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.

Our sealed Monoball Rear Trailing Arm Bushings (RTAB) are the best solution for completely eliminating deflection and unwanted toe changes on the rear of the E36, E46, and Z4. While rubber and urethane bushings flex during load, the toe can change widely giving you nervous and unpredictable handling. These RTABs have a solid aluminum housing with a high-quality sealed OE bearing. These bushings were developed from years of competition use in various racing and HPDE events. There is simply no better RTAB unless your racing class rules prohibit the use of mono or spherical bearings.
The rear trailing arm bushings take a lot of abuse from acclerating, braking and cornering. The stock rubber bushings are just not up to the task of keeping rear wheel alignment in spec for very long, especially if you have upgraded to stickier tires and a better suspension. The pliable rubber flexes and twists which slows down reaction time and leaves you with a car that feels nervous and 'tail happy'. Urethane helps to control the alignment but issues with fitment, maintenance, and longevity keep us from recommending urethane on anything but a street car. We also offer a Delrin RTAB for cars that must conform to certain racing class rules. These sealed spherical bearings are the best at controlling rear toe alignment.
Our aluminum RTABs are very well made - high grade aluminum alloy and steel CNC'd out of a billet by an ISO 9001 certified manufacturer, each component is either hardcoated or nickel plated. While multiple manufacturers offer two piece designs, our research showed that a one piece bushing is a better design featuring a sealed bearing to keep contaminants out extending the life of the bearing.

TMS rear subframe bearings are designed to limit rear control arm movement relative to the subframe. The stock BMW subframe bushings are made out of rubber, which allows variance in suspension position due to deformation and compression. A race car needs to have all suspension points remain in place for proper setup. By using high grade aircraft aluminum alloy and high performance race bearings, the TMS bushing replacements are both lightweight and strong. The casing is designed so that if maximum motion occurs, the load will be evenly distributed throughout the casing. Our flanges are designed to spread the load on the subframe and limit movement. The bearing we use is an extra wide race bearing to distribute the load over a broader area. Each piece is anodized or nickel plated to withstand corrosion. These bushings are a perfect compliment to the TMS lower camber arms.

Our renowned TMS adjustable front sway bar / swaybar links for BMWs are now available in custom lengths, making them easy to order for any aftermarket or custom suspension setups. Simply measure for your ideal link length, and order the links with the best length range (below). Each sway bar link has a 10mm diameter mounting pin/stud, which is the typical factory/stock size for a universal fitment. These are sold by the pair, and each set includes two matching sway bar end links.
These end links offer the quiet operation and long life of "stock" BMW end links, but with the strength and adjustability of rod-end style sway bar links. These sway bar links can be used on a wide variety of BMWs and aftermarket BMW suspensions. When measuring, please consider that the length ranges of our Custom Adjustable end links are measured from the center to center on the end link mounting stud / pin, as shown in our diagram.
Note for E9X M3: the unique mounting on the M3 strut requires a set of our adapter seats (#TSU9912AF9). You can add them with your links from the menu below.

The rear subframe is the heart of the BMW rear suspension. Not only do all of the suspension arms attach to it, the driveline runs through it via the differential and half-shafts. Therefore, a track-prepped E46 should never see any flex or deflection in any of the subframe mounts. Excessive movement here transfers to unwanted suspension motions elsewhere and is also a major contributor to failures in the rear floor sheetmetal.

Our experience with spherical front control arm�ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).��We wanted to offer e30, e36, and e46 owners similar levels of handling precision and control for the track and street, but weren�t satisfied with the other options out there.� Instead of a Delrin bushing or unsealed spherical bearing alone, we selected an oversized sealed greaseable spherical monoball to offer unparalleled durability and precision, but designed a Delrin adapter sleeve to help isolate the added noise, vibration, and harshness that a full solid monoball bearing will have.�While race-ready,�our hybrid Delrin/monoball control arm bearings are more at home on the street than other kits that are advertised as��race-only� bearings. We did extensive street, autocross, and track testing to ensure the spherical bearing used in this bushing design excelled in each setting.
The stock rubber bushings, even�those found in the M3,�allow significant fore/aft movement of the front wheels to help absorb road impacts, especially when being pushed hard. �This soft flexible design maximizes daily driving comfort, but also allows considerable alignment change.� This unwanted deflection�stands between you and a crisp, confidence-inspiring driving experience. �The advantage of a monoball bearing is that it will not deflect under load, eliminating all unwanted deflection while still allowing�complete freedom of movement�in the desired angles. What you get is superior steering precision with better handling from more consistent alignment�and direct braking feedback, with exceptional service life.� Thanks to the�Delrin insert and double lip seals, there's none of the extra noise or reduced service life�often�found on�other�spherical bearings.
In short, if you're seeking front control arm bushings that offer precise, predictable handling, crisper braking feel, with a long service life free from noise - look no further. We have you covered.

Here at Turner we understand the importance of an upgrade that will get the results you need on the track and still be tolerable on the drive around town. When it comes to control arms on the track, making them as stiff as you can (usually using solid mounts) is the best way to increase your driving precision by eliminating the deflection of rubber. The next best thing to create a balance would be to stiffen up the control arm with polyurethane, giving you the option of a more stock like feel with 80a or closer to the solid feel with 95a durometers. These poly bushings will give your control arms a direct connection between your suspension and the body of the car eliminating the slop felt under take-off and braking so you feel more in control of your vehicle.
This item fits the following BMWs that use a centered-style bushing:

You get the best of both worlds with this pair of Turner Motorsport adjustable sway bar links. We searched far and wide to find the hidden gem of swaybar links. You get the same quiet operation and long life as the stock links plus the strength and adjustability of rod-end style sway bar links.
With the wide range of suspensions and sway bars available today adjustable sway bar links can help you with many problems. Along with the ability to remove preload you can change the length to maximize sway bar geometry. Example: if the sway bar hoop comes too close to the steering rack, oil cooler, or under tray in its suspension travel you can adjust it by simply lengthening or shorting the adjustment rod. In some cases you may need a longer or shorter adjustment rod to achieve optimal geometry. We also offer these same links in other custom lengths (click here) that may not be specific to BMW chassis.
