Poly Insert Set for Rear Axle Carrier Front Mounts – BMW 4 Series F32 F33 F36 2013 to 2020 – Powerflex Road Series

Transform the way your 4 Series drives with this Powerflex Road Series insert set for the rear axle carrier front location. By filling the voids in the original rubber mounts, these precision polyurethane inserts control cradle movement for crisper turn-in, stronger traction out of bends and a more planted rear end on British roads and fast-road use.

• Enhances chassis balance without the harshness of solid mounts
• Great value improvement – no need to replace the entire OE mount
• Ideal for daily driving, spirited B-road runs and occasional track taster days

What you get

• Quantity: 2 inserts – fits the front position of the rear axle carrier
• Series: Powerflex Road Series polyurethane
• Diagram reference: 20
• OE reference it complements: 33316792509
