Zinoro M12 (2013 - 2015) Rear Subframe Front Mounting Bush (Fast Road) - PFR5-420P PFR5-420P is a full replacement bush made in our Purple 80A material and replicates the geometry of the original bush. This part has been introduced to accompany PFR5-422P Rear Subframe Rear Mounting Bush which is a full replacement bush recommended for tuned road or occasional track use where a higher torque output requires greater rear-end stability. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
