Powerflex Rear Subframe Front Mounting Bush PFR5-1220 for BMW 1 2 3 4 Series E81 E82 E87 E88 E90 E91 E92 E93 F20 F21 F22 F23 F30 F31 F32 F33 F36 - Anti-Squat Polyurethane Upgrade - Replaces 33312283382

Rear Axle Carrier Front Mount Poly Bush Kit for BMW E8X E9X F2X F3X — Powerflex PFR5-1220

Transform the way your BMW puts power down with this Powerflex rear axle carrier front mount kit, part number PFR5-1220. By replacing the soft factory rubber at the front of the rear sub-frame with high performance polyurethane, you gain crisper chassis control, improved anti squat geometry and far more consistent handling on fast road and track without the usual wear of OE bushes. It directly replaces BMW part 33312283382.

Why enthusiasts choose this upgrade

• Anti squat geometry enhancement for stronger traction and reduced squat under hard acceleration.
• Polyurethane construction resists deflection and heat, maintaining geometry where rubber gives way.
• Sharpened rear end response, better stability mid corner and cleaner power delivery out of bends.
• Durable components designed to outlast standard rubber bushes, with corrosion resistant hardware.
• OEM style fit with performance gains that suit daily driving, spirited B road use and track days.

We have installed this kit on a wide range of customer cars and our own vehicles. Feedback is consistently positive: firmer, more planted rear axle feel, less wheel hop and a noticeable increase in confidence without harshness.

How PFR5-1220 works

This kit fits the front mounting points of the rear sub-frame and raises the front of the carrier slightly to add anti squat, a geometry change similar in concept to certain M model setups. If you prefer to retain the factory sub-frame height, choose Powerflex PFR5-420 instead. Building a more track focused car and want a stiffer compound? Consider the Powerflex Black Series version of this mount.
