Another option is to just open is up to any pre1980 car (1 model per driver to keep grid diverse) and set a time that is not allowed to be beaten for each class. Then it is up to the driver to tune/bop the car to their liking ensuring they cannot beat the set lap time.
In the race, each lap that you do beating the time could be a +5sec penalty with a max of 5 laps beating the time before being dsq
