I've never talked about something logical... Just skinning this one for fun ...
First : Koni for suspentions and eibach for springs (That's what i have on my real car, Koni+eibach (work nice together ...),)
And : Brembo for brakes OK, But Sparco only for seats and wheels, they never made any brake (You also have, AP Racing, Nissin for bikes, Beringer, OMP... )
But you're right for Tyres and oils company ^^ (i'll try to fix that later ... )
