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.

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 -
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.
