Powerflex Black Series Rear Subframe Front Mounting Inserts PFR5-419BLK for BMW 1 Series E81 E82 E87 E88 & 3 Series E90 E91 E92 E93 E9x xDrive 95A Polyurethane Bushes (Pair, OEM 33316758259)

Powerflex PFR5-419BLK Rear Axle Carrier Front Mount Inserts for BMW E8x and E9x

Take the slack out of the back end and get your BMW feeling planted with these competition-grade polyurethane inserts. Powerflex PFR5-419BLK uses a 95A hardness compound to rein in subframe movement, keeping rear alignment consistent under load for crisper turn in, better traction and repeatable handling on fast road, track day and race setups.

We run this upgrade on our own cars and customer builds, and the feedback is consistent every time: tighter rear end control, reduced wheel hop and a more connected drive without resorting to harsh solid mounts. If you are chasing precision and stability from your E8x or E9x chassis, this insert kit delivers.

Why choose these inserts

• 95A polyurethane insert for minimal compliance and a locked-in rear cradle feel
• Helps maintain geometry under acceleration, braking and cornering for improved stability
• Sharper response, enhanced traction and better launch consistency
• Motorsport-focused durability compared to ageing rubber mounts
• Ideal for track days, time attack, club racing and fast road builds
