Thrustmaster Ferrari 458 Problem with RWD cars

so i love using the wheel, been a lot of fun however I am having problems with RWD cars when im accelerating out of a turn the over steer is so ridiculous and i spin out. Typically happens with heavy/old cars like the Miura when i was more than able to get it around the track with a controller, i can get the P1 around the track just fine tho i do feel it at times but i can correct easily enough, but with the bigger/older cars it just takes the car into a death spin. Any suggestions, maybe a setting or how to approach turns with the wheel in a way i havent been used to with a controller? Thanks!
