Eibach E10-20-049-10-22 PRO-KIT Lowering Springs

The Eibach PRO-KIT E10-20-049-10-22 is a complete set of four progressive-rate lowering springs built specifically for the 2021-2026 BMW M3 Competition xDrive (G80) with the 3.0L TT S58 inline-6. This is the AWD xDrive-specific application. If you own the rear-wheel-drive G80 M3, stop here and look at a different part number. The E10-20-049-10-22 drops the front of your G80 approximately 0.8 inches (20mm) and the rear approximately 0.5 inches (13mm) using Eibach's signature progressive spring rate technology, all while retaining your factory OE dampers. No shock replacement required.

Made in the USA by Eibach, Inc. in Corona, California. Backed by Eibach's 5-Year Limited Lifetime Warranty against defects in materials and workmanship.

Why the Eibach PRO-KIT E10-20-049-10-22 Outperforms Stock BMW Springs

The G80 M3 Competition xDrive leaves the factory with a ride height tuned for global markets, ride comfort, and regulatory clearance requirements, not for optimal corner entry, visual stance, or dynamic performance. The springs are deliberately softened to accommodate a wide range of road conditions and driver preferences. The result is excess body roll, understeer on-ramp, and a wheel-gap-to-tire-contact-patch ratio that leaves serious driving performance on the table.

The E10-20-049-10-22 corrects this with a progressive spring rate design. Progressive rate means the spring stiffness increases as the spring compresses. Under light loads and normal street driving, the spring rate stays compliant. As cornering forces build, the spring stiffens progressively, resisting body roll and improving turn-in response. This is fundamentally different from a linear drop spring that simply trades ride comfort for handling. The Eibach PRO-KIT gives you both: a lower, more aggressive stance and improved handling dynamics without turning your M3 into a track-only car on street roads. The E10-20-049-10-22 was engineered and validated to work directly with the G80 M3 xDrive's factory Adaptive M suspension dampers, meaning no recalibration, no compatibility concerns, and no voided adaptive damper functionality.

Progressive Rate Spring Technology

Most aftermarket drop springs use a linear spring rate: constant stiffness from full extension to full compression. Linear springs force you to choose between a drop and a ride quality you can live with. Eibach's PRO-KIT takes a different approach. The E10-20-049-10-22 uses a variable coil pitch design. The coils are wound closer together at one end and progressively farther apart toward the other. Under light compression, only the widely spaced coils are active, delivering a softer, compliant response. As the spring compresses further under hard cornering or braking, the closely wound coils begin to contact each other and go inactive, leaving only the stiffer coils working. The effective spring rate rises exactly when you need it, and stays soft when you don't. This is why the PRO-KIT has a 30-year track record in motorsport-adjacent street applications across virtually every performance platform, including the full G80 M3 lineup.

Drop Heights and What They Mean for Your G80 M3 xDrive

The E10-20-049-10-22 lowers the front of the G80 M3 Competition xDrive approximately 0.8 inches (20mm) and the rear approximately 0.5 inches (13mm). The asymmetric drop is intentional. The G80 M3 xDrive runs a front-biased weight distribution and the front suspension geometry benefits from a more aggressive correction. The slightly more modest rear drop preserves the factory rear squat behavior under hard acceleration, which is critical on an AWD platform where rear traction on launch matters. The net result is a stance that reads "purpose-built" rather than "dragged," with a lower center of gravity that directly improves lateral g-force handling. Your M3 will corner flatter, enter turns with more confidence, and look exactly the way the factory styling team intended before clearance engineering forced the ride height up.

Important: After installation, Eibach requires a professional four-wheel alignment. Drive approximately 50 miles before the final alignment appointment to allow the suspension to fully settle. Aligning immediately after installation before the springs have seated can result in alignment figures that drift post-settling.

AWD xDrive Fitment vs. RWD, and Why the Part Numbers Are Different

This is the most important fitment distinction for the G80 M3: the AWD xDrive and RWD versions use different Eibach PRO-KIT part numbers and produce different drop heights.

