This component is suitable for arms with 65mm diameter silent blocks, for 75mm silent blocks see the reference PFF3-702. Here is a replacement component in the Powerflex Road series that is 100% stiffer than the original rubber bush, to support a greater load in this part of the car. PFF3-802G offers a caster setting of +/- 0.5 that can be adjusted for a better steering feel. An increase in caster increases negative camber when cornering, which increases the tire's contact patch when cornering. For a non-tunable version of this silent block, see reference PFF3-802.
