Ok, so I don't normally doublepost, but I'll do it just this once. I've changed the title, but other than that this is what I sent james.
The GTPlanet Forums: The Rolex Sports Car Series on Gran Turismo 5
The Rolex Sports Car Series is a motorsport event that was established in 2000 after taking over from previous events similar in their setup, and was originally under the Grand American Road Racing Championship name when it began. The series itself runs a mixture of racing prototype machines and Grand Touring specified sports cars over a series of different tracks across America, each being an endurance style format across roughly a three hour length, with the exception of Daytona Road Course, which is a 24-hour event. Using elements of this well known series as a base, members of the GTPlanet Forums, polarbear345 and james6653, have decided to create a racing series on Gran Turismo 5 that can be participated by any and all who are interested, regardless of skill level. Since the event is only a namesake of the original Rolex Series, it does have its own differences in structure, ruling and regulation aspects.
The basic layout of the GTPlanet Rolex Series is that there are eight different tracks, each of them having a set number of laps hoping to last within the duration of an hour and twenty minutes. The number of laps varies, depending on the length of the track itself and tested lap times set by the cars involved, though many of the races length are similar in distance. Each track chosen is a well renowned race course from around the world, but will include tracks mainly from North America, in an attempt to keep as close to the original series entirely American layout as possible. A total of 16 drivers can compete in the event, which is evenly split so that eight drivers race in the Daytona Prototype (DP) class, while eight race in the Grand Touring (GT) class.
The cars used in this series try to remain as close to the mark as possible, but on a game such as Gran Turismo 5, the use of the Daytona Prototypes is impossible, therefore Le Mans Prototypes are used instead. The Grand Touring class is comprised of a number of premium model sportscars that are tuned to racing specifications, and given aerodynamic parts to improve cornering and downforce. For the Daytona Prototype class, the Bentley Speed 8, Toyota GT-ONE and two Peugeot 908 (Team Oreca and Team Total) race cars are used. As for the Grand Touring class, the Audi R8 4.2 Quattro, the Ferrari 458 Italia, the Dodge Viper SRT10 and the Chevrolet Corvette Z06 are used for this event.
Rules and regulations play a big part to any racing event, and this is no exception. Rigorous testing has been applied to each and every car involved, with overwhelming feedback from many drivers. There were cars that originally were going to compete in the series, but could not keep up with the ever changing regulations, either through falling short of competitiveness, or failing to meet certain criteria. As it stands, the Daytona Prototype class has been issued with a weight limit of 970kg for all cars included in the class. However, their power limits have reflected testing, and thus the power limit has been set for around 580bhp, give or take, for each prototype, which is surprisingly good. The GT class has seen the most dramatic testing, and thus has the most dramatic settings of the series. Cars here have been set to a weight limit of 1280kg, while the power limits range from 460bhp, to as high as 510bhp.
