Dinan Performance Spring Set for BMW 435i / 440i xDrive 2014-2020

Special Note: Not compatible with RWD models or the 435i/440i convertible.

The Dinan Performance Spring Set for the F32 435i/440i (xDrive) offers a perfect balance of enhanced handling, improved grip, and a more aggressive stance. Here's a detailed breakdown of its features and benefits:

Key Features:

• Lowered Ride Height:

  • Front: Lowered by 3/4".
  • Rear: Lowered by 1". This provides a more aggressive stance, improves suspension geometry, and enhances the vehicle's overall appearance.

• Increased Spring Stiffness: The Dinan springs feature a 38% increase in spring stiffness in the front and a 50% increase in the rear. This increased stiffness reduces suspension compression under acceleration and braking, providing a more controlled and responsive driving experience.

• Reduced Body Roll: A significant reduction in body roll allows the car to respond more precisely to steering inputs, improving cornering stability and making the vehicle feel more agile at all speeds.

• Enhanced Grip and Handling: The stiffer springs lead to a noticeable improvement in grip, especially in high-speed driving situations. This gives the driver more confidence in the car's abilities, with better control during aggressive maneuvers.

• Durable Construction: The springs are CNC wound from high-tensile chrome silicon wire and shot-peened to relieve stress. This ensures long-term durability, preventing sagging and maintaining consistent performance throughout the life of the vehicle.

• Compatibility: The Performance Spring Set is compatible with both conventional and factory electronic shocks, making it a versatile choice for owners of the F32 435i/440i (xDrive).

Important Note:

For optimal results, Dinan recommends purchasing and installing the corresponding Ride Quality and Handling Kit alongside the Performance Spring Set. While it is not mandatory, doing so ensures the advertised ride height, performance, and ride quality are achieved. Installing the spring set without the matching kit may result in suboptimal ride quality and handling, and any claims related to improper handling or ride quality due to this mismatch will not be warranted.
