Mini R56/57 Gen 2 (2006 - 2013) Upper Gearbox Mount Insert (Petrol/Tuned Diesel) - PFF5-225 PFF5-225 Upper Gearbox Mount Insert fills the voiding in the OEM gearbox mount, reducing engine and transmission movement for sharper gear changes and more precise and settled transmission response during acceleration and deceleration. PFF5-225 Upper Gearbox Mount Insert (Petrol/Tuned Diesel) is made from our Yellow 70A material, providing an excellent balance of strength and compliance for improved performance, whilst limiting NVH transmission into the cabin. Recommended for Petrol models and high-torque tuned Diesel models. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
