hp
GT2 7.01-9 lbs/hp
GT3 9.01-11.5 lbs/hp ** I ran 316rwhp and 2850lbs last race (restricted hp and added ballast)
GT4 11.51-14 lbs/hp
GT5 14.01-16.5 lbs/hp
GT6 above 16.5 lbs/hp

Weight is including driver and fuel and you must meet weight at any time during qualifying or the race. We always get weighed in after the race (top 3 finishers).

Only rules are:

-Car are limited to one wing (no front wings attached to the hood). Wings must be single element (no multi element wings). No active or in car adjustable aerodynamic devices.

-All engine swaps must be of the same manufacture.

-all tube frame cars must take the slick weight requirements

-maximum of 350lbs of ballast

-switchable ECU's must be declared, inspected, and explained
