BMW Suspension Parts for BMW 3 Series F30 (2012+)

Improve your BMW's handling and performance with these carefully engineered performance springs. Designed by Dinan, a premier tuning company with over 35 years of experience in BMW modification, these springs offer increased spring rates to reduce body roll and enhance control. The slight lowering effect lowers the vehicle's center of gravity without compromising daily driving comfort. The springs also reduce dive during braking and squat during acceleration, providing a more controlled driving experience.

• Reduced body roll for improved handling
• Decreased dive under braking
• Enhanced grip for better control
• Moderate lowering of 3/4" for a sporty look
• Preset to prevent spring sag and maintain performance
• Shot-peened for stress relief, ensuring durability
• Earns 2 points toward your Dinan badge
• Backed by a four-year, 50,000-mile warranty

Upgrade your BMW with Dinan's performance springs, a total package approach that preserves the original driving feel while delivering balanced and enhanced performance.

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: -1.0" (25mm)
  
• R: -1.0" (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.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The springs are worth 2 points towards your Dinan badge (Ride Quality Kit is worth 1 point).

Upgrade your BMW's suspension system with K-MAC's innovative Camber/Caster Plates and Bushing Kits.

Combat increased tire wear and frequent replacements caused by limited adjustability with these patented solutions. For over forty years, K-MAC has been pioneering fully-adjustable suspension components, allowing for precise camber adjustments and toe angle corrections, resulting in a true "full four-wheel alignment."

• Patented camber/caster plates and bushing kits for precise alignment
• Allows easy adjustment for a full four-wheel alignment
• Bolt-on installation with insertion/extraction tube included
• Easily adjusted on the car with basic hand tools
• Unique failsafe locking hardware ensures settings remain secure
• High-quality elastomer compound resists binding for longevity
• Hardened & nickel-chrome plated centers for maximum bushing life
• Spiral grease grooves for improved lubrication

For someone looking for superior performance and longevity these sealed monoball bushings are the best upper thrust bearing you can buy for an F22 2-series or F3X 3/4-series. The advantage of a monoball bearing is that it will not deflect under load. All of the rubber bushings move in all sorts of directions and that changes your alignment, especially when used with big brake kits or when driven hard. The condition worsens as the bushing wears out. The Dinan monoball sits in a CNC machined aluminum housing which has zero deflection. The monoball allows complete freedom of movement but only at the desired angles. What you get is superior steering precision, better handling from more consistent alignment, and almost infinite bushing life. And thanks to the inner liner and sealed rubber boots there's none of the extra noise or reduced service life of fully solid race bushings. 

We strongly advise using these with new control arms. BMW recommends that the bushings be replaced only once per set of control arms. So if your thrust arm bushings have been replaced already then we do not recommend re-using the arms. The other reason is that the aluminum arms stretch over time which will make the bushings loose inside the arm. Other manufacturers recommend filling the stretched arms with paste but replacing the control arm is the better solution.

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 F22 and F30-F36 chassis to reduce bodyroll, improve steering and turn-in response, and reduce understeer. Both front and rear bars are hollow tubular steel for light weight with adjustable ends to dial in the handling characteristics. 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.
