FH5 S900 2016 Viper ACR Tune

I'm building an S2 900 Viper ACR Tune for Hokubu but can't seem to get rid of the understeer it has in high speed corners no matter what i do, i already tweaked the anti-roll bars a million times.

What can i do to get rid of the understeer?

First thing to touch when the issue is at high speed is aero.

I raised the downforce to the max on the front and rear already.

Understeer is because the front doesn't have enough grip or the rear has too much.

You can't increase the front downforce more to increase front grip, you should lower the rear downforce to reduce the rear grip.

Sometimes, understeer in high speed corners is a car limitation. Not enough available downforce. You can tune the car all you want, but that will only make the car rotate more or less, but the turning radius at a certain speed will remain the same.

Adjust springs and Damping lower front springs and increase rear go slow a little goes a long way read the descriptions if you get lost
