S1 Coilover Kit

The Solo Werks S1 Coilover System offers a premium, entry-level suspension upgrade with a focus on adjustable ride height and enhanced handling. Constructed with heavy gold zinc-plated housings, these coilovers are built for superb corrosion resistance. They feature large 20mm damper shafts and new progressive elastomer bumpstops for improved performance and ride quality. This kit provides a significant lowering range: 30-60mm (1.6-2.4 inches) for sedans in the front and 22-55mm (1.0-2.2 inches) in the rear. The spring perches have a silver, double lock ring design for secure adjustment, and the system utilizes platform-specific spring rates and matched valving. Sway bar end links are also included. Applications include 2006-2011 BMW E90 Sedan, 2006-2013 BMW E92 Coupe, and 2007-2017 BMW E81/E82/E87 models, all specifically for 2WD vehicles. A minimum 5mm front wheel spacer may be required depending on wheel size and offset. Crucially, this kit does not fit M models or XI (AWD) models. What's included in the box: 2 front threaded coilover dampers with spring perches, 2 front springs, 2 rear twin-tube dampers, 2 rear adjustable spring perches, 2 rear progressive rate springs, 2 spanner wrenches, installation instructions, and a 1oz bottle of Boeshield T-9 lubricant/protectant. The kit comes with a 3-year limited warranty.
