Hi Church, I have little knowledge on the effects of spring rates on grip bias. Do you have any insight on how that usually works?
Per another forum post by "Moto-P": Start Quote:
Now having said this, installing shorter stroke, stiffer set of suspension will easily overload the stock tires, and the result will be a car that is really difficult to rotate well, and more prone to initial under-steer, making it less entertaining to drive, and a bit more risky.
My advice is therefore, to purchase a proper set of higher grip tire if upgrading the suspension all at the same time, and to choose a spring rate that is mild and soft, so that the agility of the car is not lost due to unwilling suspension, that might be too stiff. Set your shocks very soft if it's adjustable and increase it only if you can drive it without much "push" or initial under-steer. The FRS and BRZ needs all the suspension travel and shifting of the weight to flick vectors under braking (dive), and depriving it will reduce the fun factor and increase the efforts for the driver to drive it faster.
Stiff, low, suspension and stock tire is about the worst combination you can have in the FRS. Soft compliant suspension and mild drop and healthy set of fairly grippy tires is the only way to NOT ruin a great car, if this is a mild build.
