Theorie:
-mid corner handling is affected most by the anti-roll bar to solve most mid-corner steering issues.
-typically, going stiffer on the front bar will increase the likelihood to understeer. And that would be the case in a FWD, RWD, or AWD car.
-a stiffer bar on the front – in relation to the rear(softer) – will lead to more understeer.
-a stiffer bar on the rear will lead towards more oversteer.
-if both bars are made stiffer, the load transferred will remain the same, but overall chassis roll will be reduced, which may require a camber adjustment
-a possible snap oversteer may result if the rear ARB is too stiff.
If the car has too much oversteer through a corner, you can either stiffen the front ARB or soften the rear ARB to dial out the oversteer characteristic. If the car tends to understeer through a corner, you would either soften the front ARB or stiffen the rear ARB – or a combination of both.
As a rough rule of thumb, front-wheel drive cars will benefit from a stiffer rear ARB (to reduce understeer), while rear-wheel drive cars generally benefit from a stiffer front ARB (to reduce oversteer).
