7.50 (*4.50) seconds or slower:

Spring-loaded, positive reverse lockout device and functional neutral safety switch mandatory. Transmission shield meeting SFI Spec 4.1 mandatory on any car running 10.99 (*6.99) or quicker or any car exceeding 135 mph (217.2 km/h).

See General Regulations 2.14.

You know I don't know. I'm running 10.20's on N20 and they haven't said anything about a trans shield. 10.99 on motor alone so I better find out b4 I go to a real track. My track is 550' above sea level but the DA is always over 4000'

I know I could get into the 9s but I'm not licenced or the truck isn't speced to run below 10.00
