What is it about the 370z that makes doing well in BS on a national level seem so impossible?

It would likely get beaten in FS as well. FS isn't four grades slower than BS, it's just another class. The more the HP friendly the course, the poorer the 370Z would do against the cars in FS, imo of course. Does anyone know if FS and BS ran on the same days and run groups at Nationals?

The limiting factors compared with a C5 Corvette are:

• 200lb heavier or more than C5
• Viscous LSD which doesn't allow the car to accelerate out of corners unless the steering wheel is nearly straight
• Very limited, non-adjustable front camber. (around 1 degree)
• Power/Torque band is great in the 50-63 MPH range (close to redline), but not great digging out of slow corners. This makes it more course dependent.

I ran BS and won our local BS class in 2016 (10 events) ahead of Brian Johns who is a national champion in ES and 3rd and 4th in BS the past two years. Also won Dixie Champ Tour in the 370. But our local courses were better suited for the 370z (more transitiony) and slick sealed asphalt. Beating one good driver is easier than beating 15. ONE of them isn't going to make a mistake while being in a better car. So even if you were perfect, you'll still be slightly off pace.

If your goal is to trophy at nationals or champ tours, you can definitely do that in a 370Z. If your goal is to win or be top 5, it's just not going to happen.
