BMW 2 Series Coupe G42.
The coilover guide.
Shop the coiloversThe G42 combines a long bonnet, short boot and a choice of driven wheels. Give yours a useful stance by matching the engine, factory dampers and wheel clearance before choosing the kit.
The two-door G42, from launch to the 2024 update
The two-door G42 puts the 2 Series badge on a rear-drive-based coupe. A four-door Gran Coupe, an older F22 and the G87 M2 each need their own application checks.
BC Racing, AST and Eibach offer different routes through the current selection. Begin with the car you have: rear-wheel drive or xDrive, followed by passive or adaptive dampers and the precise engine.
BMW introduced the G42 in July 2021, with its public debut at Goodwood and the market launch following in 2022. The shape kept a long bonnet and a separate boot, with one main headlamp element on either side of a low grille. Four-cylinder rear-drive cars and the six-cylinder M240i xDrive gave the range distinct starting points.
The range expanded in July 2022 with the 218i and rear-wheel-drive M240i. An M240i badge alone therefore does not identify the driven wheels. Establish the market specification and actual build before using an application table.
BMW's 2024 update brought cabin and exterior revisions, with UK deliveries beginning that August. The UK range included rear-drive 220i and 230i models alongside the M240i xDrive. Passive M Sport suspension was standard on that M240i, with Adaptive M available as an option, so check the real equipment rather than assuming every six-cylinder car has electronic dampers.
The G42's pronounced rear shoulders suit a considered wheel change. Choose the width, offset and tyre together, then set the height around the clearance available. Keeping room for the wheel to move is more useful on a rough road than achieving a tight gap in a parked photograph.
For a car used throughout the week, allow for entrances, passengers and the roads on your regular journeys. Tell the fitter the height you want before choosing springs and setting the alignment. Keep a record of the finished measurements so later changes have a reference.
For circuit use, budget for tyres and brakes alongside the suspension. Choose damping controls you can reach and use, and agree who will help with the setup. A reservoir-equipped package also needs installation space and a servicing plan.

xDrive: identify the engine
BC I-160 names the G42 M240i AWD. AST lists 230i xDrive and M240i xDrive in its five AWD sets; Eibach -06 names M240i xDrive and excludes electronic suspension. These references do not approve every xDrive engine.
View named xDrive choices
Factory adaptive dampers
AST has separate EDC and NON-EDC application rows for its named 230i xDrive and M240i xDrive models. Confirm how the chosen kit handles the electronics and what functions or parts change. All three Eibach G42 references here exclude electronic suspension.

Confirm the rear hardware, reservoir placement and control access; the two-way 5200 is also listed if that adjustment package suits the build.
- Provide running weight and tyre plans
- Confirm reservoirs and control access
- Include servicing and setup time
A separate rear spring and damper
On a standard BMW 2 Series Coupe G42 factory-style rear, the rear spring and damper are mounted separately.
Component layout only. Mounts, dimensions and adjusters vary by kit.The factory G42 rear spring sits on its own seats beside a separate damper. A height-adjustable replacement can retain that arrangement, with the rear height adjustment at the spring unit. Check the instructions for the exact kit and axle.
AST uses NCO and TCO package references. Confirm the actual rear springs, seats, dampers, mounts and adjusters when specifying the set. The factory positions shown here do not establish every replacement package's rear construction or approve a conversion.
Understand height and spring preload
Check the actual car before fitting
Use the finder to identify the car, then add the engine, driven wheels and original damper details. Wheel dimensions, brake changes and earlier suspension work still need checking on the vehicle.
Agree the supplied and reused parts before booking. Set the intended height, check clearance and complete the alignment. Keep the measurements and settings so there is a known starting point for later adjustments.
Wheel clearance through movement
Check width, offset, tyre profile and spacers against the suspension and arches. Include full steering movement and the travel available at the intended height, with normal loads considered.
Brake and wheel shape
A wheel diameter does not establish caliper clearance. Check the actual spoke and barrel shape around the fitted brakes, including any larger brake package already on the car.
Adaptive equipment and kit contents
Identify passive or adaptive dampers from the actual build. Confirm the electronic changes, mounting parts and rear springs, seats and adjusters supplied or reused with the selected set.
Alignment after the height is set
Agree the finished ride height before final alignment. Include relevant sensor and headlamp checks, access to controls and a later settling and clearance check in the fitting plan.

