Audi S2 Coupé.
The coilover guide.
Shop the coiloversKeep the S2’s quiet shape and give the wheels room to work. Start with the actual Coupé, its suspension mounts and any earlier changes, then choose a height that suits the roads you drive.
The Coupé that started Audi’s S line
Choose the wheel-and-tyre package before the ride height. An S2 that looks settled in a side photograph still needs steering clearance and room to compress over a crest with passengers aboard.
The listed BC Racing reference here is S-16 for the 1990–1995 S2 Coupé AWD. Keep the Coupé application separate from the S2 Avant, saloon and RS2. Have a restored or converted car checked against what is fitted now.
Audi presented the S2 at the British International Motor Show in Birmingham in September 1990. It put a turbocharged five-cylinder engine and quattro into the rounded Coupé body, introducing the S badge to Audi’s production road cars.
The S2’s long doors, curved rear quarter windows and small tail spoiler give it a quieter outline than the boxed arches of the original quattro. A restrained wheel upgrade works with those proportions. Keep enough tyre sidewall and suspension movement for the way the car will be used.
The early car used a five-speed manual gearbox. Audi later raised the 2.2-litre engine’s output from 162 to 169 kW and paired the update with a six-speed gearbox. An engine or gearbox change may have happened again since then, so include those details when checking a used car’s application.
Audi also introduced an S2 Avant, and the name appeared on a saloon. Those bodies need their own parts checks. The BC reference on this page explicitly names the Coupé; a shared engine, quattro badge or supplier B4 label does not establish fitment for another body.
The Coupé’s original rear suspension uses struts with the coil springs around the dampers, lower wishbones and a subframe. Include the spring seats, upper mounts and lower strut attachments in the fitting plan. Match the replacement parts and retained hardware to the Coupé itself.
Before spending the fitting budget on adjustment options, have the existing bushes, joints, mounts and strut hardware inspected. Agree which supporting repairs belong in the same job. Set the working height around the tyres and road clearance, then have the finished geometry measured.

Confirm the chassis, year and existing suspension before choosing your setup.
1990–1995 S2 Coupé AWD
BC S-16 names this Coupé application. The current BR-RN listing specifies no front top mounts, rubber rear mounts and nominal 4 kg/mm front, 5 kg/mm rear springs. Confirm the exact build and current fitting requirements before ordering.
See the S-16 Coupé kit
Early or later build: identify what is there
Record the build year, engine and gearbox, including any swaps. The Coupé changed during production, and an earlier front end or later wheels cannot establish the suspension hardware underneath. Send the vehicle details with the fitting enquiry.
Check my S2 build
Restored, lowered or already converted
Have the existing struts, mounts and subframe hardware identified. Include previous coilovers, bush changes, brake upgrades and wheel spacers. A new kit needs to work with the finished car, including any parts that have already been altered.
Discuss the current setup
Avant, saloon or RS2: a separate check
This page’s kit reference names the S2 Coupé. Do not extend it to an estate, saloon, RS2 or ordinary Coupé conversion from the model name alone. Identify the exact body and running gear so the correct application can be investigated.
Ask about another bodyWhat do you want

