Improved Handling. CHECK. Incredible New Stance. CHECK.

We have all pretended at one time or another to be a fearless race car driver, hurtling into and out of sharp hairpin turns with elegance and precision. Unfortunately most of us realize the limitations of our vehicle and only half-heartedly perform the day-dream. However, you can be one step closer to realizing this fantasy with a performance minded solution. The Dinan high performance spring set and supplemental ride quality and handling kit for the F85 X5M or F86 X6M provides unprecedented handling / cornering ability in addition to lowering the vehicle into a much more aggressive stance.

Star Class Motors is proud to offer Dinan performance solutions. At Dinan their passion for both BMWs and BMW parts is evident in their dedication to designing and producing the most innovative and performance driven BMW aftermarket parts on the market. Serious enthusiasts turn to Dinan because they appreciate their ability to make BMW performance upgrades that outperform the rest of the BMW aftermarket industry.

Suspension systems that not only transform the stance of the vehicle but also maintain ride quality and improve upon handling are what Dinan suspensions are known for. This is accomplished by pairing springs sets with bump stops, spring perches or both to maintain suspension travel resulting in a smooth ride while also improving mechanical grip and handling. This is what makes Dinan suspension systems unique. While we are able to sell each component separately it is highly recommend that both the spring sets and the supplemental ride quality and handling kits are used in tandem in order to maintain the Dinan quality standards our customers are used to. Experience the Dinan difference with this combination and enjoy the ride it provides.

Dinan’s Performance Spring set for the F85 X5M and F86 X6M provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the vehicle by a 5/8” in front and 3/4” in the rear for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot peened for stress relief to last the life of the car. The 10% increase in stiffness to the springs will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also provide a noticeable improvement in grip, for high speed driving situations that will inspire confidence in your car’s capabilities. The reduced body roll makes the steering more responsive to driver input.

Benefits of the Dinan Performance Spring Set for the F85 X5 M & F86 X6 M:

  • Decreased body roll from higher spring rates (10% increase in front)
  • Lowers the vehicle 5/8” in front and 3/4” in the rear
  • Shot-peened for stress relief
  • Preset to prevent spring sag
  • Compatible with factory electronic shocks and load-leveling systems

NOTE: Dinan Performance Spring sets should be purchased and installed with the corresponding Ride Quality and Handling Kit to achieve the advertised ride height, performance, and ride quality. While not explicitly required, if the matching component is not purchased and installed you will get less than favorable results in the form of poor ride quality and improper handling traits. While we will maintain a full warranty on product defects, any claims against the car’s improper handling/ride quality traits due to not purchasing the corresponding handling kit will not be warranted.
