Coilovers for the BMW E9x (E90, E91, E92, E93)

For a 325i, 328i, 330i or 335i that sees daily driving with the occasional track day, BC Racing BR and ST Suspensions ST XTA cover the budget-to-mid range, with full height adjustment and front camber plates. Step up to KW V3 or Bilstein B16 for independently adjustable compression and rebound damping, which matters more once the car is pushed harder or lowered aggressively. Ohlins Road & Track is built around a single-knob Dual Flow Valve that keeps the ride usable on the street while giving a firmer setting for track days, at a noticeably higher price point than the BC Racing or ST Suspensions options.

Cars that came with Electronic Damper Control (EDC) need either an EDC-compatible coilover (KW V3 and Bilstein B16 Damptronic both offer EDC versions) or an EDC cancellation kit if the coilover doesn't support the factory module. Anyone comparing the trade-offs against a spring-only setup should read coilovers vs lowering springs first.

Non-M E90/E92 kits like KW V3 are specced with a front lowering range of roughly 30-60mm (1.2-2.4 in) and a rear range of 25-55mm (1.0-2.2 in), fully adjustable within that window rather than fixed. BC Racing BR and ST XTA sit in a similar overall range on the non-M chassis, with full threaded-body height adjustment front and rear.

The M3-specific ST XTA kit (E90/E92/E93 M3, 2008-2013) is tuned with a narrower, lower range given the M3's stiffer factory setup, with front lowering around 0.4-1.6 in and rear around 0.2-1.4 in. Bilstein's B16 Damptronic EDC for the M3 keeps the OE-style damper control intact while adding height adjustment, and its drop is generally kept modest to protect the M3's control-arm geometry.

Every coilover on this page needs a full alignment after install; the front camber plates included with BC Racing, KW and Bilstein Clubsport kits are there specifically to dial the extra negative camber back in once the car is lowered. The more the car is dropped, the more negative camber shows up at the front, and rear toe arms may need adjustable replacements to keep tire wear even past about 1.5 in of rear drop.

Wheel and tire clearance is car-specific: one E92 owner running a budget coilover reported needing a 10mm spacer to clear the fender after lowering, which is a common enough fix to plan for rather than a sign of a bad fitment.

E90 (sedan), E91 (wagon, mostly Euro-market), E92 (coupe) and E93 (convertible) share the same front and rear suspension pickup points, so a non-M coilover sold for the E90 325i/328i/330i/335i fits the E92 and E93 versions of those same engines. The M3 is a different platform underneath the shared body style: the S65 V8, a different front subframe and different control-arm geometry mean M3 coilovers are sold as their own part number and will not fit a non-M car, and vice versa.

xDrive (AWD) 328i and 335i models also need their own coilover, since the front strut has to clear the front differential and axle; BC Racing is one of the brands that lists a dedicated AWD BR kit alongside its RWD version.

Coilover installation on the E9x is not mechanically difficult but is labor-intensive; shops typically quote in the $400-$600 range including alignment, depending on whether the kit arrives pre-assembled. See coilover installation and cost for a general breakdown, and how to adjust coilovers once the kit is in and you're dialing in ride height. A spanner wrench is the one tool every threaded-body kit here requires for height adjustment.
