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 witha 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 ourBlack Series95A material,increasing stiffness by 550%:
