BMW Suspension Parts

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.

A strut tower brace adds additional reinforcement to the front strut towers, tying them together for extra rigidity. This makes the whole structure stronger with less chassis flex. Handling and steering feel are improved with better turn-in and input with no downsides. The Dinan strut tower brace is a very high quality aluminum brace with precision machined ends that match the contours of the strut tower. Other braces simply sit on top which reduces their effectiveness. This is definitely one of the stronger strut brace designs on the market. The center bar is polished aluminum with carbon fiber inlays - an unmistakable sign of precise engineering when you open the hood.

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: -1/4" (6mm)
  
• R: -1/4" (6mm)

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.

Dinan has engineered this sway bar to work only with their Roll Control System to give the M5/M6 better balance in the corners.

Dinan sway bars are carefully engineered to match the driving dynamics of each BMW chassis. Dinan's research and development finds the ideal balance between improved handling while maintaining a comfortable ride. This set has been fine-tuned for the E90/E92 chassis to reduce bodyroll, improve steering and turn-in response, and reduce understeer. The front bar is hollow tubular steel for light weight with adjustable ends to dial in the handling characteristics. The rear bar is non-adjustable. These are the same sway bars used in Dinan's Stage 1 suspension and work best with Dinan shocks and springs or a similar sport suspension and wider rear tires.
