NHRA regulations

Honestly it's going to be a street car. But may see the track once a month. I'm not sure on the classes... As that was confusing as well lol

Keep it simple. Slower than 11.49 if it's not a vert all you need is a helmet and if you run a slick you need a drive shaft loop.
Keep any fuel lines and fuel regulators off the firewall.
If it's auto make sure the neutral safety switch works.
Rear fuel cell requires a firewall.
Rear mounted battery needs a kill switch.

Faster gets more costly.
