Give your FR-S and BRZ shifter a feeling of precision not found with stock bushings! Whiteline's Positive Shift Kit for the FR-S and BRZ inserts into the factory gearbox mount and results in a greatly improved shift feel and response by reducing the compliance of the heavily voided factory mount. Installing the stiffer bushing makes the shifter feel even more connected to your transmission. The material is flexible enough to allow for normal drivetrain movement, but stiff enough to eliminate the large amounts of deflection from the stock part.
