BMW 3 Series E91 Estate and E93 Cabriolet Comfort Suspension Upgrade by KW Street Comfort

Part number: 18020033

Looking to soften harsh ride quality without giving up precision and stance on your 3 Series wagon or convertible. This KW Street Comfort suspension kit delivers a supple, composed drive on UK roads with ride height adjustability and 16-stage rebound control. It is the ideal daily-driver friendly suspension upgrade for the E9x platform, offering real-world comfort, confident handling and a tasteful drop.

We install these regularly and rate them highly for long-distance refinement and B-road stability. Customer feedback has been excellent, praising smoother compliance, reduced float and body movement, and an OEM-plus feel with a smarter stance.

Top reasons to choose Street Comfort for your E91 or E93

• Comfort biased damping that keeps things composed over broken tarmac and speed humps while maintaining steering precision.
• 16-click rebound adjustment so you can fine tune firmness to suit wheels, tyres and road conditions.
• Ride height adjustment around 10 to 40 mm for a subtle, practical lowering that looks right and clears everyday obstacles.
• Stainless steel damper bodies for outstanding corrosion resistance in British weather and year-round road salt.
• Composite spring perches with a dirt-resistant trapezoidal thread that keeps height changes smooth over time.
• Vehicle specific development for the E9x chassis that balances comfort, control and longevity.
• Approval paperwork supplied as per KW documentation for peace of mind.

How it feels on the road

Set softer for city driving and rough surfaces, you get a compliant, quiet ride that takes the edge off sharp impacts. Add a few clicks of rebound for motorway journeys and quicker road work to calm pitch and roll and sharpen turn in. If you have upsized wheels and tyres, the rebound adjustable shock absorbers help you dial back harshness without losing control.