The E10-20-049-10-22 is engineered exclusively for the AWD Competition xDrive G80 M3. The front subframe geometry, suspension pickup points, and weight distribution of the xDrive differ from the RWD car due to the front differential, front driveshafts, and additional drivetrain mass. Eibach accounts for these differences in the spring rate calibration and the target drop heights. The RWD G80 M3 uses a different part: E10-20-049-11-22. That kit drops the front 1.0 inch (versus 0.8 inches for xDrive) and uses spring rates calibrated for the lighter, rear-biased RWD platform. Installing the RWD kit on an xDrive car, or vice versa, will produce incorrect drop heights and suboptimal handling characteristics. Always confirm your drivetrain before ordering.

Fitment, 2021-2026 BMW M3 Competition xDrive (G80)

E10-20-049-10-22 fits the BMW M3 Competition xDrive sedan (G80) with the 3.0L TT S58 inline-6 engine and AWD drivetrain only. This kit does not fit the RWD M3, the G81 M3 Touring wagon, or the G82/G83 M4. Each model year listed below has been confirmed by Eibach's EPS application search as of June 2026. Confirm your drivetrain is AWD/xDrive before ordering.

Compare: AWD xDrive (E10-20-049-10-22) vs. RWD (E10-20-049-11-22) vs. Front-Only (E10-20-049-10-20)

Eibach offers multiple PRO-KIT configurations for the G80 M3 family. Here is how they compare:

The front-only kit (E10-20-049-10-20) is designed for xDrive owners running staggered wheel fitment who are replacing only front springs. Most customers with a standard square wheel setup should purchase the full set (this kit, EIBE10-20-049-10-22) for a balanced, calibrated front-to-rear drop.

Installation Overview

Installing the E10-20-049-10-22 is a spring swap, not a full suspension rebuild. However, the G80 M3 xDrive front suspension requires more care than a typical strut car due to the front driveshafts. Plan for a shop or experienced DIY install with proper spring compressors. A professional alignment is required after installation.

• Tools required: spring compressor, torque wrench, socket set, BMW ISTA or equivalent for any stored fault codes post-install
• Retain all factory OE spring isolators and dampers from your stock springs
• Mark the orientation of the upper strut perch relative to the lower perch before disassembly (MacPherson strut front), and maintain that orientation during reassembly
• Install all springs with the Eibach logo facing right-side up
• For the xDrive front: handle the front driveshafts carefully during strut removal and reinstallation
• Front strut tower bolts: 28 Nm plus 180 degrees; front strut top nut: 71 Nm; strut pinch bolts: 56 Nm
• Rear lower control arm main bolt: 100 Nm plus 90 degrees; rear shock top nut: 38 Nm
• Drive approximately 50 miles after installation before scheduling your alignment appointment
• After settling, perform a professional four-wheel alignment per Eibach installation instructions
• Verify brake line clearance, ABS sensor clearance, and tire-to-fender clearance after installation

Full installation instructions are included in the box as Eibach Instruction Sheet D4170. A PDF version is available directly from Eibach at eibach.com/storage/instructions/D4170.pdf.

About Eibach

Eibach has been engineering performance springs since 1951. Their PRO-KIT line is the most widely used performance lowering spring in the world, spanning nearly every performance platform across every major manufacturer. Eibach's engineering approach is data-driven: each PRO-KIT application is developed on that specific vehicle with that specific suspension geometry, not adapted from a similar platform. The G80 M3 xDrive kit (E10-20-049-10-22) was developed and validated on the G80 M3 xDrive specifically. Eibach's US operations are based in Corona, California, where the US-spec PRO-KIT springs are manufactured. The Eibach name carries genuine engineering credibility in the BMW M community, with strong real-world validation across multiple M3 generations dating back to the E36.

Frequently Asked Questions

I have a G80 M3 but I am not sure if it is xDrive. Does the E10-20-049-10-22 fit my car?
The E10-20-049-10-22 (Eibach MPN E10-20-049-10-22) fits the AWD xDrive G80 M3 Competition only. If your M3 is rear-wheel drive, this is the wrong part. Check your window sticker, the vehicle label in the driver door jamb, or your BMW ConnectedDrive account. The xDrive designation will be clearly listed. The RWD G80 M3 uses Eibach part E10-20-049-11-22, which is sold separately.

How much does the E10-20-049-10-22 lower the G80 M3 xDrive?
The front drops approximately 0.8 inches (20mm) and the rear drops approximately 0.5 inches (13mm). These figures are per Eibach's published specifications for the E10-20-049-10-22. The asymmetric drop is intentional, optimized for the xDrive platform's weight distribution and suspension geometry.

