This KW Street Comfort set is the refined road suspension upgrade for BMW 3 Series owners who want supple comfort, confident handling and a tasteful drop for daily use. It smooths out rough British roads, reduces float and roll, and keeps your saloon, coupe, touring or cabriolet composed on B-roads and motorways without the harshness of track-focused kits.

How it feels on the road

Shortened damper housings and carefully matched spring rates deliver a supple, composed ride with better stability and steering precision. Add rebound for extra control when pressing on or when running bigger wheels and tyres, back it off for maximum compliance over broken tarmac. The change targets rebound only, so the car remains predictable and confidence inspiring.

Built to go the distance

KW's inox-line stainless construction shrugs off winter salt and grime, keeping the threads free to adjust long term. Premium seals, valves and bushings give consistent performance and long service life, making this an ideal everyday upgrade for comfort-focused road cars.

Workshop feedback

We have fitted and used these kits on E46 platforms and they deliver exactly what road drivers want: smoother ride quality, better control and a smart, usable stance. Customers consistently report a major improvement in daily comfort without losing confidence in corners.

Fitting and alignment

Professional installation is recommended, followed by a four-wheel alignment. Corner-weighting is a worthwhile extra if you want the sharpest balance.
