Eibach Pro-Kit Sport Springs for BMW 4 Series Convertible F33 F83

Part number: E10-20-031-07-22

Give your BMW 4 Series drop-top the stance and handling it deserves. This Eibach Pro-Kit transforms the way your cabriolet turns in, grips and looks, delivering a tasteful ride height reduction with everyday comfort. Engineered to work with the factory shock absorbers, these progressive-rate coils improve road holding and reduce arch gap without the harshness associated with cheap springs.

We run these on customer cars and the results are consistently superb on real UK roads - tighter body control, crisper steering response and a sportier, level posture that complements larger wheels and performance tyres. If you want a quality suspension upgrade that feels OEM-plus rather than crashy, this is the proven choice.

What you will notice

  • Lower ride height for a cleaner, more aggressive stance
  • Flatter cornering and reduced body roll under load
  • Sharper turn-in with improved mid-corner stability
  • Reduced front end dive under braking and squat on acceleration
  • Designed to pair with standard dampers - no need for coilovers
  • Progressive spring characteristics for comfort over bumps
  • Ideal first step in a performance suspension refresh

Lowering and specifications

  • Approximate front drop: 20 mm
  • Approximate rear drop: 10 mm
  • Front axle load: 965
  • Rear axle load: 1290

Important: All figures are measured against the Standard chassis. Factory-lowered models such as M Sport generally see a smaller additional drop. Subtract the OE lowering to estimate your final ride height change.
