H&R Sport Springs – BMW 4-Series Gran Coupe Only (F36, N20/B46/N55/B58)

OVERVIEW

H&R Sport Springs sharpen up the BMW F36 4 Series Gran Coupe by reducing the fender well gap and lowering the vehicle's center of gravity, which cuts body roll and improves handling.

The progressive spring rate design provides superb ride quality and comfort, staying compliant in normal driving and firming up as the springs compress. A lower wind resistance signature also makes the car more streamlined. If you are only going to improve one part of your suspension, Sport Springs are the upgrade to make.

Additional Parts Required

• None. H&R specifies no additional hardware for this spring kit.
• Four-wheel alignment after installation — H&R states that alignment must be checked after any suspension ride height modification.
• Professional installation — H&R states that its springs and suspensions should be installed by professional suspension mechanics only.
• A spring compressor and standard strut service tools, supplied by the installer, are required to disassemble the factory struts on this spring-only kit.
• Optional: Speed Logic recommends fitting Bilstein sport shocks alongside these lowering springs. Contact us for the correct F36 application.
• Confirm whether your car has standard suspension, sport suspension or Adaptive M Suspension before ordering — lowering figures differ, and adaptive damper cars must be verified for fitment.
