Improve drivetrain location on your Audi A3 / S3 / RS3 8P MK2 with the Black Series Rear Diff Front Mounting Bush from Powerflex. Developed for the listed application, this polyurethane component is designed to reduce excess movement at the relevant mounting point and provide a more consistent connection between the drivetrain and chassis.
IMPORTANT – CHECK FITMENT BEFORE ORDERING
Powerflex applications can vary by chassis, model year, factory option, bush location and component size. Please match the listed vehicle details and Powerflex part number PFR85-523BLK to your vehicle before ordering. If your vehicle uses a size-specific bush, measure the original component or anti-roll bar where applicable.
BLACK SERIES – PERFORMANCE USE
Powerflex Black Series products are intended for more focused performance and motorsport applications. Depending on the mounting position, increased stiffness can result in additional noise, vibration or harshness compared with standard rubber bushes.

Frequently Asked Questions＋
Q: Will this fit my Audi A3 / S3 / RS3 8P MK2?
A: This listing is specified for Audi A3 S3 RS3 8P MK2 03-13. Always confirm the chassis, variant, component size where relevant, and Powerflex part number PFR85-523BLK before ordering.
Q: Is this suitable for normal road use?
A: Black Series is the more focused Powerflex range and is primarily aimed at performance and motorsport applications. Increased stiffness can transmit more noise, vibration or harshness than standard rubber or softer road-oriented bushes.
Q: Will fitting this change noise, vibration or ride quality?
A: It can. Any reduction in bush compliance may transmit more feedback through the chassis. The effect depends on the product, its mounting position and the Powerflex range used.
Q: Is professional installation recommended?
A: Yes where the job requires pressing, cutting, lowering a subframe/drivetrain component, alignment work or specialist tools. Correct installation is important for bush life and vehicle performance.
Q: How can I confirm I am ordering the correct part?
A: Match your vehicle, chassis and any size-specific information to the listing, then verify the Powerflex reference PFR85-523BLK. DC Prestige can also help check fitment before ordering.
