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 PFF5-401G to your vehicle before ordering. If your vehicle uses a size-specific bush, measure the original component or anti-roll bar where applicable.
Product Overview＋
PFF5-401G Front Radius to Chassis Bush Caster Adjustable to provide up to +/- 0.75 degrees of on-car caster adjustment, resulting in greater in-corner camber gain, improved stability at high-speed and the ultimate optimisation of your vehicle's front wheel geometry. Made in our stiffest Black 95A material and supplied with steel outer shells for better load distribution and an offset adjustable CNC-machined stainless-steel sleeve and spanner, it combines all of the necessary ingredients to be perfectly suited to both road and track use. Over the years we have seen a shift in the use of cars such as the BMW E92 M3 and E82 1M Coupe, with more of their time being spent on track and the power, chassis and braking modifications carried out, taking them from being quick road cars to very able and incredibly fast road-legal racers. Made in our stiffest Black 95A material and supplied with steel outer shells for better load distribution and an offset adjustable CNC-machined stainless-steel sleeve and spanner, it combines all of the necessary ingredients to be perfectly suited to both road and track use. PFF5-401G Front Radius to Chassis Bush Caster Adjustable to provide up to +/- 0.75 degrees of on-car caster adjustment, resulting in greater in-corner camber gain, improved stability at high-speed and the ultimate optimisation of your vehicle's front wheel geometry. This change in design increases stiffness by a further 25% over our previous offering for improved durability and braking stability and a 140% increase over the worn rubber bush.

Frequently Asked Questions＋
Q: Will this fit my BMW 1 Series E81 E82 E87 E88?
A: This listing is specified for BMW 1 Series E81 E82 E87 E88 04-13. Always confirm the chassis, variant, component size where relevant, and Powerflex part number PFF5-401G 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 PFF5-401G. DC Prestige can also help check fitment before ordering.
