PFF26-122-12BLK Lower Torque Mount – Motorsport uses our Black 95A material for all bush components to maximise mount stiffness, resulting in a mega 1300% increase over the stock mount for uncompromising powertrain control for serious track and motorsports use. With its unique dual-sleeve fastening setup for reduced twist of the mount, this really is the N-ext level upgrade for those looking for ultimate engine stability. 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. To suit the variable requirements of the i30N driver, our new part is available in three different ratings of shore hardness to balance performance requirements. Yellow Shore A 70 is an upgraded replacement for the original bush, recommended for fast road use. Purple Shore A 80 is a stiffer material to suit higher-powered cars that may be used on the track. Black Shore A 95 is our Black Series part for extreme Track and Motorsport applications for ultimate engine stability.Whilst an increase in material stiffness will reduce engine movement, additional noise and vibration may be felt.
