BMW 3 Series E46 (1999 - 2006) Rear Subframe Rear Bush - PFR5-4611M3H The lower half of the bush is made using our 80ShA material to provide extra support for the rear axle, whilst the upper half remains in our 70ShA material for optimum NVH absorption. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
