hey, i don't think that visual mods are necessary... but there should be real cars along with the race car counterparts...
but hey, @thread starter... just get a tweak of some kind... and race in a server where you know the people and where EVERYONE is tuning their cars... you can get engine, transmission, and weight mods, and you can already mod the suspension and gearbox in the garage, you can totally modify a car to be like a real car...
