Honda CR-Z (2010 - 2016) Lower Engine Mount Bush Insert - PFF25-820 Made in our 70A durometer material, it is a cost-effective and easy-to-fit insert, designed to sharpen throttle response; whilst reducing wheel hop and improving the durability and longevity of the OE mount. For those looking at pushing their supermini that little bit harder in a track/motorsport environment, our 95A durometer Black Series variant is also available. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine and chassis. The harder the material used, the greater the NVH transmitted. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
