Rear Wishbone Outer Bushings, Powerflex - F48 X1, F39 X2
Urethane bushing upgrade for wishbone to improve performance with a lifetime warranty!
Powerflex Rear Outer Wishbone Bushings are the ideal replacement for the upper OR lower bushings on the rear wishbones on your F48 X1 and F39 X2 models (FWD or AWD). Also fits MINI Cooper F55, F56, F54, F60 models. These bushings are for either the upper or lower rear wishbones (lateral arms) in the outer position where it meets the trailing arm. BMW does not sell the outer bushing separate from the arm so if you only need a bushing, these are an ideal solution.
These outer bushings should only be paired with matching inner bushings, Powerflex part #PFR5-1313.
By using a stiffer material than the original rubber, these urethane bushings allow much less variation in the suspension alignment, reducing deflection and improving handling. Not only will these provide a noticeable improvement in performance, but they're guaranteed to last a lifetime!
Powerflex has extensive experience in automotive suspension and chassis systems and has combined these skills with advanced polyurethane manufacturing techniques. Durometer is standardized per fitment and location, so you can rest assured knowing the design engineers have selected the optimal urethane hardness for this specific part.
Street (Purple): mild upgrade over a stock rubber bushing. Improved performance without a great sacrifice in ride comfort.
Street/Track (Black): Uncompromised performance for the track. Nearly solid bushing with very little deflection. Much improved performance but with a penalty in ride comfort on the street.
Note: Powerflex copper-based grease is supplied with every bushing set, and they will rarely need re-lubing due to the unique design features built into the material to hold the lubricant.
