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.

The rear damping adjuster on coilovers is usually hidden under a bunch of hard to reach interior panels requiring you to remove carpet, panels and sometimes even the rear seat back in order to adjust the dampening on your BC rear coilovers. The BC Racing rear extender adjuster allow you to make these adjustments without removing the rear interior. Simple make two small holes in the interior above the adjuster and the extension can be passed through the interior panels. Now the adjustments can be performed from above.

A worn or collapsed rear shock mount introduces unwanted play into the rear suspension, leading to rear end instability, imprecise handling through turns, and annoying cabin rattles. Installing this OE-grade Rein rear shock mount stabilizes the shock absorber shaft, restoring firm damping control and preventing severe suspension impacts from transferring into the body structure.
