Powerflex Black Series Engine/Motor Mount Insert Kit for BMW M3 F80 3 Series (2014-2018) S55 – Track/Race Polyurethane Drivetrain Mount Bush/Bushing Upgrade – Wheel Hop/Engine Rock Reduction – PFF5-4021BLK

BMW M3 F80 Motor Mount Insert Upgrade - Part Number PFF5-4021BLK

Unlock sharper response and tighter drivetrain control on your F80 with this Black Series motor mount insert set. Designed to occupy the voids in the factory mounting, this race-focused upgrade curbs unwanted engine rock under load, delivering cleaner launches, faster gear changes and more consistent power delivery on track days and spirited road use.

Built from a tough Black 95 Shore A compound, these inserts sit neatly into the existing mounts to add stiffness without the need for a full replacement unit. It is a smart middle-ground between solid alloy solutions from BMW Motorsport and complete replacement race mounts, giving you serious performance gains while keeping the original mount bodies in place.

• Crisper throttle pick up and improved pedal feel
• More precise shifting and better driveline alignment
• Reduced engine movement under acceleration and braking
• More immediate power transfer to the rear wheels
• Helps extend the life of the original mounts

Track-bred performance

The Black Series compound is engineered for competition use, offering maximum control of chassis geometry for circuit and fast road driving. If you are chasing lap time consistency and stability from your S55-powered F80, this is the upgrade that keeps the front end planted and the drivetrain composed.
