The rear ride height would be set as low as possible, as this would raise the rear moment center and lower the CG to reduce the rear roll angle versus the front roll angle to help balance the setup.

Not because the chassis is anything magic, although it is a good chassis, but because of the knowledge that goes with it.". If it's kept stock, the conventional wisdom says that there will be fewer tuning options and that essentially translates into fewer choices for the racer to make.
