Nissan GT-R (2008 on) Rear Differential-to-Subframe Mounting Bush - PFR46-732BLK PFR46-732BLK Rear Differential-to-Subframe Mounting Bushes use our Black 95A durometer bush material alongside CNC-machined Aluminium and Steel components to provide a durable, semi-solid mounting location for the rear transaxle; allowing your GT-R to put its power down more directly without excessive on-off throttle deflection. Stiffness is increased by 550% radially over the voided OE rubber bush. Nissan does not sell replacement bushes for this location as the bushes are sold as part of the subframe, and with a new rear subframe costing over 1200, our new bushes make for a very cost-effective replacement solution. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
