Frequently Asked Questions＋
Q: Will this fit my Porsche 911 997 GT2 GT3 GT3RS?
A: This listing is specified for Porsche 911 997 GT2 GT3 GT3RS 05-13. Always confirm the chassis, variant, component size where relevant, and Powerflex part number PFR57-531 before ordering.
Q: Why choose polyurethane instead of replacing the original rubber bush?
A: Polyurethane is commonly chosen to reduce unwanted compliance and provide a durable replacement at wear-prone mounting points, while the exact change in feel depends on the bush location and vehicle.
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 PFR57-531. DC Prestige can also help check fitment before ordering.
