White list:

- Any oil cooler
- Any camber plate that does not alter spring or damper stroke/position
- Any rear lower control arm
- Any tranmission cooler
- Any differential cooler
- Any intake/exhaust components
- Any tune
- Gasoline only
- 180whp maximum, on a standardized dyno.
- 17x9 wheel
- 245/40/17 spec tire of sorts
- Open brake pads

2750 Minimum Car weight, including driver
- Includes gutting, standard safety provisions
- Up to 50 lbs ballast allowed, passenger side footwell only

Not mentioned = not allowed.
Swing and a very big miss. I'm glad you're not involved in making autocross rules.

For spec twin to work, it needs to be accessible (read: easy/cheap to have a competitive car) and it needs to be fun (read: fix some of the warts of the car). That's going to look something like "go to Tire Rack, buy this kit, install it, you're good." Something like this: https://www.turnermotorsport.com/p-3...it/?pdk=AQADAQ

Spec twin probably also means dealing with the torque dip somehow - again, in a cost effective way where nobody has any real advantage by spending money on extra parts or testing. That's either specific header/tune or just specific tune. Hopefully SCCA sacks up and moves past their fear of technology they don't understand in that respect.
