Street-friendly comfort coilover suspension for BMW 3 Series E93 Cabriolet 2007 onwards

Transform your E93 3 Series Convertible with a coilover kit that rides beautifully on UK roads while sharpening handling. This stainless Inox-Line suspension package gives you adjustable ride height and 16-stage rebound control, so you can fine tune compliance and body control for commuting, fast road use and weekend drives. We run this setup on our own builds and our customers consistently praise the smooth, composed ride and confident steering feel.

Road-ready performance without the harshness

If your factory dampers feel tired or a previous lowering kit is too firm, this comfort-focused coilover solution delivers supple ride quality with tighter control of roll and pitch. Expect calmer body movements, better stability at speed and a more composed drive on A and B roads, city streets and the motorway.

Built to last in the UK climate

With stainless Inox-Line construction and corrosion-resistant hardware, this coilover suspension shrugs off winter salt and wet weather. The trapezoid thread stays usable, so you can tweak ride height season after season.
