Eibach Pro Kit Performance Springs for BMW 4 Series Cabriolet F33 F83 - Part No. E10-20-031-08-22

Transform the look and feel of your BMW 4 Series drop-top with this Eibach Pro Kit spring set. Engineered for the F33 and F83 convertible chassis, this upgrade delivers a purposeful ride height reduction, sharper steering response and a cleaner arch gap while keeping everyday comfort intact. If you want a tasteful stance, confident road holding and OEM-friendly drivability, this is the fast-road spring solution that just works.

What you will notice

  • Lower ride height for a sleeker stance and improved aerodynamics
  • More precise turn-in and reduced body movement in corners
  • Progressive-rate coils that balance comfort with control on UK roads
  • Designed to pair with factory shock absorbers for a hassle-free fit
  • Perfect foundation for a sportier suspension setup and plus-size wheels
  • Eibach quality and reliability backed by a 5 year warranty

Drop amounts

  • Front: 20 mm
  • Rear: 10 mm

Note: Stated lowering is based on Standard chassis. Vehicles with factory Sport suspension may already sit lower, so final drop will be reduced accordingly.
