Powerflex Black Series Rear Differential Front Mount Bush Kit for BMW G80 M3 2020+ | Track/Drag Polyurethane Final Drive Bushing Upgrade | Anti Wheel Hop | PFR5-4024BLK | Replaces 33118090205

Rear differential front mount upgrade for BMW M3 G80 performance driving

Unlock sharper launches, stronger traction and repeatable grip with this Powerflex Black Series rear final drive front mount bush kit, part number PFR5-4024BLK. Built for fast road, track days and drag use, this performance bushing reduces drivetrain movement under load to help curb wheel hop and axle tramp during standing starts and aggressive gear changes. Expect a tighter rear end and more predictable power delivery out of corners.

What makes it stand out

• Full replacement bush kit, not an insert, for precise differential support
• Black Series 95A Shore polyurethane for maximum control and stability
• Black anodised 2011-T6 aluminium componentry, CNC machined for accuracy
• Designed to cut driveline deflection and improve launch consistency
• Ideal for launch control, drag strip runs, track sessions and spirited driving
• Durable materials that shrug off heat, oils and road grime

We have fitted this upgrade on customer G80 platforms and the feedback has been excellent, with crisper throttle response and a more planted rear axle under power. As with any motorsport-focused bush of this hardness, a firmer feel and some additional NVH may be noticeable, which is a worthwhile trade for the control it delivers.
