Premium height-adjustable suspension for BMW 4 Series F33 Cabriolet xDrive

Give your BMW 4 Series Convertible F33 all-wheel drive the stance, grip and confidence it deserves with this KW Variant 1 stainless steel coil-over suspension package. This road-focused upgrade delivers precise handling, a lower centre of gravity and a clean, even drop, all while retaining everyday comfort. The adaptive damper cancellation module is included to keep the dashboard free of warning lights when replacing factory electronically controlled dampers.

Why this upgrade stands out

  • Vehicle-specific spring rates and factory-set damping for balanced ride quality on British roads.
  • Ride height adjustability front and rear for a tailored drop, improved turn-in and reduced body roll.
  • Salt-resistant stainless housings and corrosion-proof components for long-term durability in UK weather.
  • Adaptive suspension deactivation kit supplied to maintain error-free operation after installation.
  • TUV-tested adjustment range and premium hardware for a plug-in, hassle-free fitment.

What it feels like on the road

We run these on customer cars and the feedback is consistently excellent. Expect a taut, controlled chassis with smoother responses on uneven surfaces, better traction out of corners and a planted motorway ride. It is that OEM-plus refinement with the sharper, more engaging driving dynamics enthusiasts want.
