Audi Q7 4M.
The coilover guide.
Shop the coiloversThe sharper 4M looks good on a considered wheel upgrade and a modest drop. Start underneath the car: the current BC Racing application is for the Q7 AWD without electronic damping. Ask us to check a car with factory air suspension before choosing a kit.
A sharper shape. A different chassis.
A Q7 still has to work when the family and luggage are aboard. Choose the wheel and tyre package with that load in mind, then agree a height that leaves the suspension room to move on your normal roads.
There is one current 4M listing here: BC Racing S-54. Its without-EDC restriction matters more than whether the car has an early or facelift grille. Identify its original equipment before opening the configuration.
Audi launched the second-generation Q7 in 2015. The 4M kept the long, practical SUV format but changed the rounded outline of the first car for straighter shoulders, narrower lamps and a more angular grille. The shape gives a restrained wheel-and-stance build a clear starting point.
The changes extended beneath the body. Audi’s chassis training describes five-link suspension at both ends, replacing the earlier Q7’s double-wishbone arrangements. At the steel-sprung rear, the coil moved to a seat beside the damper. The old 4L’s combined rear unit is not the layout to copy when discussing a 4M.
The cabin remained a large part of the appeal. Audi’s second-generation introduction described more interior room despite slightly smaller external dimensions, with seating arrangements varying by market and specification. When setting the height on a family car, allow for how those seats and the luggage space are actually used.
The first major appearance update arrived in 2019. Audi later revised the Q7 again, describing new lighting and exterior details in its January 2024 release. Those changes help date a body style; they do not tell you whether it has steel springs, adaptive air or the exact equipment required by a suspension listing.
Audi offered standard steel springs with unregulated damping as well as air suspension with electronic damper control. All-wheel steering was another available system. A trim badge, large wheels or a drive-select menu is not enough information to approve a replacement kit for an individual car.
BC Racing’s current S-54 application names the 4M Q7 AWD without EDC from 2016 onwards. Check those details against the chassis and fitted equipment. The date range does not approve a different Q7 generation or a car with electronically controlled suspension.
For a visual upgrade, settle wheel width, offset and tyre size before chasing the smallest arch gap. Include spacers, brake changes and the car’s usual loads. Have the finished package checked through steering and suspension movement, then aligned at the agreed height.
Start with your Q7 4M.
Confirm the chassis, year and existing suspension before choosing your setup.
Steel springs, without electronic damping
The current S-54 row names Q7 AWD, type 4M, from 2016 onwards without EDC. The published BR RS specification uses rubber mounts at both ends and nominal spring rates of 10 kg/mm front and 11 kg/mm rear. Check the exact car, its equipment and the current fitting instructions.
Check the S-54 application
Original air or electronic suspension
Identify the factory suspension before choosing the kit. S-54 is listed without electronic damping; it is not described as an air-to-coil conversion. A car on adaptive air, electronically controlled dampers or a previous conversion needs an exact equipment and installation check.
Ask about the fitted suspension
Facelift, SQ7 or hybrid questions
A later front end does not establish the suspension specification. Have the exact chassis, engine, axle loads and equipment checked for a facelift car, SQ7 or plug-in variant. The broad 4M row does not separately establish approval for all of them.
Check the exact vehicle
Wheels, loads and previous changes
Bring the wheel widths, offsets, tyre sizes and spacer measurements, plus details of brake changes and normal loads. If the suspension has already been altered, identify the parts now fitted. Its current arch gap cannot show the clearance available throughout suspension movement.

S-54 BR RS is the current option for the matching Q7 4M AWD without electronic damping. Confirm that equipment restriction and the complete installation parts before ordering. Agree the height around the chosen tyres and usual load, then arrange alignment on the finished car.
- Identify the original damping system
- Match the exact S-54 application
- Keep clearance for normal loads
Discuss the vehicle and event before treating a road application as a circuit choice.
Read the buying advice
Explain the intended event, tyres, brakes and weight changes to the people preparing the car. A large SUV needs a preparation brief for that use. The current model listing alone does not establish a tested or approved circuit specification.
- Describe the event and intended use
- Check brakes, tyres and wheel changes
- Agree preparation and inspection
Use the finished car’s measurements and intended use to write the suspension brief.
