BMW Suspension Parts for BMW 5 Series E60 (2004-2010)

Looking for coilovers that will provide reliability on street driven vehicles but are also capable of feeding your weekend track demon's desire for performance? BC Racing's BR Series coilover kit may be just the thing for you.

BR Series coilovers are the most popular and versatile option offered by BC racing, offering features such as 30-level dampening adjustment (simultaneous compression and rebound control), linear springs where possible, and a minimum of 2 inches ride height drop. To ensure performance, comfort, and quality, all BR Series kits are Dyno tested during the design stage to determine the best valving and spring rates, then installed and tested for a minimum of 6 months. This kit features mounts and brackets that are fully compatible with all stock mounting points and components.

The upper shock/strut mounts are all constructed of 6061-T6 Aluminum for strength and weight savings. BC Racing design 1 of 3 types of upper mounts for each vehicle: Caster/Camber Plates (+/- 3* camber), Camber Plates (+/- 3* camber), and Rubber Mount Plates (NVH reduction). The included mount option for this kit is shown in the kit specs and features below.

Lower shock mounts are powder coated for corrosion protection and constructed of either 6061-T6 aluminum that has been milled from a single piece (fork or bolt eye mount) or of STKM13C steel with all brackets welded robotically.

The included springs come in one of 3 styles: linear, S-barrel, and V-barrel. Linear springs are used in most applications unless limited by the OE design that does not allow the use of linear springs. All spring options are made from SAE9254 steel and have a zinc coating applied under the powder coating for increased spring corrosion protection and long term reliability.

All shock bodies used in the BR Series coilovers use a 53mm shock body (unless noted otherwise) for added strength, performance, and increased fluid capacity. All shocks are then powder coated black chrome for clean styling and corrosion protection.

Elevate the performance of your BMW with Turner Motorsport's precision-engineered performance springs. These springs utilize increased spring rates to effectively reduce body roll, enhancing handling and providing a slight lowering effect to lower the vehicle's center of gravity. The result is a balanced driving experience that doesn't compromise street usability or daily comfort. Experience reduced dive under braking, improved grip, and controlled acceleration, all while benefiting from the expertise of Dinan, America's premier tuning company with over 35 years of pioneering advancements in BMW modification.

• Earns 2 points toward your Dinan badge
• Backed by a four-year, 50,000-mile warranty

Dinan has a unique approach to fine-tuning the handling of the E60 M5, E63 M6 - to improve handling and not impact ride comfort they have engineered a way of stiffening the stock front sway bar while replacing the rear bar with a slightly larger bar. Instead of the traditional larger sway bar Dinan has come up with this way of stiffening the stock front bar. They have relocated the attachment point for the link to be further away from the end - effectively shortening the bar and making it stiffer. This has a number of advantages over a thicker aftermarket bar: lower cost, the bar does not have to be removed, no tradeoff in ride comfort. Dinan's research and development finds the ideal balance between improved handling while maintaining a comfortable ride. This set has been fine-tuned to reduce bodyroll, improve steering and turn-in response, and reduce understeer. This is the same setup as used in Dinan's Stage 1 suspension and work best with Dinan shocks and springs or a similar sport suspension and wider rear tires.

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. This setup is worth 2 point towards your Dinan badge.

The installation on the front bar requires drilling a hole on each end of the bar. The drilling and installation of the relocating bracket can be done with the sway bar still on the car. Detailed installation instructions are included.

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: -7/8" (22mm)
  
• R: -3/4" (19mm)

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.
