after thinking a lot, the problem with SLRR physics is probably in body motion, it doesn't seem to have moment of inertia. for example, a car of 3000kg in slrr will have the same response as a car of 850kg in slrr, its like the weight doesnt make the car harder to move. it seems like its not there because Slrr doesnt have unsprung weight, because adding removing rims/tires dont add even 1kg to the car, it might just have not been done by the devs for some reason or theyre lazy. maybe you can find a way to do this... even if its beyond your capacities lol