Read the buying advice
A changed mounting arrangement, different vehicle weight or dedicated tyres can require a different specification. Have the hardware, spring choice and setup agreed for that build. Describe the finished car and its intended events when making the enquiry.
- Measure the finished vehicle
- Confirm mounting and control requirements
- Plan setup and follow-up checks
A separate rear spring and damper.
On a standard Audi Q7 4M with steel springs, the rear spring and damper are mounted separately.
Component layout only. Mounts, dimensions and adjusters vary by kit.The steel-sprung 4M has a rear coil on its own inboard seat beside the damper, within a five-link rear axle. Audi’s chassis training shows the separate components. This differs from the earlier 4L, whose steel rear spring surrounds the damper.
The compact drawing identifies those steel-spring component positions. It does not specify the supplied kit hardware or describe an air conversion. Confirm how the exact S-54 parts, supports and reused components fit the car; do not assume a lower-bracket adjustment at every corner.
Understand height and spring preload
Start with the equipment already fitted
Before ordering, have the original suspension identified and compare it with the parts now fitted. This matters on a used Q7 with an uncertain modification history. Check the electronic-damping restriction against actual equipment rather than an exterior badge or the registration year.
Inspect mounts, joints and bushes while planning the installation. Agree the supplied and reused parts, the wheel-clearance checks and the working height. Finish with alignment and a follow-up inspection; a kit listing cannot replace that plan for the individual car.
Measure the wheel package
Check width, offset, tyre size and spacers together. The fitter needs to check arch, brake and suspension clearance through steering and suspension movement at the intended height.
Allow for the way it is loaded
Plan around the people and luggage the Q7 normally carries. A height chosen with an empty boot still needs enough movement for ordinary use with the car loaded.
Identify the equipment first
Confirm steel springs and the absence of electronic damping for the S-54 application. Record air suspension, rear steering and any previous changes so their effect on the exact installation can be checked.
Check the supporting parts
Inspect mounts, bushes, joints and alignment adjusters before fitting. Agree supplied and reused components, then arrange alignment and the installer’s follow-up inspection at the chosen height.

Questions about Audi Q7 4M coilovers.
Check the details before choosing your kit.
Which Q7 does this guide cover?
The second-generation Audi Q7, type 4M. The current BC Racing S-54 application names Q7 AWD from 2016 onwards without electronic damping. Check the chassis and equipment rather than assuming every Q7 registered after that date uses the same kit.
Does the 4M rear spring sit around the damper?
On the steel-sprung 4M, the rear coil sits separately beside the damper within a five-link axle. Audi’s chassis training shows the arrangement. The earlier 4L has a different steel rear layout, with the spring around the damper.
What is the current S-54 specification?
The current listing is BR RS with rubber top mounts front and rear, and nominal spring rates of 10 kg/mm front and 11 kg/mm rear. Confirm the exact vehicle and current fitting instructions; those figures do not establish a complete installation plan or universal engine approval.
What does without EDC mean for ordering?
The maker’s application excludes electronic damping. Identify the actual factory suspension and check that restriction before ordering. A drive-select menu or trim badge alone does not establish whether the individual car matches.
Is S-54 an air-to-coil conversion kit?
It is listed for the Q7 4M without electronic damping, not as an air-to-coil conversion. Have a car with adaptive air or a previous conversion checked separately. Do not transfer the earlier 4L S-37 conversion application to a 4M.
Does the listing cover every facelift, SQ7 or hybrid?
The general 4M application does not separately establish every engine, facelift specification, SQ7 or plug-in variant. Check the chassis, axle loads, factory suspension and current instructions for the exact car. Exterior styling changes are not equipment or fitment proof.
What should I measure before lowering my Q7?
Record wheel width, offset, tyre size and spacers, with details of brake changes and normal loads. Have clearance checked through steering and suspension movement at the proposed height. An empty car’s static arch gap is only one part of that check.
Is height adjusted in the same way at every corner?
Do not assume that from general coilover wording. The 4M’s steel rear spring and damper are separate. Read the exact S-54 instructions and confirm its front and rear components and adjusters with the fitter before deciding the setup.
Let’s talk suspension.
Find your Q7, then tell us its original suspension and what is fitted now. Include the engine, electronic-damping equipment, wheel and tyre details and any previous changes so the exact reference can be checked.
