PFF5-131G is a straightforward way to change the virtual roll centre of the car to increase resistance to body roll and correct suspension geometry on lowered vehicles. Lowering the car will change the angle of the front wishbone causing suspension compression even before the suspension moves. Our roll centre adjuster kit will restore the original roll centre on these cars and includes a 5mm spacer for fine-tuning and to cater for different lowered amounts (N.B. The spacer is only suitable for 17-inch wheels and larger). Our kit includes longer High Tensile bolts to accommodate the additional thickness of the ball joint assembly. *Ball joint NOT included*. Spacer included for additional adjustment to cater for especially lowered vehicles and 17″ and above wheel sizes.
