Gr1 downforce maxed.. Spins out at high speed?

[wheelhp]

Im guessing there needs to be a few updates to the physics or tyre model. I like the realism of the front downforce being too high to control but I dont know too much about the oldschool gr1 cars.. but shouldnt this much front downforce just work as its the entire point of the car? Im trying to race maxed out downforce on the porsche

Its just too shaky at that one bend at spa before the final hairpin.
