Don’t give this guy ^^^^^^^^ any more tips on how to build a quick car.

Yep you are getting it.
My quickest builds do not have race transmissions and probably have whatever transmission results in the lowest PI (I will come back to this). They do not have any cage whatsoever. They do not have race brakes unless they are used as PI filler - yes there are some cars that are at say PI 600 and brakes do not tip it over to 601. That is the only time I use race brakes now.
Some cars lowest PI transmission may have a big gap between top gear and the one before it. These cars will either not be in my roster or I may upgrade to a different transmission but unlikely to be race transmission.
