Upgrade or refresh the chassis of your BMW 3 Series / M3 E46 CSL with the Road Series Front Wishbone Rear Bush Caster Offset from Powerflex. Designed for the listed application, this polyurethane component targets unwanted movement at the relevant mounting point while retaining the fitment-specific engineering required for the vehicle.
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 PFF5-5601GM3 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.
Product Overview＋
PFF5-5601GM3 offers additional +0.5 of caster over PFF5-5601M3 and is a high performance option to PFF5-4601M3, and aimed at offering greater precision for people wanting the very best from their E46 M3. This new part, fitted to the rear of the front wishbone has a hard anodised aluminium outer shell with one of our unique low friction polyurethane centre bushes. The poly/alu combination creates a low friction rotating bush reducing the forces acting on the arm. Lower arm deflection has been decreased by reducing the compliant material within the aluminium shell. Results are less movement in the arm under cornering and braking, improving steering control and feel. For the M3 models which have a thicker wishbone. Please ensure you have the correct size bush before fitting. Testing during the development of this bush has indicated stiffness gains of 128% compared with the original rubber bush. Our Black Series part increases siffness by 28%, to give an 190% increase in stiffness over the original part

Frequently Asked Questions＋
Q: Will this fit my BMW 3 Series / M3 E46 CSL?
A: This listing is specified for BMW 3 Series E46 M3 Inc CSL 99-06. Always confirm the chassis, variant, component size where relevant, and Powerflex part number PFF5-5601GM3 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 PFF5-5601GM3. DC Prestige can also help check fitment before ordering.
