Audi Q8 4MN.
The coilover guide.
Shop the coiloversThe Q8 already has the broad shoulders and sloping roof for a restrained wheel-and-height change. Before choosing the stance, identify its suspension. Steel springs can still come with electronic damping, while air-sprung cars need a separate installation check.
A wider stance. A lower roof.
Start with how the car earns its miles. A Q8 that carries passengers and luggage needs working clearance with that load aboard. Settle the wheel and tyre package before agreeing the height.
The current listing here is BC Racing S-61 for Q8 AWD, type 4MN, from 2019 onwards. Its application row does not explain how every factory suspension system is handled. Have the exact equipment and fitting requirements checked before ordering.
Audi introduced the Q8 in 2018 as a more coupe-shaped alternative within its large SUV range. Its broad octagonal grille, sloping roof and pronounced wheelarches gave it a different outline from the taller Q7. Those proportions suit a careful wheel upgrade without needing an extreme drop.
Audi’s introduction described a body that was shorter, wider and lower than the contemporary Q7, with frameless doors and a full-width rear-light design. On a modified example, check that the chosen wheel width and offset leave room for steering and suspension movement.
Underneath, the Q8 uses five-link suspension at both ends. Audi’s chassis training illustrates the steel rear spring on its own seat beside the damper, while the front spring surrounds its damper. Ask the installer which supports are supplied or reused and how the front and rear height settings work.
Factory suspension needs particular attention. Audi described steel springs with electronic damping as well as adaptive air suspension, with equipment varying by version and market. Steel springs alone therefore do not identify a car without electronic controls. Record the fitted system rather than judging it from a trim badge or the drive-select screen.
Audi revised the Q8 in 2023, changing the grille, bumper detailing and lighting choices. The same update described steel suspension with damper control and optional adaptive air, while the SQ8 had its own equipment specification. A newer front end is not evidence that a particular replacement kit fits.
BC Racing names the current reference S-61, Q8 AWD, 4MN, from 2019 onwards. Keep that application separate from the Q7 and the electric Q8 e-tron. SQ8, RS Q8, plug-in versions and cars with uncertain equipment need an individual check; a general model row cannot resolve those details.
For a road build, put wheel clearance, normal loads and a sound installation ahead of the last few millimetres of lowering. Worn joints or bushes can spoil the result before a damper setting enters the conversation. Agree the finished height with the installer, then align the car at that height.

The listed Q8 AWD application
S-61 names Q8 AWD, type 4MN, from 2019 onwards. The current BR RS listing specifies rubber top mounts front and rear and nominal 11 kg/mm springs at both ends. Confirm the exact vehicle, factory suspension and current installation requirements.
Check the S-61 application
Electronic damping or air suspension
A steel-sprung Q8 can have electronic damper control. Identify that equipment and agree how the replacement hardware affects it. Air suspension needs a separate check: the general S-61 row does not establish an air-to-coil conversion or retained electronic functions.
Ask about the suspension equipment
Facelift, SQ8, RS Q8 or hybrid
Use the exact engine, chassis, axle loads and suspension codes for a derivative check. Facelift styling, a shared body or an AWD badge cannot establish the required hardware. The electric Q8 e-tron is a different vehicle and is not included by this application.
Check the exact Q8
An already modified Q8
Bring wheel widths, offsets, tyre sizes and spacer measurements, with details of brake or suspension changes. Have the current hardware identified, including any previous air conversion. Check clearance with the normal load and through the full working movement.

