Powerflex PFF5-4001G Caster-Enhancing Front Lower Arm Rear Mounts for BMW M2 F87

Transform the front end of your F87 with the PFF5-4001G caster-offset front lower control arm rear mounts. This Black Series polyurethane kit replaces the tired factory rubber, tightening up the front axle so your M2 feels more accurate on turn-in, more planted under braking and more consistent through quick direction changes. Ideal for fast-road and track-day use where steering precision and alignment stability matter.

Key details

• Part number: PFF5-4001G
• Location: Front lower control arm rear mounting point
• Caster shift: Fixed 5 mm offset delivering approximately +/- 0.5 degree caster change
• Compound: Powerflex Black Series polyurethane with an 18 percent stiffness increase over OEM rubber
• Supplied as: Pair of mounts
• Diagram reference: 1

What you will notice

• Crisper steering response and a more connected feel
• Extra caster for improved camber gain on lock and front-end bite
• Reduced wander and more confidence over uneven surfaces
• More stable braking with less unwanted geometry change
• Better alignment retention and more even tyre wear

By replacing the compliant stock rubber with correctly engineered polyurethane, these mounts keep the wishbone located under load, helping the front geometry stay where you set it. The result is predictable handling, consistent feedback and durability that stands up to spirited driving.

Our experience

We have installed this kit on customer M2 F87 builds and feedback has been outstanding. Owners report sharper front-end response, greater mid-corner stability and long-term alignment consistency. It is a fit-and-forget upgrade that genuinely elevates confidence on B-roads and at track days.
