Powerflex Rear Differential-to-Subframe Mounting Bush Nissan GT-R 08+PFR46-732 Rear Differential-to-Subframe Mounting Bushes use our Purple 80A 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 250% 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. For those after a track/motorsport-focused, no-compromise solution; these bushes are also available in our Black Series 95A material, increasing stiffness by 550%:
