Dinan Performance Spring Set for BMW M3 E90 Sedan (2008-2011)

The Dinan Performance Spring Set D100-0919 includes four springs for the 2008-2011 E90 BMW M3 sedan with the S65 V8. Dinan lowers the car about 1/2 inch front and rear for improved suspension geometry and a more aggressive stance.

The springs are CNC wound from high-tensile chrome silicon wire, shot-peened for stress relief and preset so they do not sag, and they are finished in blue, as our photos show. Higher rates reduce squat under acceleration and dive under braking, and the reduced body roll makes the steering more responsive from low speeds up. The set works with conventional or factory electronic (EDC) shocks.

Fitment is the 2008-2011 E90 M3 sedan, matching Dinan's listing and other retailers. It is not compatible with the M3 coupe or convertible; the E92 coupe uses Dinan D100-0917. Dinan says to install the springs with the matching Ride Quality and Handling Kit (sold separately) to reach the advertised ride height and ride quality, and does not warranty handling or ride complaints when it is left out.

Fitting springs requires compressing them and removing the struts and springs, so a professional install and an alignment are recommended. The linked PDF is Dinan's E9x M3 alignment sheet. Dinan quotes about 7.5 hours of labor and 2 Dinan points. Emission code 5: it does not affect emissions and is legal in all 50 states. Coverage is Dinan's limited warranty: the remainder of the vehicle's factory limited warranty (up to 4 years / 50,000 miles) or 2 years with unlimited miles, whichever is greater. It ships in one carton of about 14.6 x 14.5 x 8.9 inches at roughly 24.7 pounds. Dinan installation instructions (PDF).
