Sometime Later. 


This will be coming soon as I'm prepping three cars from the '79 season.
BMW 320i
Lancia Beta Montecarlo
Ford Capri III


Performance components are identical but end up in different place on each car.


Power, gearing, wings, weight, and brakes are the same.


Wheelbase, track, cog, fuel tank, and wing placement is different.
Tyres are a different size, affects gearing slightly, but not their actually performance.
Suspension styles and spring rates differ on all three cars. (damping is tuneable)
Sounds are different.( Placebo effects will be strong ) 

Hadn't thought of that, but I think we'll still be good to go.
