KW BMW F31 F34 F36 Street Comfort Coilover kit - Inc. Deactivation For Electronic Damper (Inc. 340ix, 335ix, 440ix & 435ix)

BMW F31, F34 GT, F36 Gran Coupe xDrive comfort suspension upgrade with adaptive damper delete

Want a smoother, more refined ride without giving up a tasteful drop and precision handling on your F3x BMW? This premium height-adjustable suspension set is engineered for daily driving on British roads, giving your 3 Series Touring, 3 Series Gran Turismo and 4 Series Gran Coupe xDrive models a supple, controlled ride with confidence at speed. Enjoy a quality lowering range of around 10 to 40 mm, precise rebound tuning and long-term reliability thanks to stainless steel construction.

We have installed this package on multiple customer cars at MJ Modifications and the feedback has been outstanding: less crashiness than lowering springs, composed body control on the motorway, better stability on B-roads and a ride quality that actually suits real-world use. If your factory setup or older aftermarket kit feels too firm, this is the comfort-focused solution you have been searching for.

Why enthusiasts choose this comfort-focused kit

• Ride height adjustability approx. 10 to 40 mm for the perfect stance and practicality
• 16-point rebound adjustment to fine tune body control and plushness
• Stainless steel inox-line damper bodies for corrosion resistance in UK weather
• Durable trapezoidal threads and composite spring seats for easy height changes
• Adaptive damper control delete included to prevent dash warnings on EDC-equipped cars
• High quality components and development focused on long-distance comfort

Optimised for everyday usability

Dial in your preferred feel with the top-mounted rebound adjusters. Add a few clicks for sharper response and reduced body movement when running larger wheels, or soften it off for maximum comfort on rough surfaces and speed humps. This is the ideal daily-driver suspension upgrade for those who want premium ride quality and discreet lowering without compromising stability.
