The Dinan D100-0921 Performance Spring Set is designed for 2014-2020 BMW 435i/440i Coupe and Gran Coupe applications using the F32/F36 chassis.

Dinan lists approximately 1 inch of lowering front and rear on the F32 Coupe and approximately 3/4 inch front and rear on the F36 Gran Coupe. The springs are compatible with conventional and factory electronic shocks and increase spring stiffness while reducing body roll.

Dinan recommends pairing the spring set with the corresponding Ride Quality and Handling Kit for the intended ride height and ride-quality characteristics. The kit is not compatible with xDrive models or 435i/440i convertibles.
