BMW M1 Procar and Group 4 Tuning

I need help with setting up the M1. The M1 is one of my all-time favorite racecars. I love the sound of it car in the game (and it's appearance)! When driving both the Procar and Group 4 M1, it feels almost weightless driving and plows through turns with very little response to steering (understeery). What setups are out there to help remedy some of these issues?

 

I think you misunderstand. When the limit of traction is reached, there is no setup to deal with it.

 

Have you already tried to raise your FFB multiplier in car setup ?
The default is way to low, i've raised it from 1.8 to 2.9. This is for the M1 Procar.
