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:

6k Front & 8k Rear Spring Rate
Linear front & S-Barrel rear springs

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.

Condor Speed Shop collaborated with Syncro Design Works to create these new Monoball Rear Trailing Arm Bushings designed for the track! While also at home on the street, these performance bushings are designed to handle the stresses of the track, offering a full range of articulation for optimal suspension geometry and a sealed design for maintenance-free operation and a long life. SDW's' own 410hp shop track/streetcar still has the original prototype bearing installed in 2009, with no measurable toe deflection. Condor RTAMBs are precision CNC machined and hard coat anodized to protect against corrosion, moisture, and salt spray. They come fully assembled and ready to install. NOTE: Professional installation recommended. These bushings must be pressed into the factory Rear Trailing Arms.

Condor's Offset Rear Trailing Arm Bushings (RTABs) are perfect for the street and the track. They're designed to help correct rear toe-in and toe-out issues on lowered cars. To correct for toe-in: RTABs can be installed with the thick side inboard to help push the rear trailing arms towards the outsides of the car. To correct for toe-out when running minimal camber setup: RTABs can be installed with the thin sides inboard to help push the trailing arms inwards. The amount of total adjustment is purely dependent on how low your car is, but we've seen toe adjustment from 1/8” out on each side to 1/8” in on each side, which is a super nice range for the e36 rear end! They use UHMW in all of their suspension bushings because it is self-lubricating, meaning it requires no grease when installing, has almost zero deflection yet also absorbs some vibration. It will outlast other types of rubber or urethane bushings. They include black oxide plated steel plates for each RTAB to prevent lateral movement between the bushing material and the aluminum. Polyurethane and rubber bushings will deflect and slide, causing your rear alignment settings to change mid-corner. With these bushings, you won't have to worry about dynamic changes in your toe settings; the rear alignment stays in check during hard cornering, braking, and acceleration. This item fits the following BMWs: 1992-1998 E36 BMW 318i 318is 318ic 323is 323ic 325i 325is 325ic 328i 328is 328ic M3 1999-2005 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi M3 2003-2008 Z4 BMW Z4 2.5i Z4 3.0i Z4 3.0si Z4 M Roadster M Coupe Kit includes a pair of trailing arm bushings
