Audi TT Models TT / TTRS Mk3 FV/8S (2014 on) Rear Subframe Rear Mounting Bush - PFR85-828 This bush uses our Purple 80A durometer material with bonded supporting washers for strengthening and a bespoke end face design to reduce noise transmission to the cabin, whilst maintaining durability and subframe location. For Seat Leon Mk 3 models, only for 4WD variants. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
