Sway Bars –
Increasing Front –Massively More understeer
Increasing Rear – Massively More oversteer.
Decreasing Front – Massively Less understeer.
Decreasing Rear – Massively Less understeer.

Okay, so this is only my 2cents. Suspension turning can be done 1 million and 1 ways. I like stiff setup, the rears always close to the front in terms of stiffness but never exceeds. I drive a FWD, my issue is understeer. Easiest way I see is introduce more oversteer into the car. This can be very scary for some people.
