Supplied as a Polyurethane bush and CNC machined bracket combination, the Purple 80A materials in PFF16-531P are better suited to those vehicles above stage 1 being used for fast road/track use. A slight increase in NVH should be expected but improved control of wheel spin/hop is achieved. For an insert only use PFF16-521.
