Clear BMW chassis

Please ensure your correct model is selected

Coilovers provide more adjustability than a strut and spring setup and can serve a variety of different needs - it's important to be sure of what your suspension goals are. We have broken down our coilover catalog into street and track categories, this is not to say you can't use one of our aEURoestreetaEUR coilovers on the track, or vice versa, but it is to give you a starting point. Are you someone who is interested in getting your BMW lower than factory height for the aesthetic value and handling benefits in a daily driver? Check out our street category. The majority of these are priced to avoid breaking the bank, but providing a good value in terms of features and benefits. On the other hand, if you are putting together your vehicle with the track as its main purpose, take a look at our track coilovers category. We have hand selected these coilover brands as being more expensive coilovers built to hold up to abuse.

The H&R Street Performance Coil Over kit takes the traditional shock/spring package one step further. H&R combines their progressive-rate springs with specially valved shocks and adds height adjusters that let you set the ride height to your own personal tastes. These coil overs are designed for street use with progressive rate springs that start out soft and stiffen as they are compressed. This helps to keep the ride compliant while still giving better handling and balance.

H&R designs each suspension to work as a coil over. This means that the correct amount of travel has been built into each shock. And the shocks are valved specifically for the spring rates to give a tight and controlled ride without being harsh or ultra-stiff. Each H&R coil over is TUV tested and approved and meets ISO quality standards. These are used with the stock strut and shock mounts for a quick and easy install.

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
  • Valved specifically to spring style and rate
  • Camber Plate Front Mounts
  • Aluminum and Rubber Rear Mounts

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 -

  • Separate adjustments for compression (14 positions) and rebound (infinite settings),
  • Stiffer springs over stock for less bodyroll than the standard suspension,
  • Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,
  • Individually height-adjustable - Front = 10-40mm lowering; Rear = 5-35mm lowering,
  • TUV approved lowering range and operation,
  • Expert engineering and design for ease-of-use and long durability,

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.

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.
