The stock rear toe link setup is built with rubber bushings and a curved forged alloy rod which can easily flex. During hard acceleration and braking, this flex allows the rear wheels to have excessive toe change which ultimately causes the car to be unstable. Dinan stops the flex by replacing the rubber bushings with Teflon lined machined steel rod ends
