BMW Springs

For the driver that demands the best out of their vehicle. The Dinan Adjustable Coil-Over Suspension was bred in the race lab but refined on the street for maximum versatility. No matter the environment, the traction that is awarded to the vehicle from the improved suspension will inspire newfound confidence when running at higher speeds. From the substantial reduction in body roll as well as reduction of dive under braking and squat under acceleration, Dinan guarantees you superior handling, performance, and comfort.

Dinan's design retains the superb factory electronic shocks but swaps the springs to a more aggressive, performance enhancing formula and implements threaded collars that allow the user to change the ride height themselves. While shorter, stiffer springs are commonplace in aftermarket suspensions and are a key element in reduction of body roll it is not a one size fits all approach. In the case of the G87 M2 where the vehicle has a penchant for oversteer, stiffening the rear springs would exacerbate the problem of the rear losing traction before the front when the platform is pushed to the limit. Dinan instead has opted to soften the rear spring rate as well as switch from the factory progressive rate rear to a dual rate spring setup. The combination increases predictability and compliancy, and in turn, provides better rear grip/road holding for a vehicle that needs both. The result is a sleek lowered stance that provides improved handling to go along with its stunning visual appearance. The springs combined with progressive bump stops and other components increase travel that allow the car to be lowered up to 1-1/8" in the front and over 2" inches in the rear. However, to retain the ride quality synonymous with Dinan suspension kits the recommended drop of 3/4" in front and rear is advised. For suspension connoisseurs, or those that are just simply very particular, suspension packers are included to fine-tune handling and comfort by changing the clearance of the progressive bump-stops --- something no respectable race car is without.

Contrary to the market norm, the Dinan G87 M2 kit is not a direct carryover from the G8x M3/M4 but a package independently developed to eke the most out of the M2 and the nuances that differ it from its larger siblings. The rear spring rates in particular on the smaller coupe are far more aggressive than those on the M3/M4 from the factory. This produces a stiffer, more uncomfortable ride than most are fond of beyond the racetrack. While utilizing the same rear springs as the Dinan M3/M4 kit is possible the rates would be substantially softer resulting in reduced stability in cornering and an increase in body roll. Instead, Dinan M2 rear springs are 13% softer than factory but still 10% stiffer than what the M3/M4 kit would offer so a more compliant and comfortable ride can be achieved while also retaining its sporty character and abilities.

NOTE: Due to the extensive lowering possible and the increased suspension travel, the installer must carefully evaluate tire clearance under all situations. Safety will be compromised if all precautions are not taken. Dinan is not responsible for any property damage or injury.

Features:

• Up to 1-1/8" of lowering in front and over 2" of lowering in back are possible depending on tire clearance but with diminished ride quality
• Dinan recommends a 3/4" drop in front and rear to maintain a civilized ride
• Up to 1" of lift in front and over 2" in back over stock are also possible
• Threaded collars allow easy and precise front & rear vehicle height adjustments
• Spring rates are 29% stiffer in front and 13% softer in the rear for increased predictability and compliancy
• Substantial reduction in body roll
• Dinan-spec progressive bump stops improve ride quality at lowered ride heights
• Included suspension packers allow adjustment of bump-stop clearance to fine-tune handling and comfort
• Components are machined from 6061-T6 aluminum and black anodized for a sporty appearance as well as corrosion protection
• Stock upper spring mounts are utilized as well as spring isolators for quiet operation

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 recommended 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 F95 X5M and F96 X6M provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the car 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 increase in stiffness 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 and will be noticed at low speeds up to the top speed of the vehicle.

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 cars improper handling ride quality traits due to not purchasing the corresponding handling kit will not be warranted.

Dinan Performance Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW springs are carefully engineered to work within your car's suspension travel and to improve suspension geometry. Spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap.

Dinan spring specs -

• F: -3/4-1.0" (19-25mm)
  
• R: -3/4-1.0" (19-25mm)

Fitment note: When used with stock shocks the Dinan Ride Quality Kit is strongly recommended. The Kit consists of shorter and stiffer bump stops and spring perches that work better with the lowered ride height of these springs. While not explicitly required, less than favorable ride quality and handling may result without them.
