Toyota Starlet GT Turbo EP82/Glanza V EP91 (1990 - 1999) Rear Gearbox Mount Bush (M-Sport) 64mm - PFF76-421BLK PFF76-421BLK uses our Black 95A durometer material for heavily tuned vehicles or Motorsport use. An 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. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
