Yellow Speed Dynamic Pro Sport Coilovers for 2006-2011 BMW 3 Series AWD Station Wagon (E91)

Yellow Speed Racing Dynamic Pro Sport Coilovers for the 2006-2011 BMW 3 Series AWD Station Wagon (E91) are designed and developed for all motoring enthusiasts wanting excellent handling without sacrificing comfort. This suspension system features 33-way adjustable dampening settings and full length adjustment to meet every driver’s handling desires. Pillowball mounts and adjustable camber plates are included for front on most kits to increase steering response, while aluminum upper mounts with hardened rubber bushings are used on some applications for noise reduction. Rear Camber Plates are available for an additional charge on some applications. This suspension system is ideal for daily driving and occasional track use. Vehicle ride height can be adjusted from as tall as 0.5" below factory height to at least 2" or more below factory height (varies per application).

A steel lower bracket is utilized for MacPherson strut type to increase rigidity for safety (where applicable). For most MacPherson strut models, the brake line bracket is welded perfectly to the steel lower mount. A high quality forged alloy aluminum lower bracket is used for Double-A Arm strut type (where applicable). The steel/aluminum lower bracket is processed with electroplated/anodized surface treatment to prevent corrosion or rust in the harsh conditions of motorsport. The vehicle ride height can be adjusted easily with the lower bracket by winding up and down to drop and raise. With the adjustable lower bracket, it allows maximum suspension travel without affecting the shock stroke since the preload and ride height are able to be adjusted independently.

Radial Bearings Included on MacPherson Style Struts

Radial Bearings are mounted under the pillowball mount to improve handling and to reduce the noise caused by camber plates on a vehicle equipped with MacPherson Struts. Many companies will charge an upgrade fee for radial bearings, however, Yellow Speed Racing USA includes them at no additional charge on all MacPherson style suspension.

High quality components are adopted to ensure product durability and stability. Each application is fully test fit and completely road tested to guarantee all our customers perfect performance and comfort.
