A new class will be run in group 4 at round 4. This is STU (Street touring
Unlimited). Here are the rules:
STU will follow the STX rule set, but will raise the displacement limit for
otherwise STX-legal vehicles to 3.1 liters for forced induction and to
unlimited displacement for natural aspiration. To accommodate the greater
power of these vehicles, restrictions on wheel width are lifted and the
maximum tire width will be increased to 275 for front or rear wheel drive
vehicles (but will remain at 245 for AWD vehicles). Other than these limited
exceptions, the STX rule set as described in 14.11 applies. This class
extends the Street Touring concept to cars including the Audi S4, BMW M3
(E36), Chevrolet Camaro, Dodge Neon SRT-4, Ford Mustang, Mazda RX-8,
Mitsubishi Lancer Evo 8, Pontiac Firebird, Pontiac GTO, Subaru WRX STi,
Volvo S60 R, and Toyota Supra. Excluded vehicles include the E46 M3 and the
E39 M5. In conjunction with the planned evolution of this category and of
the sport as a whole, these two supplemental classes will not be considered
for full national status until 2007. One or both classes could then
potentially be recommended for full national status provided that rules
stability is attained, member participation is strong, and the classes
continue to reflect the needs of the current enthusiast market.
