Powerflex PFF5-4650 Adjustable Engine & Motor Mount Bush Kit for BMW M3 E90 E92 E93 (E9X) 3 Series 2006-2013 S65 4.0 V8 – Polyurethane Polybush Upgrade, Performance Uprated Mounts, Fast Road & Track, Mount Inserts, Lifetime Warranty

Part number: PFF5-4650

Diagram reference: 50

Unlock sharper response and rock-solid drivetrain control on your S65 4.0 V8 with the Powerflex PFF5-4650 motor mount bush set. This tunable polyurethane solution limits powertrain twist for crisper throttle pick-up, cleaner upshifts and improved traction on corner exit. Ideal for spirited road use and serious circuit work, with the added benefit of long-term durability and a Lifetime Warranty.

At MJ Modifications we have installed these on our own builds and customer M3s, and the feedback is consistently positive. Expect a more connected feel, better launch consistency and reduced shunt under load, without making the car unpleasant to live with when set to the softer configuration.
