KW Street Comfort Coilover Kit for BMW 1 Series E81 E82 E87 (2003-201

Street Comfort Adjustable Suspension Kit - BMW 1 Series E81 E82 E87 - Part No. 18020039

Give your E8x 1 Series a refined, road-friendly suspension upgrade that still tightens up body control and steering feel. This premium height-adjustable spring and damper package is tuned for everyday use on UK roads, commuting and long motorway journeys, delivering a subtle drop with superb compliance and confidence-inspiring stability.

Why this comfort-focused upgrade stands out

• Ride height adjustment for a tasteful OEM plus stance without ruining comfort.
• 16-stage rebound adjustment to fine tune firmness and support for your wheels and tyres.
• Inox-line stainless construction for outstanding resistance to salt and grime in British weather.
• Developed and validated on road and a 7-post rig for a beautifully balanced setup.
• Engineered to keep usable travel with shorter housings, so you enjoy the drop without the crash.
• Part approval §19.3 and the proven quality enthusiasts expect from KW.

Smoother daily driving with sharper responses

If your standard dampers feel tired or a previous lowering kit rides harshly, this comfort-tuned solution restores composure and control. Dial in rebound in minutes to match bigger wheels, winter tyres or loaded motorway miles. Expect calmer body movement, cleaner turn in and stable high speed manners with a cushioned, quiet ride on broken tarmac.

Built to last in the UK

The inox-line stainless struts, high grade internals and dirt resistant trapezoid thread with composite adjuster collars keep adjustments free and easy year after year. It looks great, resists corrosion and performs consistently in real British conditions.

Lowering range

Vehicle specific, tested adjustment range of approximately 10 to 40 mm. Achieve a clean stance that complements factory geometry and comfort.
