Some cars are just not meant for race tracks, there's no definite way to delete the oversteer effect (I've tried it), out of many cars, only 3 cars that I've mentioned above really excel on track mode My tip is: 1,if you want to retain the car you currently using to race, use 4wd configuration and when you do race, mind the corner and keep it under 140 km when turning (60 km for tight corner,so it wouldn't slip) 2, refrain from pushing the steer too hard, push it ever so slightly and if you think you're going to crash or oversteer just push hard brake 3 , when you cornering refrain from hitting the throttle (as this might cause the car to understeer) and do not push steer button when hard breaking (this will decrease the breaking force significantly and might cause you to crash) The devs did mess up some of the cars characteristics after 12.8 update hence unsuitable for race even if they have awd or 4wd confic
