BC Racing understands the unique vision and passion that car enthusiasts have for their vehicles. They know that for many, suspension is more critical than body kits or paint jobs. It's the key to enhancing the driving experience. While many suspension companies develop products that improve the driving experience, they often limit their offerings to select vehicles, making them unattainable for the average enthusiast. BC Racing aims to change that with the BC Racing DS Series Coilovers.
The DS Series Coilovers feature a proprietary digressive piston design, providing increased damping force at low-speed piston velocities, which is what drivers feel when taking on their favorite tracks or twisty mountain roads. This approach aligns with the long-standing standard in the racing industry, where low-speed piston velocities (0mm/s to 50mm/s) are crucial for driver feel and vehicle control.
BC Racing has harnessed the passion for driving that all automotive enthusiasts have and combined it with the best features from their BR Series Coilovers. They have engineered components to enhance the driver's experience, conducted rigorous in-house testing, and set a reasonable, affordable price for their BC Racing DS Series Coilovers. These coilovers are available for over 350 vehicles, from the Toyota Camry to the Nissan GT-R and beyond.
Adjustable Rebound & Compression Damping
Want full control? The KW V3 gives you multiple settings for both rebound and compression. You have full access over ride comfort and handling to dial in that perfect setup. Race teams rely on adjustments to get that perfect lap time and having shock controls at your fingertips is key. KW V3 features -
Whether you track the car often or only use it for backroad carving the V3 will give you the tools to set up an ideal handling condition. You can crank it up for smooth and fast surfaces or soften it for city or rough roads. Since each shock is 2-way adjustable you can alter the front-rear balance to account for brake dive or squat during power application coming out of the corner. You are in total control!
Coil over suspensions are better engineered suspension options compared to a standard shock + spring package. Since the springs and shocks in a coil over are designed by a team of engineers to work together, there is much better suspension travel and more precisely tuned specifications for spring and shock rates. Using separate shock and spring specs may result in premature coil bind or shock bottoming. And most coil over kits offer more features than the traditional packages. Coil overs are also more useful when larger wheels/tires are used because you can precisely set the ride heights to clear the new tires.
Fitment Note: Wheel spacers may be required depending on wheel/tire sizing and ride height setting.

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:
The B16 PSS9 coilovers offer a stiffer spring rate than stock and a lower ride height for less bodyroll and better handling. These are among the easiest coil over kits on the market - no special mounts required (works with stock mounts and sway bar links), larger adjustment knob allows for easy shock damping changes, and coil over spanner wrenches included for easy height changes. Bilstein backs up their technology with a limited lifetime warranty. TUV approved for fitment, safety, and quality!
Bilstein's monotube shock dampers in the PSS9 offer 9 precise settings for compression and rebound. A new setting is just a click away, allowing you to set a ride and handling combination that works for your setting. Instead of offering too many shock settings that you're never going to use, Bilstein has chosen ten optimal damping curves from a smooth street setting (P9) to an ultra-stiff track-only setup (P1). Shock changes are made from an easy-to-use over-sized adjuster knob.
Ride height adjustments are done from perches that ride on each shock body, which are zinc coated for excellent wear and corrosion resistance. You can set the ride height between 0.5 to 1.3 inches lower than stock ride height. Springs are progressively rated so their initial compression rating is quite soft and then becomes stiffer as the spring compresses. These are stiffer than most coil over kit manufacturers and the results of Bilstein's extensive testing on the German Nurgburgring and Autobahn.
The fitment of these is just like a standard shock and spring package. The front struts and rear shocks are compatible with the stock strut and shock mounts. You can re-use your own or choose a mount with additional features. Because the Bilstein design keeps the sway bar tab in the original location, you can re-use the stock sway bar links. Using the stock mounts keeps the cost and complexity down and allows for TUV certification. You can also be assured of the stock mount's quiet and long-lasting performance. The assembly of the front strut is the same as a the factory strut. In the rear, ride height is made by an adjustable spring perch that sits under the rear spring. Install instructions and diagrams included.
If you're looking for a supremely capable and high quality suspension, then look no further than the Bilstein PSS9. It combines all of the best German engineering with real-world development, and a lifetime warranty.
Fitment note: this system works only on cars not equipped with the factory EDC electronically adjustable shocks.

Bilstein has teamed up with Eibach to offer matched shock and spring packages. These Eibach springs are mated to a special set of Bilstein shocks to deliver a sporty and taut ride with as little impact on ride comfort as possible.
The Sportline kit uses an Eibach Sportline spring with Bilstein's Sport shocks and struts. Instead of taking parts from different manufacturers, Bilstein has tested the performance of the Eibach spring and tailored their shocks to be a true match for the new spring rate and ride height. This is known as a matched shock and spring and very few tuning companies take these extra steps. Eibach Sportline springs are more aggressive than Pro-Kit springs, which tend to be softer overall than most other aftermarket springs, but still ensures ride quality stays close to stock comfort while still giving you a much more aggressive lowered stance and significantly improved handling.
Bilstein B12 Features:
Most cars don't need coil overs to improve their handling and bodyroll. For most drivers, simply replacing the shocks and springs with performance versions will meet their goals. If your shocks need replacing, and you felt the handling could be improved a little bit, this is an excellent performance suspension for you.

In both cases, a powder coating is applied for enhanced corrosion protection and aesthetic appeal.
All springs used in BC Racing's coilover kits, including linear, S-barrel, and v-barrel springs, are manufactured from SAE9254 steel. These springs feature a Zinc coating beneath a powder-coated finish, ensuring resistance to rust and safeguarding performance and reliability. Linear springs are preferred in locations where the vehicle's original design permits them, while S-Barrel or V-Barrel springs are used to match OE shape/style specifications in cases where linear springs are not feasible. The spring rate is adjusted accordingly to maintain a linear response.
BC Racing crafts their kits using a diverse range of shock types, lengths, and diameters, tailored to each vehicle's requirements based on comprehensive R&D data. Each shock undergoes manual assembly at their factory and is subject to dyno testing to ensure precise quality and performance. Shocks are paired based on their compression and rebound values after dyno testing, providing even and reliable performance. The shock body used in the system boasts a 53mm diameter, delivering added strength, performance, and increased fluid capacity, unless space limitations dictate otherwise. To round it off, the shocks are treated with a black chrome finish, providing a clean, cohesive appearance and enhancing corrosion resistance.

H&R has introduced this Street Tuner CoilOver suspension kit for the 1M that has several unique features for the discerning enthusiast. H&R has designed this premium coil over specifically for the 1M using new materials and features not found on a typical 135 or M3 kit. The key features of this kit are the aluminum rear shocks with solid, Heim-joined lower mounts. The lighter weight from the aluminum and the free motion from the lower monoball makes for a more efficient shock motion and better response from the suspension. Combine these with our monoball upper shock mounts and you have race-bred shock technology for the ultimate BMW driver's car. H&R finely-tuned the rear shock dampening to reduce wheel hop. The wheel hop is inherent in the 1M and these H&R rear shocks go a long way in eliminating it. The front struts are a true nickel-plated, threaded body replacement for the stock strut. All four progressive-rate springs are included and rear aluminum ride height adjusters complete the set. You'll find this kit on H&R's own Project 1M so it has been dialed in by some of the best suspension engineers in Germany and the USA.
These 1M Coil Overs are height adjustable in the front and rear using spring perches associated with each spring. This helps to improve handling by lowering the center of gravity, reducing bodyroll with a stiffer spring, and reducing the unsightly wheel-fender gap.
Front Adjustment Range: -1.2 to -2.3 inches from stock
Rear Adjustment Range: -0.3 to -1.3 inches from stock
