Transform the way your E46 M3 drives with this high performance polyurethane RTAB kit. These uprated rear arm bushings reduce unwanted rear axle movement, keep suspension geometry stable under load, and tighten up the back end for crisp turn in and confident braking. Expect a more planted feel on fast road and track days, better feedback through the chassis, and improved tyre wear compared with tired factory rubber.

• Far greater control of rear toe change under acceleration and braking
• More precise cornering and predictable balance at the limit
• Helps maintain consistent contact patch for improved grip
• Tough polyurethane for long service life and reduced deformation
• Designed to manage NVH while delivering sharper response
• Backed by the Powerflex lifetime warranty

Weak, perished OE bushings allow the rear control arm to shift, causing instability, tramlining and uneven tyre wear. This PFR5-3608 upgrade is a proven fix. We run these on our own builds and customer cars, and feedback is consistently positive – tighter rear end, cleaner turn in and greater confidence on B roads and circuit sessions.

Who is it for

• Enthusiasts who want a fast-road suspension upgrade without excessive harshness
• Track day drivers seeking consistent alignment and repeatable handling
• Owners replacing worn rear arm bushes and wanting a fit-and-forget solution

What is included

• 2 x polyurethane rear trailing arm bushings – PFR5-3608
