Basicly, this is street drag on ssr7, and the question is which setups are good for these type of racing, and that is the features thats in gt5. I dont speak about tuning the cars like real drag racing cars, but cars that actually will accelerate faster etc on straight line in the game. 1/4 is bull in gt5, because if one car has just a little bit better traction and jump the line, it will be half the way on 1/4 mile, when you still spinning tyres in the beggining. The only thing that can prove which car is faster is 2 miles ssr7, then cars have the chanse to pass you.
Lets take a 700 hp zr1 in this example it has amazing traction compared to a 700 hp supra, which has horrible traction with wheelspin. Why? because the tires are wider on the zr1 and give more traction. But in real life, we know that a 700 hp supra wouldnt run tock size tires. And in a real drag strip, it eould probably beat the zr1 anyways.
Once again, try to apply real life drag physics to gt5 which hasnt got drag physics is questionable. I run setups whic are the oposite of traction, like low car, stiff springs etc, and they do well in the ssr7 drag.
Im reallty glad though that "street drag" was invented by the gt5 players, because it is fun. I dont mind that there arent a real drag strip, because 1/4 mile is way to short for me, i like top speed long straights. Just look at förza 3, they have a drag strip, but it is useless because forza havent got drag physics.
