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 ... )
Would it be possible to be able to set the shinig level of some parts of the car or some areas. I mean, Stickers on our skins are not very realistic because of the shining level that is the same as the car... Or, another exemple, For carbon look on wings or roof, same problem, too shiny !!!
I don't know exactly how the background works and I'm sur that it's something very hard to do but if it works one day, I think that Lfs will have the greatest skins ever
