Why not just set min/max limits?
min weight allowed 3000lb
max HP 450
max torque 500 both tested on a portable chassis dyno at the event
max brake rotor size 14" max piston count 16
max wheel size 19
max tire tread width 12" rear 10" front
then you could get into the debate on shocks and sway bars..... and that could go on forever.
NHRA does it in Stock eliminator........ it has taken them 30 years to fine tune it and untill everyone starts cheating the system works.
