The BC Racing ER Series coilover stands as one of BC Racing's most advanced models, designed for maximum performance and tuning capabilities. Featuring large external front and rear reservoirs, separate rebound and compression adjustments, and a twin-piston design, this coilover system enables precise adjustments without the need for extra tools. Constructed using lightweight and durable 6061-T6 Aluminum, it offers various front design options for exceptional camber adjustment. Utilizing corrosion-protected springs and a diverse range of shock types, lengths, and diameters tailored for different vehicles, this kit ensures top-notch performance, whether on the street or track.
BC Racing has established itself as a trusted name in the automotive enthusiast community, thanks to their dedication to crafting adjustable coilover kits. With over a decade of experience, BC Racing delivers coilovers that are not only highly effective but also budget-friendly.
The BR Series coilover suspension kit is BC Racing's flagship product. It boasts compatibility with all stock mounting locations and components, making it the most popular and versatile suspension system in their lineup. It features linear springs whenever possible and offers impressive flexibility with 30 levels of dampening adjustment, including simultaneous compression and rebound control. Moreover, it allows for a minimum 2-inch ride height drop. BC Racing ensures top-notch quality and performance through extensive dyno testing, which includes assessing the ideal valving and spring rates for each chassis. All BR Series kits are rigorously tested for a minimum of 6 months before they are made available to the public, ensuring superior ride quality and reliability.
Key components of the BC Racing coilover system are designed for strength and performance. The upper shock and strut mounts are crafted from lightweight yet durable 6061-T6 Aluminum. The front design offers customization with options like Caster/Camber Plates, Camber plates, and Rubber Mount Plates, allowing for up to 3 degrees of camber adjustment. The Rubber Mount Plates excel at reducing unwanted NVH (Noise, Vibration, Harshness).
Lower shock mounts come in two variations: They are either made of 6061-T6 Aluminum, similar to the upper mounts (Fork or Bolt Eye Style Mount), milled from a single piece, or constructed from high-quality STKM13C steel with robotically welded brackets. 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.

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.
Cars with EDC will require the EDC Cancellation Kit (not currently available). Cars without EDC do not need any extra materials.
Lifetime warranty!

Factory Pre-set Damping
The Variant 1 is KW's basic simple and effective coil over kit that is still packed with lots of features -
This is the ideal coil over kit for a F48 owner who wants a lower, more aggressive stance and better handling. KW has set the shock damping rates to be an excellent balance for a smooth yet taut ride, and to resist bodyroll motions for better handling. The Variant 1 differs from the Street Comfort set in that it has stiffer springs and revised shock settings. If you want a sportier ride and better handling than stock the Variant 1 is an excellent choice.

Fine-tuning your coilover damping shouldn’t mean stripping out your rear seats or interior panels. On many applications, rear shock adjusters are hidden behind carpet, trim, or seatbacks, making quick adjustments a hassle.
The ECS Rear Damping Extension Kit solves that problem with a clean and functional solution. These flexible extensions relocate the adjustment knobs to an easily accessible point above the rear shock towers, letting you dial in your suspension from inside the cabin, no disassembly required.
Installation is straightforward: simply drill a small access hole in your interior trim and route the extension cables through. The adjustment knobs can be removed to allow the line to pass through smaller openings, minimizing cutting. For proper installation, be sure to fully loosen the set screw, insert the cable, then securely tighten it using the provided Allen key.
Kit Includes:
(2) Rear damping adjuster extension cables
Installation hardware and Allen key
A smart upgrade for track cars, daily drivers, or anyone who values easy access to suspension tuning, without compromising interior fit and finish.
