The PERRIN Transmission Support reduces drivetrain movements under hard acceleration, deceleration and cornering, which allows your engine to transmit more power to the wheels. This means better, more accurate launches for drag racing and auto cross type events where you do not want drivetrain slop.
PERRIN transmission supports are made from CNC 6061-T6 aluminum which means nothing will wear out. Also, with no urethane, the support will not squeak as urethane eventually tends to do. The factory "T" shaped interlocking support does not fit snugly into the transmission support. The gaps around this "T" shaped piece allow the transmission to move roughly 0.5" in all directions. The PERRIN Transmission Support is a larger version of the factory piece, eliminating the gaps and reducing transmission movements. The PERRIN Transmission Support, will only allow 0.1" of maximum deflection keeping the back end of the tranny in place during extreme driving and giving the driver a positive shift feel.
The PERRIN transmission support will stiffen your stock transmission support which will add some NVH (noise, vibration, harshness). For most people this is pleasing, feeling a solid connection between the transmission and chassis, versus having that sloppy disconnected feel.
