The Powerflex replaces the original rubber bush for increased engine stability under acceleration and boosts the torque reaction of the mount for improved acceleration response. The Purple 80A material makes for a more spirited drive better suited to fast road/track use. A slight increase in NVH should be expected but improved control of wheel spin/hop is achieved. 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. Whilst an increase in material stiffness will reduce engine movement, additional noise and vibration maybe felt.Yellow Shore A 70is an upgraded replacement for the original bush, recommended for fast road use Purple Shore A 80is a stiffer material to suit higher powered cars that may be used on the trackBlack Shore A 95is our Black Series part for extreme Track and Motorsport applications for ultimate engine stabilityGraph showing Load vs Displacement of each of our materials compared with the original, rubber bush OEM Part Number: 21950-S000 OEM Part Number: 21950A-5000
