car set up advice needed

[Larry Herman]

Michael, as long as your suspension components (ball joints, wheel bearings, struts, shocks) are in good condition, you need not worry about any "additional loads" placed on them.  They can handle the cornering forces just fine.

Brian is right when he says that it is exaggerated by the short wheelbase, but even the 996/997 cars do it.  The problem is that the rear weight bias and relatively soft springs cause these cars to "sit down" on the rear suspension, and under hard cornering with full throttle, they will lean and squat enough to lift the inside front.  Running larger sway bars with stock springs makes this worse because typically the front bar is stiffer than the rear.

The only way to "fix it" is to run really stiff rear springs (like on the order of 1000+ lbs) with properly matched front springs.  That will prevent the car from squatting in the back and keep the front more planted, but it is not a 100% cure because I have even seen F1 cars lift their front wheels on occasion!
