Vehicle: BMW M4 F82 coupe and F83 convertible

Eliminate unwanted movement in the rear drivetrain of your F82 F83 with the Powerflex PFR5-4025 front differential mount bush set. This 4 piece urethane bushing kit with precision machined alloy sleeves locks the final drive in place for sharper throttle response, predictable traction and rock solid rear axle stability on fast road and track.

Factory rubber mounts soften and deform with age and heat, leading to diff wind up, clunks and rear-end vagueness. Powerflex engineered polyurethane resists deflection under load, keeping the final drive correctly located so your tyres maintain consistent contact and your alignment stays true when you accelerate, brake and change direction.

• Controls torque reaction to reduce wheel hop and axle tramp
• Tighter rear-end feel with improved traction out of corners
• More consistent geometry under load for confidence on spirited drives
• Helps minimise uneven tyre wear by limiting unwanted movement
• Durable, corrosion resistant alloy sleeves for long term reliability
• Powerflex Lifetime Warranty for peace of mind

What you receive

• 4 x polyurethane bushings for the front mounts of the rear final drive
• Matching alloy sleeves to support and guide the assembly

Why choose this upgrade

• Ideal for fast road, track day and tuned M4 builds
• Reduces driveline slop and improves throttle-to-tyre connection
• Balances performance control with day-to-day usability

We run this kit on our own cars and customer vehicles. Feedback has been consistently positive, with owners reporting a more planted rear axle, cleaner power delivery and a notable uplift in driving precision.