Do I need to replace my shocks or struts when installing the E10-20-049-10-22?
No. The Eibach PRO-KIT E10-20-049-10-22 is designed and tested for use with your factory OE dampers. Your stock struts and shocks are retained. Eibach explicitly states the kit was tested with factory dampers. You do not need to purchase new shocks. If your factory dampers are already worn or out of specification, you should address that separately, but the spring kit itself does not require a damper upgrade.

Is a wheel alignment required after installing the E10-20-049-10-22?
Yes, a professional four-wheel alignment is required after installation. Lowering the ride height changes the suspension geometry, including camber and toe settings. Driving on incorrect alignment will cause uneven and accelerated tire wear. Eibach's installation instructions explicitly call for a post-install wheel alignment. Important: drive approximately 50 miles after installation before getting the alignment. This allows the springs to fully settle. An alignment performed before settling may drift slightly after the suspension compresses into its final position.

What is included in the E10-20-049-10-22 box?
The kit includes four progressive-rate lowering springs (two front, two rear) and Eibach's installation instruction sheet (D4170). No new hardware is included and none is needed. Your factory spring isolators and dampers are reused from your existing stock springs. No additional parts purchases are required to complete the installation.

What is the warranty on the Eibach E10-20-049-10-22?
Eibach covers the E10-20-049-10-22 with a 5-Year / Limited Lifetime Warranty against defects in materials and workmanship under normal use conditions. Coatings are excluded. The warranty covers the original purchaser only. Under the federal Magnuson-Moss Warranty Act, this aftermarket suspension upgrade cannot void your BMW factory warranty unless BMW can prove a direct causal link between the spring and any specific claimed failure.

Will the EIBE10-20-049-10-22 void my BMW M3 factory warranty?
No, not automatically. The federal Magnuson-Moss Warranty Act prohibits a manufacturer from voiding your warranty simply because you installed an aftermarket part. BMW must demonstrate that the specific aftermarket part directly caused the specific failure being claimed. Aftermarket lowering springs installed within their intended use parameters do not void your BMW powertrain warranty, engine warranty, or most other warranty coverage. If BMW attempts to deny a warranty claim citing your spring installation, that denial must be accompanied by proof of causation, which is a high bar for a part as standard as a drop spring.

How long does it take to install the E10-20-049-10-22?
An experienced independent BMW shop should complete the spring swap in 3 to 4 hours. The xDrive front suspension is more involved than the RWD version due to front driveshaft handling. Allow additional time for the alignment appointment, which should be scheduled after the initial 50-mile break-in drive. DIY installers with a lift, spring compressor, and familiarity with BMW suspension should plan for a full day to work comfortably without rushing.

What is the difference between E10-20-049-10-22 (xDrive) and E10-20-049-11-22 (RWD)?
Both are Eibach PRO-KIT full sets (4 springs) for the G80 M3, and both are priced the same. The difference is drivetrain and spring calibration. The E10-20-049-10-22 is for AWD xDrive only and drops the front 0.8 inches (-20mm) and rear 0.5 inches (-13mm). The E10-20-049-11-22 is for RWD only and drops the front a slightly more aggressive 1.0 inch with the same 0.5-inch rear. The spring rates are calibrated differently to account for the additional front drivetrain mass and weight distribution of the xDrive platform. Installing the wrong kit for your drivetrain will produce incorrect drop heights and mismatched spring behavior. Confirm your drivetrain before ordering.

Does the E10-20-049-10-22 fit the G81 M3 Touring or G82 M4?
No. The E10-20-049-10-22 fits the G80 M3 sedan with xDrive AWD only. The G81 M3 Touring uses a different kit (E10-20-049-08-22). The G82 M4 Competition xDrive uses E10-20-049-12-22. All three are different vehicles with different suspension geometry and different spring calibrations. Do not cross-apply these kits.

Is this product legal in California?
Yes. Lowering springs are not emissions-related components and do not require a CARB Executive Order exemption. The EIBE10-20-049-10-22 is legal to use in California and all 50 states. However, this product carries a California Proposition 65 warning: WARNING: Cancer and Reproductive Harm. www.P65Warnings.ca.gov.