S-61 BR RS is the current listed example for Q8 AWD 4MN. Have the factory spring and damping equipment checked against the exact instructions before treating it as your order. Agree the complete fitting parts and the clearance checks, then plan alignment at the finished height.
- Identify springs and electronic controls
- Confirm the S-61 installation
- Leave clearance for ordinary loads
Discuss the intended event and vehicle preparation before choosing the suspension.
Read the buying advice
Tell the people preparing the car about its tyres, brakes, weight changes and intended sessions. A road-model application alone does not establish a tested circuit setup for a large SUV. Agree that preparation brief and inspection plan before deciding the hardware.
- Describe the event and intended use
- Check brakes, tyres and clearance
- Agree preparation and inspections
Use the finished car and its intended use to agree a complete specification.
Read the buying advice
Different mounting arrangements, substantial weight changes or dedicated tyres need an individual assessment. Record those changes and the electronic systems still fitted. Have the hardware and setup agreed for the finished build and its intended use.
- Measure the finished vehicle
- Agree mounting and control requirements
- Plan setup and follow-up checks
A separate rear spring and damper.
On a standard Audi Q8 with steel springs, the rear spring and damper are mounted separately.
Component layout only. Mounts, dimensions and adjusters vary by kit.Audi’s Q8 chassis training shows a five-link rear axle with the steel coil on its own inboard seat beside the damper. At the front, the spring surrounds the damper. A broad coilover description should not be read as the same physical adjustment at all four corners.
This compact drawing identifies the steel rear component positions. It does not show the supplied S-61 hardware or an air conversion. Confirm the front and rear parts, spring supports and reused components in the current fitting instructions.
Understand height and spring preload
Know the equipment before the fitting day
Have the original suspension identified, then compare it with what is on the car now. On a used Q8, a previous conversion or an undocumented damper change can matter as much as its registration year. Record the electronic controls and any warnings already present.
Agree the installation parts and the effect on the fitted systems before booking. Check worn supporting components and wheel clearance as part of that plan. Finish with alignment at the settled working height and the installer’s follow-up checks.
Choose wheels as a package
Check wheel width, offset, tyre size and spacers together. Include brake clearance and have the fitter check steering and suspension movement at the intended height.
Identify the control systems
Record electronic damping, air suspension and rear steering before choosing parts. Agree what the exact installation changes and what equipment remains functional.
Allow for passengers and luggage
A static arch gap with an empty boot is only one measurement. Leave usable suspension movement for the load the Q8 normally carries and the roads it uses.
Inspect before fitting
Check mounts, bushes, joints and alignment adjusters while planning the work. Agree supplied and reused components, alignment and the installer’s follow-up inspection.

Questions about Audi Q8 4MN coilovers.
Check the details before choosing your kit.
Which Q8 is the listed kit for?
The current BC Racing S-61 row names Q8 AWD, type 4MN, from 2019 onwards. Check the exact chassis, engine, loads and factory suspension against the current fitting instructions. That model row does not separately approve every derivative or equipment combination.
Do steel springs mean the Q8 has no electronic damping?
No. Audi describes steel-spring Q8 suspension with electronic damper control. Identify the actual equipment and agree how the replacement kit affects those functions. A steel spring or a drive-select menu alone is not enough to settle the fitting requirements.
Is the rear spring separate from the damper?
On the steel-sprung Q8, yes. Audi’s chassis training shows the rear coil on its own seat beside the damper in a five-link rear axle. The compact illustration describes that component layout, not the contents of a particular kit.
Does S-61 convert factory air suspension to coils?
The general Q8 application row does not establish that. Have an air-sprung car or a previous conversion checked separately, including the required hardware and effect on control systems. Do not assume a spring-and-damper listing includes conversion parts or coding.
What is the current BR RS specification?
The current S-61 listing specifies rubber top mounts front and rear and nominal 11 kg/mm springs at both ends. Confirm the exact configuration and current instructions before ordering. The spring figures do not establish universal fitment or a circuit setup.
Does the listing also approve SQ8, RS Q8 or Q8 e-tron?
Do not infer that from the Q8 name. SQ8, RS Q8, plug-in and facelift equipment questions need an exact derivative check. The electric Q8 e-tron is a separate vehicle and is not covered by this Q8 4MN application.
What should I measure before lowering the car?
Record wheel widths, offsets, tyre sizes and spacers, plus brake changes and the usual load. Have clearance checked through steering and suspension movement at the proposed height. A photograph of the arch gap cannot establish those clearances.
When should alignment and fitting be booked?
Confirm current supply timing and the complete installation requirements first. Arrange alignment after the car is settled at the agreed working height, with any supporting repairs completed. Follow the installer’s inspection and recheck instructions.
Let’s talk suspension.
Find your Q8, then tell us which suspension it originally had and what is fitted now. Add the engine, electronic equipment, wheel and tyre details and any previous changes so the exact application can be checked.