Road miles, circuit weekends or a car built around the lap. Start with how you drive.
Keep the height usable on the roads you want to drive.
Read the buying advice
S-16 BR-RN is the listed Coupé example. Budget for inspection of the retained front mounts and bearings as well as the kit. Choose the height around the wheels, normal loads and clearance, then use the current instructions for the supplied hardware.
- Confirm the Coupé application
- Inspect retained mounts and bearings
- Leave useful road clearance
Plan the tyres, brakes and inspection routine together.
Read the buying advice
Bring tyre sizes, session plans and any weight or mounting changes to the enquiry. Agree the spring and damper specification with the people preparing the car, including an inspection routine between events. Keep a record of the finished height, alignment and damper settings for the next visit.
- Describe the intended sessions
- Check tyres, brakes and clearance
- Agree settings and follow-up checks
Specify the suspension around the finished build.
Read the buying advice
Record weight changes, tyre choice, mounting alterations and the competition use being planned. Have the required travel, spring specification and adjustment access agreed for that car. Historic competition paperwork does not approve a present-day kit or a road conversion.
- Measure the finished build
- Agree travel and spring requirements
- Plan setup and inspections
Rear springs around the struts.
The rear spring surrounds the damper on a standard Audi S2 Coupé.
Component layout only. Mounts, dimensions and adjusters vary by kit.The S2 Coupé’s original rear axle has a strut at each wheel, with its coil spring surrounding the damper. Lower wishbones and a subframe locate the assembly. This is a combined spring-and-damper position, rather than a separate coil on an inboard seat.
The compact drawing shows those component positions only. It does not specify the S-16 brackets, mounts or adjustment method. Use the current kit instructions and have the retained hardware checked; do not transfer the Coupé’s layout or parts to an Avant or saloon.
Understand height and spring preload
Inspect the old hardware before the new kit arrives
Have the current struts, mounting parts and supporting joints inspected before the fitting day. A previous restoration or suspension change may leave a different starting point from the registration details. Record the parts already on the car and agree what needs replacing.
Bring the actual wheel and tyre dimensions, spacer measurements and details of brake changes. Check clearance at the proposed height and allow useful movement for the load you carry. Arrange alignment once the car is settled at that working height.
Wheels, tyres and arch clearance
Record width, offset, tyre size and any spacers together. Check the inner clearance as well as the arch edge through steering and suspension movement. Include the clearance around changed brakes.
Retained mounts and strut hardware
The current RN listing supplies no front top mounts. Ask which mounts, bearings, fasteners and other supports are retained or replaced. A range photograph cannot identify the contents for your particular car.
Bushes, joints and subframes
Have the supporting components and mounting areas inspected before the fitting date. Agree any repairs with the installer so the new dampers are not being used to disguise play or damaged hardware.
Engine and drivetrain changes
Include engine or gearbox swaps and any changes to the running gear. The S2 Coupé application does not establish a suspension conversion for an ordinary Coupé, another body or a car assembled from mixed parts.

See the controls and hardware in the listed kit.
The current listed S-16 option is BR-RN for the 1990–1995 S2 Coupé AWD. It names no front top mounts, rubber rear mounts and nominal 4 kg/mm front, 5 kg/mm rear springs. Confirm the exact car, retained components and current fitting instructions. The rate figures alone do not establish a handling balance or circuit specification.

Questions about Audi S2 Coupé coilovers.
Check the details before choosing your kit.
Which S2 does the listed kit cover?
The current BC Racing S-16 row names the 1990–1995 S2 Coupé AWD. Confirm the exact build and current fitting requirements. The supplier’s B4 label is not approval for every Audi carrying that platform description.
Can I order this reference for an S2 Avant or saloon?
Do not infer that from the S2 name. The listed application explicitly names the Coupé. Avant, saloon, RS2 and ordinary Coupé conversions need their own exact body and running-gear check.
Do early and later S2 Coupés have the same gearbox?
No. The early car used a five-speed manual, while Audi’s later engine update came with a six-speed gearbox. Record what is fitted now, including swaps. That history does not by itself confirm the suspension parts on an individual car.
Is the Coupé’s rear spring separate from its damper?
No. The original S2 Coupé rear suspension has coil springs surrounding its struts, with lower wishbones and a subframe. The illustration describes those component positions, not the supplied contents of a particular kit or another S2 body.
Does the current RN kit include front top mounts?
The current S-16 BR-RN listing specifies no front top mounts and rubber rear mounts. Have the retained mounts and bearings inspected and confirm the complete parts requirement against the current instructions before ordering.
What spring rates are listed for S-16?
The current native listing gives nominal 4 kg/mm front and 5 kg/mm rear springs. Confirm the exact supplied specification with the order. Those figures alone do not prove a particular handling balance or suitability for your tyres and intended use.
How far should I lower an S2 on wider wheels?
Choose the height after checking wheel width, offset, tyre size and spacers. Have clearance measured at the inner suspension and outer arch through steering and suspension movement, including brake changes and the normal load. A static photograph cannot establish a safe lowering amount.
What should be included in the fitting budget?
Allow for the kit, fitting, alignment and any supporting repairs identified during inspection. Check mounts, bearings, bushes and joints before booking, and confirm current supply timing. Have alignment measured at the settled working height and follow the installer’s recheck plan.
