I believe (the FF guys can correct me if I’m wrong) that dropping pressures in the rear should help with your understeer. When I ran my wife’s Prizm in one event when the Fiero was dead I think I settled on 42F/25R to get some good rotation out of her 1.6liters of 3 speed auto fury.

I’ve said this before…

Nah all that does is reduce the contact patch, be brave, less tire pressure in the rear = lower cornering stiffness in the rear:

Cfa - Crb > 0 = oversteer
Cfa - Crb = 0 = nuetral steer
Cfa - Crb < 0 = understeer

For FWD car a is small…

For example a FWD car with 63/37 weight dist a would = 37 and b = 63. Therefore to approach neutral steer the cornering stiffness of the rear should be lower (achieved by running a lower tire pressure).

It’s just that overpressurizing the rear is prefered as it is much easier to control.

And just because something works on paper doesn’t mean that is what everyone is going to do it.
