So i have currently the problem just how difficult driving my Automation-Group-B-Thing is or more precisely how hard it is to keep it on the road/track/course. And for some reason I can’t figure out why it is so extremely difficult https://www.beamng.com/resources/1985-malpensa-rei-bb-group-b.8489/ I got relatively good at making road/track cars but with rallying i need a bit of help. Or were the Group B cars so hard to drive?
Rally cars are really hard to get right. I managed to do it a couple of times but most of my attempts fail. You can make the best car in the world and it just won't perform well on gravel. Tyres are the main problem. I had to manually change grip levels because default automation tyres just arent good enough. Some tips for your car: try a model with shorter wheelbase, because this one is very hard to turn. Suspension is soft in front so it dips when you brake hard.
I use almost the same setup as track cars. Just increase ride height and slightly softer suspension. This is for a 105hp 560kg car so you might not get the same results.
