Upper Gearbox Mount Bush Insert
PFF26-123BLK
An easy-to-fit upgrade to limit movement within the upper gearbox mount, this Black 95A Durometer insert simply fits into the voiding within the mount and is secured in place with an included steel plate. Reduced powertrain movement will result in sharper throttle response and reduced wheel-hop, making for an even more engaging and sporty driving experience. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine/transmission and chassis. The harder the material used, the greater the NVH transmitted. Not suitable for 1.0l T-GDI engine variants.
