The purpose of the Super Taikyu (Super Endurance) series is to demonstrate the speed and durability of, what are essentially road going vehicles. Divided into five classes, the goal of Super Taikyu from a competition standpoint is to allow racers the ability to always race. Whether the car-driver combination is competitive with those in its class is not the sole concern. In Taikyu there has always been a blend of the five classes to allow for cars that might have slower drivers, or which are built to a slower specification, to have competition. Similarly skilled drivers or quicker cars generally have a class above to race with. ST2-ST4 cars find themselves racing amongst one another, whereas ST1 and ST5 are more traditional classes, meaning, certainly in the case of ST1, they usually compete amongst themselves only. ST1 cars are purpose built, FIA GT3 styled racing machines, which provide close racing action. ST5, the other “traditional” class, are FIA Super 2000 based touring cars, which by nature, provide close competitive racing in the slowest Taikyu environment. ST2-ST4 are showroom stock racing machines with minimal modifications to allow them to perform on a racing circuit and at the same time be safe. Because of the limits on ST2-ST4 modifications, the result is mixed class racing.
ST1: Cars with engines 3501cc and greater. Production derived, full fledged racing machines. Drive train is open. Forced induction is legal if factory stock, or in an attempt to equalize the cars. For our purposes (as the following cannot be changed in GT4), driver position, engine location and drive must remain stock. Engine capacity may be increased to allow for cars to enter the class (e.g. Nissan Skyline.)
ST2: Cars with engines 2001cc-3500cc. Modified production cars. Cars must be 4WD and equipped with forced induction from the factory. The following must remain stock, driver position, engine location, drive train and engine capacity.
ST3: Cars with engines 2001cc-3500cc. Modified production cars. FWD and RWD are welcome. Engines must remain in stock position but rear, middle and front engine configurations are legal. Four wheel drive (4WD or AWD) is legal so long as the car does not use forced induction.
ST4: Cars with 2001cc and less. Modified production cars. Must be front wheel drive(FWD). Engine position must remain stock. Front engine-front wheel drive configuration is mandatory.
ST5: Cars with 2001cc and less. Modified production cars. FWD and RWD are welcome. Engines must remain in stock position and only front engine configuration is legal.
ST1-ST5 All Superchargers, N/A Stages and Turbo Stages are legal. Assuming of course the competitor stays within the horsepower range for the given class and, at it’s very fastest the car makes lap times in the given range. For cars that COME WITH TURBOS FROM THE FACTORY, intercoolers are open.
ST1-ST5 Forced induction (turbo chargers / super chargers) are to be installed on factory N/A cars ONLY to equalize performance. In that event, NO INTERCOOLER MAY BE INSTALLED!
ST1 Cars must use Exhaust & Air Filer: Racing.
ST2 Cars must use Exhaust & Air Filter: Sports.
ST3, ST4 Cars may use Sports or Sports exhausts. I.e. ST3, ST4 may not use Racing exhausts.
ST5 Cars must use Exhaust & Air Filter: Street.
*Do to the heavy restrictions on tuning, yet the comparative openness for competitors to construct cars, cars will be tuned differently to produce similar results. If your car cannot match up because of a serious deficiency of horsepower and one cannot use forced induction or complete an N/A tuning stage, PM one of the race directors for help.
Transmission and Drive train:
Transmissions for ST1, ST3, and ST4 are open.
ST2, ST5 must use stock transmission.
ST1-ST5 All drive train components, Clutch, Flywheel, and LSD’s are open. LSD is restricted slightly to 1-way, 1.5-way and 2-way.
*Cars that are unable to install LSD, e.g. Toyota Chaser, can use level of 1 on the TCS scale if the competitor deems it necessary.
Racing brakes must be used in ST1.
Classes ST2-ST5: racing brakes are illegal.
All cars ST1-ST5 that are able to install a wing in Forza 3, must have a wing. Type of wing used is open.
ST1-ST5 MUST use a roll cage.
Weight reduction options are limited. All cars ST1, ST3-ST5 will be built to certain kg (as well as horsepower) standards outlined on the car list.
ST2 class vehicles may perform weight reduction stage 1 as class rules dictate a certain, very particular similarity to their road going brothers.
Full Customize Suspensions must be used ST1-ST4.
ST5 may use either Sports or Semi-Racing Suspensions.
ST1-ST5 A racing slick tire must be used. The tires will be chosen depending on the event. Each race thread will show it's coordinating week's tire.
Car list, Weight restrictions, Tracks, Points and Prizes to be announced later this week.