Compare the controls and hardware included in each range.
I-160 names the G42 M240i AWD from 2021 onward. The current BR-RA option specifies pillowball front and rubber rear mounts. Confirm the exact spring and fitting package; this reference does not establish fitment for a rear-drive M240i or another G42 engine.
View BC Racing 2 Series Coupe G42 kits
Six references cover named rear-drive models and five cover the named xDrive models. Compare the 5100 packages, two-way 5200 and three-way 5300 by their supplied parts and controls. The ACS-B2021SD source descriptions disagree between 4100 and 5100: confirm its exact series and contents by part number before ordering. For EDC cars, agree electronic-function changes as well as fitment.

Before you order.
Identify your car
Identify G42, engine, build date and driven wheels. Keep the G87 M2 and other 2 Series bodies separate; a badge or registration year alone is insufficient.
Match the kit
Establish passive or adaptive dampers. Match the exact reference, named engine and axle-load limits, then agree any electronic-function changes.
Check what’s included
Confirm the actual rear package, mounts, springs and adjusters. Agree reused parts and access to any reservoirs or damping controls.
Check your modifications
Check wheel width, offset, tyres, spacers and brake clearance through steering and suspension movement at the proposed height.
Plan fitting
Plan fitting and final alignment, with relevant equipment checks. Confirm timing and include a settling and clearance recheck.
See what the adjustments do.
Choosing coilovers for road and track
Compare the kit against your roads, tyres and setup plans before counting adjusters.
Ride height and spring preload
Understand the two adjustments before choosing a lowering range.
What spring rate tells you
Compare force and movement, read the units and choose a spring with the damper in mind.
Spring rates and top mounts
Read the front/rear figures and check which mounts come with your kit.
Questions about BMW 2 Series Coupe G42 coilovers.
Check the details before choosing your kit.
Do these G42 kits fit the G87 M2?
The shared G42/G87 heading on some listings is not enough to establish M2 fitment. The exact application rows used here name particular G42 engines and driven wheels. A G87 M2 needs its own verified suspension reference.
Is every G42 M240i an xDrive car?
No. BMW added a rear-wheel-drive M240i to the international range in July 2022. Check the actual market specification and driven wheels. BC I-160 names M240i AWD, while AST and Eibach distinguish their rear-drive and xDrive applications.
Can I use these kits with adaptive dampers?
AST names EDC and NON-EDC rows for its G42 230i xDrive and M240i xDrive sets. Confirm how the exact package handles the electronics and which functions change. All three Eibach G42 references here exclude electronic suspension; their shared model heading does not override that condition.
Which Eibach reference is listed for my engine?
PSS65-20-045-01-22 names rear-drive 218i, 220i, 230i and 220d Mild-Hybrid; -02 names rear-drive M240i, and -06 names M240i xDrive. Their maximum axle loads are respectively 1030/1245, 1085/1245 and 1155/1260 kg front/rear. Check build date, original equipment and the exact certificate as well.
Are the G42 rear spring and damper separate?
Yes. The factory rear spring sits on its own seats beside the damper. A kit can retain that layout with a rear height adjuster at the spring unit. Confirm the exact replacement hardware; the factory arrangement does not prove every motorsport package uses the same construction.
What should I check with wider wheels and a lower ride height?
Check wheel width, offset, tyre profile and spacers against the inner suspension, brakes and outer arch. Include steering and suspension movement at the intended height. Allow for the loads you actually carry, and recheck clearance after fitting and settling.
Why does ACS-B2021SD need a series check?
The application header and current listing call it 5100, while the retained set description says 4100. Confirm the exact series and supplied contents by part number before ordering. The disagreement does not justify substituting another reference or assuming different hardware is included.
Should a road car always have the most adjustable kit?
Choose an application that fits and controls you have a plan to use. Extra damping circuits and reservoirs need installation space, access and setup support. Keep tyres, clearance and alignment in the decision; the purchase price alone does not establish which package suits your car.
Let’s talk suspension.
Find your G42, then add its engine, build date, driven wheels and original damper equipment. Include wheel and tyre sizes, brake changes and any previous suspension work so we can check the exact reference.
