Every car is a little different.
Raising the rear of the car puts more weight on the nose... It also will make the car understeer through braking zone and understeer coming off the pedal.... To much nose weight
It will also make it loose from center out.
More rear bar will make your car snappy / loose and kill power down. The 370 with its shorter wheel base than the 350... Doesnt respond well to more rear bar.
It does respond well to front bar in a lot of good ways.
Put it this way... You wont be able to purchase an after market front bar that is too stiff.
A standard Nismo rear bar may be too much rear bar some tracks.
