KW Street Comfort Adjustable Suspension for BMW F31, F34, F36 xDrive - Part No. 180200AC

Give your xDrive BMW the ride quality it deserves without sacrificing handling. This KW Street Comfort setup is a premium height-adjustable damper and spring package designed for everyday usability on UK roads, with precise 16-stage rebound tuning to tailor firmness to your preference. Built in corrosion-resistant Inox-Line stainless steel for long-term reliability through winter salt and daily use.

Ideal if your factory dampers or basic lowering springs feel crashy, this comfort-led suspension delivers a measured drop of around 10 to 40 mm while keeping compliance over bumps and sharper control in corners. Our workshop has installed multiple sets and customer feedback has been consistently excellent for refinement, stability and a genuine OEM-plus look.

Why this comfort-focused suspension is a winner

• 16-stage rebound tuning: quickly soften for long motorway journeys or firm up for twisty B-roads
• Ride-height adjustability for a tasteful stance and improved balance without compromising practicality
• Inox-Line stainless steel bodies for outstanding resistance to rust and grime
• Engineered by KW for real-world roads with comfort-oriented valving and superb body control
• Perfect for AWD BMW F3x owners seeking a refined drop, confident turn-in and calm high-speed stability
