Have you ever driven a car with power? I just did my first full track with 280wheel and its the best thing since sliced bread.
Yup. That's me in a 340whp 180sx. (No aero on this car.)
I can honestly say it's not as fun as my NA car. (No aero on this car either.)
Maybe if it had amazing down force (ahem... Kognition ), it could be a bit more fun. I can't say much, nor could a lot of us.. Most of us do not have highly engineered aerodynamics on our cars. No doubt a high horsepower car with well engineered aerodynamics would be very fun.
I'm strictly talking about a realistic observation of the average individual owning a 240sx... Not many can afford to put a 300whp 240 together AND get some serious down force. So, its cheaper to cut down on weight. It benefits in all categories. By the time most of these people can afford to modify the car to get serious power and downforce, they probably move on to better things anyway.
Regardless, weight reduction is pretty critical. Maybe not so much for minimum weight cap regulations. Then, its critical for equal weight distribution, downforce, and power.
Ugh, I think I'm biting more than I care to chew right now. I withdraw from this. Mike knows what he's talking about anyway.
