Lowering Springs for BMW

The G20-generation 330i, 330i xDrive and M340i share the same CLAR-platform strut and spring design, so one H&R kit covers most trims with the drop amount changing based on which factory suspension the car left the plant with. H&R's Sport Springs (28662-1 for RWD, 28662-2 for xDrive) drop a 330i without M Sport suspension about 1.6" front and 1.5" rear. The same spring part on a car that already has factory M Sport or adaptive dampers settles closer to 1.1"-1.2" at both ends, because the M Sport shocks are shorter to start with and leave less travel to take up.

M340i models come only with M Sport suspension from the factory, so they land in that smaller 1.1"-1.2" range rather than the full 1.6" quoted for base non-sport 330i cars. Owners coming from the older E9x 3 Series who want adjustable ride height instead of fixed-rate springs can compare options on the E9x coilovers page.

Eibach's Pro-Kit for the G80 M3 sedan (RWD) drops the front 25mm (1.0") and rear 13mm (0.5"), and is engineered to work with the factory OE shocks and bump stops rather than requiring a shock swap. The Competition xDrive version uses a shorter 20mm front spring (part E10-20-049-10-22) to offset the added weight of the all-wheel-drive front-axle hardware, landing around 0.8" front and 0.5" rear.

On the G82 M4 Competition xDrive coupe, Eibach's E10-20-049-09-22 kit drops about 0.9" front and 0.5" rear. The noticeably smaller rear drop on both the M3 and M4 kits is intentional: the G8x chassis loses rear camber quickly once the rear ride height comes down, so Eibach keeps the rear closer to stock to protect tire wear and rear-end grip. See coilovers vs. lowering springs if you want rear height to be adjustable instead of fixed.

On the current G30 5 Series, Eibach's Pro-Kit (E10-20-038-01-22) fits the 530i, 530i xDrive, 530e and 540i and drops the car close to an inch front and rear, but it explicitly excludes cars with factory EDC electronic damper control; those need a kit built around adaptive dampers instead. On the previous-generation F10 (2011-2016), Eibach's Pro-Kit for the 528i xDrive and 535i xDrive quotes a 1.2" drop, while H&R's Sport Spring sets for the F10 are commonly listed around 1.4" front and 1.3" rear depending on the exact trim.

Because the F10 ran for five model years with several suspension revisions (standard steel springs, M Sport, Dynamic Damper Control, self-leveling rear air on some Touring and xDrive variants), always match the part number to your car's build rather than assuming one F10 kit covers every 535i.

H&R's Sport Springs for the G01 X3 xDrive30i and X3 M40i with factory M Sport suspension (part 28926-1) drop the front 1.4" and the rear 0.8", a bigger front-to-rear split than the sedans because of the X3's higher factory ride height and front overhang. For the G05 X5, H&R's lowering springs (28634-2) drop around 1.0" (35mm) front and rear on xDrive40i, 50i and M50i models, with a different-rate variant for cars carrying heavier front-axle loads.

Some X5 trims come with self-leveling air springs at the rear instead of steel coils; steel lowering springs cannot be installed on those cars. If your X5 has rear air suspension, check the air suspension guide before shopping for a lowering spring kit.

Any amount of drop on a BMW changes camber and toe, so budget for a full alignment right after install, not just a toe check. On 3 Series and M3/M4 cars that go past about an inch of front drop, the factory camber adjustment range often runs out; aftermarket camber/caster plates or camber bolts bring it back into an alignment-friendly range on cars that need more negative camber than stock hardware allows.

Staggered factory wheel and tire packages generally clear a 1"-1.5" drop on sedans without rubbing, but X3 and X5 owners running larger aftermarket wheels should check fender liner and strut-to-tire clearance at full steering lock before committing to a kit. A spring compressor or spanner wrench makes the spring swap itself straightforward; the install guide below covers the labor side in more detail.
