Dinan Lowering Springs / Sport Coil Springs for BMW F10 5 Series 550i & 550i xDrive Saloon (2011-2015) - 0.5in (13mm) Front & Rear Drop - Suspension Lowering Kit, Reduced Body Roll, Handling Upgrade

Give your BMW F10 5 Series 550i the stance and precision it deserves with this Dinan sport spring upgrade. A subtle 0.5 inch front and rear height reduction - roughly 13 mm all round - tightens up the chassis for crisper turn-in, flatter cornering and a purposeful road presence without sacrificing daily comfort. Perfect for drivers who want an OEM-plus look and a more connected drive on British B-roads and motorways.

Engineered from high tensile chrome-silicon steel, CNC wound and shot peened for longevity, these performance coils deliver consistent rates and long-term reliability. The carefully matched spring rates help curb pitch under braking and squat under acceleration, improving steering precision, traction and overall balance. Expect a more planted feel, improved tyre contact and a confident, controlled ride.

We have fitted these Dinan springs to numerous BMW F10 550i and 550i xDrive saloons at MJ Modifications in Warwickshire, and customer feedback has been outstanding. Owners love the cleaner stance, the way the car rotates with less lean in bends and the way it retains a refined ride for everyday use.
