Mitsubishi Lancer Evolution VII, VIII & IX inc 260 (2001 - 2007) Front Lower Rear Diff Mount (Track) 60mm Diameter - PFF44-107 PFF44-107 is made in our Purple 80A material and is recommended for track use. Please verify the size before ordering. PFF44-107 has a diameter of 60mm, whereas PFF44-108 measures 70.5mm. A slight increase in NVH, typically noticeable at idle, should be anticipated when stiffening the connecting mount between the engine/transmission 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!
