BMW 4 Series and M4 Coilovers

We carry eighty BMW 4 Series and M4 coilover kits. Most of the choice comes down to three things: 3-bolt or 5-bolt top mounts, EDC (electronic dampers) or not, and coupe, convertible or Gran Coupe.

Not sure what your car has? Call 1-800-460-9106 with your VIN.

Animated illustration. It shows where coilovers sit on a car, not your exact kit. Depending on the car and the kit, coilovers can lean forward or back or stand straight up, and some cars use a separate spring and shock in the rear. Your ride height depends on the kit and how it is set up.

Find your 4 Series or M4

Three things that decide which 4 Series kit fits

Check these on your car before you order.

Top mount bolts

BC sells 3-bolt and 5-bolt kits for the F32 and F82 M4, to match your top mount bolts. Fortune Auto does the same for the M4.

EDC or Adaptive M

KW and Solo-Werks sell separate kits for cars with EDC, and these come with a cancellation or delete kit. Ksport's F32 kit does not fit cars with EDC or M-Technik xDrive. BC's F82 M4 kit names also include "EDC"; ask us what that means for your car.

Body and drive

KW makes separate kits for coupe, convertible and Gran Coupe, and for rear drive or xDrive. BC's rear-drive F32 kits fit the coupe only.

BC Racing coilovers, F32 to G82

Fifteen BC kits across four generations

BC Racing makes kits for the BMW 4 Series and M4 in these series only: BR, DS, ER, RM, HM, ZR and ZX. HM and ZR come only on the two F82 M4 coupe kits. Free shipping on BC Racing kits in the continental US.

The seven BC series for the 4 Series

We carry every BC series for this car, from BR to ZX.

BR, DS and RM

BC Racing BR coilovers have one 30-click knob for both compression and rebound. DS is the same but adds a digressive piston for firmer control. RM is an inverted (upside-down) monotube built for MacPherson struts.

ER and HM

ER is an upright damper with an external reservoir (a separate oil canister) and its own 30-click knobs for compression and rebound. HM combines the RM and ER designs, so compression and rebound also adjust separately.

ZR and ZX

ZR has 30-click rebound, 15-click low-speed compression and 12-click high-speed compression. BC calls ZX its most track-tested series.

Before you buy: what 4 Series owners run into

Here is what 4 Series owners run into most, from owner forums, recalls and service bulletins, and what it means for your coilovers.

Rear camber and toe change when lowered
F82 and F83 M4, 2015 to 2020

A suspension maker says lowering the F82 M4 (and F80 M3 and F87 M2) sharply increases negative rear camber and toe-in. Specialists say the factory adjusters often give the camber or the toe you want, not both. A lowered M4 can run out of alignment range, causing uneven tire wear and a less stable rear.

Before you install: Plan the alignment with the install, and budget for adjustable rear toe or camber arms if the car will be dropped a lot or tracked.

Camber limits on a lowered F32
F32, F33 and F36 (non-M), 2014 to 2020

On Bimmerpost, a lowered F30 owner reports inner edge front tire wear that shops could not align out, since front camber has no factory adjustment. A lowered 435i owner reports maxing out the stock rear camber adjustment and fitting front camber plates. A lowered 4 Series can carry more camber than stock adjusters correct.

Before you install: For more than a mild drop, pick a kit with camber plates or plan for camber parts, and recheck the alignment after the install.

4 Series history

How the coupe got its own model line

At the 2013 launch, BMW wrote that the 4 "headlines this new product line for the Coupe."

  1. Design
    Close to the 3 Series"It is unmistakably the 3 Series' sibling, although the differences are apparent."
  2. 50:50
    Weight balance"It also has a 50:50 weight distribution, which sets it apart from its competitors."
  3. Ride height
    Center of gravityBMW said its lower suspension brings the car's center of gravity "down to below 20 inches (500 mm)."

Questions about bolts, EDC and body style

Do I need the 3-bolt or the 5-bolt kit?

Count the bolts on top of a front strut mount. BC names its kits by bolt count, and so does Fortune Auto for the M4. BC's 3-bolt and 5-bolt year ranges overlap, so count the bolts instead of going by year.

My car has EDC or Adaptive M Suspension. What fits?

KW sells kits for cars with EDC or Adaptive M that include cancellation, and Solo-Werks sells with-EDC kits that include a delete kit. Ksport's F32 kit does not fit cars with EDC or M-Technik xDrive. BC's two F82 M4 kits have "EDC" in their names; call us to confirm what that means for your car.

Is there a BC kit for a rear-drive G22 coupe?

No, not in the kits we carry. BC's G22 kit is AWD, and its rear-drive G26 kit is for the Gran Coupe.

Which BC kits come in HM and ZR?

Only the two F82 M4 coupe kits, 3-bolt and 5-bolt. HM and ZR come with Swift Springs included for most cars.

Are there convertible and Gran Coupe kits?

Yes. KW and Solo-Werks make kits for both. BC makes M4 Cabrio kits, and its 5-bolt xDrive kit name includes the F36.

What warranty comes with BC's BMW 4 Series coilovers?

BC Racing North America currently lists a two-year limited warranty on full kit orders, subject to its warranty terms. Each other brand sets its own.
