Audi A1 / S1 (2010 on) A1 8X (2010 - 2018) Front Strut Top Mount Bush -10mm -10mm - PFF85-431H This part has been designed to reduce the ride height by 10mm when fitted as it allows the strut to sit higher into the body of the top mount. It is supplied with a new top cap spacer made using our 95A durometer material, meaning no more modifying of original parts. For standard ride height top mounts, please use PFF85-430H. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
