Bilstein B6 Sport Front Shock Absorber/Strut (Each) for BMW 4 Series Convertible F33 & M4 Convertible F83 | Non-EDC Passive Suspension | Monotube Gas Damper | OE-Height Fast Road Upgrade | Direct Fit, Standard Chassis/Stock Springs

Uprated front strut for BMW F33 4 Series Cabriolet and F83 M4 Cabriolet. This B6 performance shock is a direct-fit front unit that works perfectly with the original springs and stock ride height, delivering sharper handling, tighter body control and confident road manners without sacrificing everyday comfort.

Key benefits

• Noticeably firmer control with reduced pitch and roll for a planted, composed feel on British B-roads and motorway driving.
• Improved steering accuracy and front-end response for fast-road confidence and predictable turn-in.
• Monotube gas-pressure design for consistent damping and excellent fade resistance when driven hard.
• BMW-specific valving tuned for the F33 and F83 platforms to balance comfort and performance.
• Ideal as an uprated replacement for tired OE shocks or as the foundation for a sportier suspension refresh.

Compatibility

• BMW 4 Series Convertible F33 and BMW M4 Convertible F83 with passive suspension only non adaptive damping, no EDC.
• Front axle fitment.
• Supplied individually each unit. We recommend replacing in axle pairs for best results.
• Designed to be used with factory springs to retain standard chassis height.

What you will notice on the road

• Flatter cornering and better mid-corner stability.
• Enhanced grip and composure over rough or uneven tarmac.
• More precise steering feel with OEM-level ride comfort for daily use.

We have run these on our own cars and customer builds, and feedback has been consistently positive for ride quality, control and everyday usability. If you want a fast-road orientated upgrade that still feels refined on the commute, this is the go-to choice.
