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

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

The Dinan Performance Spring Set for the F32/F36 435i/440i (RWD) provides significant improvements in handling, ride quality, and the vehicle's stance. Here’s a breakdown of the features and benefits:

Key Features:

• Lowered Ride Height:

  • F32 (Coupe): The vehicle is lowered by 1" in the front and rear.
  • F36 (Gran Coupe): The vehicle is lowered by 3/4" in the front and rear. This lowered stance not only enhances the vehicle's aggressive look but also improves suspension geometry for better handling.

• Increased Spring Stiffness:

  • F32 (Coupe): The spring stiffness is increased by 50% in both the front and rear.
  • F36 (Gran Coupe): The spring stiffness is increased by 34% in the front and 11% in the rear. These increases in spring stiffness reduce suspension compression under acceleration (rear) and braking (front), enhancing control and reducing body movement.

• Reduced Body Roll: A significant reduction in body roll makes the vehicle feel more stable and responsive to steering input, improving cornering performance. This also enhances the car’s agility and control at all speeds.

• Improved Grip: The performance springs result in a noticeable improvement in grip, especially in high-speed driving situations. This allows for more confidence in the car’s handling during aggressive driving.

• Durable Construction: The springs are CNC wound from high tensile chrome silicon wire and shot-peened to relieve stress, ensuring long-term durability and preventing sag over time.

• Compatibility: The Dinan Performance Spring Set is compatible with both conventional and factory electronic shocks, making it a versatile option for owners of the F32/F36 435i/440i (RWD).

Important Note:

For optimal results, Dinan recommends installing the matching Ride Quality and Handling Kit alongside the Performance Spring Set. This ensures that the advertised ride height, performance, and ride quality are achieved. While not strictly required, installing only the spring set without the corresponding handling kit may result in suboptimal ride quality and handling characteristics. Any claims regarding improper handling or ride quality resulting from this mismatch will not be covered under warranty.
