BC Racing BMW Coilovers

Coilovers provide more adjustability than a strut and spring setup and can serve a variety of different needs - it's important to be sure of what your suspension goals are. We have broken down our coilover catalog into street and track categories, this is not to say you can't use one of our aEURoestreetaEUR coilovers on the track, or vice versa, but it is to give you a starting point. Are you someone who is interested in getting your BMW lower than factory height for the aesthetic value and handling benefits in a daily driver? Check out our street category. The majority of these are priced to avoid breaking the bank, but providing a good value in terms of features and benefits. On the other hand, if you are putting together your vehicle with the track as its main purpose, take a look at our track coilovers category. We have hand selected these coilover brands as being more expensive coilovers built to hold up to abuse.

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.

Specs and Features:

  • 12k Front & 4.5k Rear Spring Rate
  • Linear front & V-Barrel rear springs
  • Valved specifically to spring style and rate
  • Aluminum and Rubber Front Mounts
  • Aluminum and Rubber Rear Mounts

The DS series from BC racing offers increased control and feedback for those looking to achieve the best driving experience possible. Digressive Valving means the shock is firmer at low speed, while transitioning to a softer and more linear feel as (shaft) speed increases. This leads to a much more planted and controlled feeling in the chassis, increased feedback through the wheel, and a slight drop in passenger comfort.

The BC Racing RM Series Coilover System uses a mono-tube inverted damper in the front and rear of vehicles that use McPherson style OEM strut suspension. On vehicles that use front struts only, BC Racing provides an inverted front strut and then provides an upright BR Series damper for the rear. Inverted dampers are useful in decreasing unsprung weight by moving the greatest mass of the strut to the top where it connects to the sprung weight of the chassis, where weight can be more easily shaved. The BC Racing RM Series Coilover System uses a much larger inverted piston shaft that can handle higher lateral loads for longer periods of time without fatigue. These higher lateral loads are only prevalent on McPherson style strut suspension, not on Double A-Arm vehicles.

BC Racing's new proprietary digressive piston design offers increased damping force at low piston velocities while maintaining a linear damper feel at higher piston velocities. One of the greatest advantages of increased low-speed damping force relates to what the driver feels, e.g., roll, pitch, dive, and quick weight transitions on technical road courses. For The Ultimate In Driver Feel - Choose BC Racing DS Series Coilovers.

The ER Series coilovers bring with them the high quality and unique features seen on the BR and RM type but have the additional benefit of external reservoirs and the ability to allow the end user to individually adjust and set compression and rebound damping rates. By separating the adjustment for damping compression and rebound the ER Series allows you to dial the vehicle in to your exact needs. When braking hard whilst approaching a corner you want the car to transfer weight to the front tires to maximize grip for the braking effort and also to allow you to trail brake into the corner without the car understeering. Ride height adjustment: Ride height is determined by the position of the coil over bottom mount. The mount can be wound up and down the damper body to give a full range of adjustment. Because ride height is determined by an adjustable bottom mount rather than spring platform you retain full damper travel regardless of the ride height run. Know your protected from the elements! The damper units are black chromed steel to give superb durability even through the darkest of European winters. The aluminium components (top mounts, locking collars etc) are anodised and the steel lower mounts go through an electrophoretic disposition process followed by powder coating. A random selection of steel components (brackets, dampers, screws etc) are put through a salt spray test once a month to check the quality of the protective processes and that anti corrosive properties are kept at the highest possible standard. Features: Highly Customizable Mono-Tube Damper Linear Twin-Piston Design Height Adjustment Independent Of Spring Compression 30-Clicks Of Compression Adjustment Via The External Reservoirs 30-Clicks Of Rebound Adjustment From The Top Of The Damper Front And Rear Camber Plates Standard On All Applicable Kits Front And Rear Pillowball Mounts Standard When Camber Plates Do Not Apply Custom Spring Rates And Swift Spring Compatible Custom Valved To Match The Drivers Requested Spring Rates Swift Spring Upgrade Available On Most Applications 1-Year Warranty Against Manufacturers Defect Fully Rebuildable NOTE: LEAD TIMES ON ALL NEW ORDERS 4-8 WEEKS

For the serious BMW enthusiast, the BC Racing DS Series for the E89 Z4 offers a "no-compromise" approach to suspension geometry and thermal stability. By utilizing high-strength SAE9254 cold-wound steel springs, this system provides a highly consistent spring rate that resists deformation over long-term use. The digressive damping architecture is specifically tuned to stabilize the Z4’s low-slung chassis, providing sharp turn-in and unmediated steering feedback. Every DS Series kit is hand-assembled and fully rebuildable, featuring bearing-mounted spring platforms to eliminate "spring binding" or popping noises during low-speed maneuvers. Key Features: Enhanced Body Control: Targeted damping profile specifically reduces the "wallow" and float associated with factory suspension. Pillowball Top Mounts: High-quality aluminum alloy mounts provide direct driver feedback and eliminate factory rubber compliance. Patented Locking Ring: Features a concave lower locking ring that prevents the system from vibrating loose even under track conditions. Customization Ready: Fully compatible with custom spring rates and Swift Spring upgrades for tailored track setups. Fully Rebuildable: All components are individual and replaceable, ensuring the long-term serviceability of the system. Specifications: Vehicle Fitment: 2009–2016 BMW Z4 (E89). Spring Rates (Default): Front: 5.5 kg/mm | Rear: 9 kg/mm. Hardware: Black chromed steel shock bodies with anodized 6061-T6 aluminum components. Damping Range: 30-Way Simultaneous (Compression/Rebound). Build Type: Hand-assembled with 1.5mm wall thickness TIG-welded brackets.
