as long as it is 2700lb or less it is a WIN with this car.
S2000 is about 2700lb with convertible roof.
Its not as much about HP/weight ratio as lateral g load on tires and chassis stiffness when talking about Track Time Attack.
Look at the GTR for example. There was an interview with the GTR designer. His ORIGINAL goal, according to the interview was to make the car have a certain size tire contact patch, match with 3800lb. Somehow he got the idea from F1 cars to determine how much the car is suppose to weigh, and he understands that under downforce the F1 car weighs "that much". His plan works extremely well with daily driving in all conditions. However, it sucks for track usage because of the tire load without downforce and tire load WITH downforce under lateral g forces.
In conclusion, if the car had a naturally smaller "package", the car would not require huge brakes , which means the car can use smaller rims, as well as smaller tires. Naturally this should translate to smaller $$$ in producing the car because of less parts used.
