Audi TT 8S.
The coilover guide.
Shop the coiloversThe final TT kept the compact shape and added a sharper face. Choose suspension around your exact engine, drivetrain and factory dampers, then leave enough clearance for the wheels you want to run.
The final TT, from virtual cockpit to five-cylinder RS
Decide how much clearance your wheels need before choosing a height for an 8S. Record wheel width, offset and tyre size, including spacers. The installer needs to check the inside of the wheel as well as the space beneath the arch.
Identify magnetic ride before replacing the dampers. A kit that removes electronic damping changes the suspension functions available to the driver. Agree that work with the installer rather than assuming a warning canceller retains the original system.
Audi introduced the third TT generation in 2014. Narrow headlights, a flatter grille and rings on the bonnet gave it a sharper face than the earlier 8J. Inside, the Audi virtual cockpit put instruments and infotainment in front of the driver, with the climate controls built into the air vents.
The 8S/FV family includes a Coupé and a two-seat Roadster. Keep the engine, drivetrain and roof style together in a suspension enquiry. FWD, quattro, TTS and TT RS applications have different limits even when they appear under the same product heading.
Audi presented the five-cylinder TT RS Coupé and Roadster in 2016. It has its own BC S-68 application, separate from the ordinary TT S-39 reference. A broad 2014–2023 table heading does not extend the TT RS application to earlier cars.
The front suspension uses struts, while the rear is independent with springs mounted separately from the dampers. Some replacement kits keep that rear arrangement; other configurations need their supplied layout and mounting requirements checked. Sharing a platform with another car is not a substitute for the exact TT application.
With wider wheels or larger brakes, build the suspension plan around the whole package. Leave room for steering, passengers and movement over the roads you use. A parked-car photograph cannot tell you whether the same height will work with your tyre dimensions.
For a circuit build, choose tyres and a working weight before agreeing springs and dampers. Remote reservoirs, adjustable mounts and setup support need space and time in the fitting plan. Extra adjustment is useful only if you can measure its effect on the car.

Start with your TT 8S.
Match the model year, engine and body style before comparing brands.
FWD: keep the front-drive reference
Eibach -01 explicitly excludes 4WD and names a 55 mm front damper. Its listed limits are 1,025 kg front and 845 kg rear, with 15–45 mm front and 20–45 mm rear lowering. Match the engine, original suspension and current certificate.
Compare FWD references
quattro: identify engine and roof style
Eibach -02 separates ordinary 2.0-litre quattro, TTS and TT RS lowering figures despite sharing a part number. Its current axle limits are 1,095 kg front and 920 kg rear. Keep the exact engine row and factory damper requirements with the order.
Compare quattro references
TTS and TT RS: different model checks
BC S-68 specifically names the 2016–2023 TT RS AWD; it is not a blanket TTS reference. The shared AST and MOTON tables also name TTS and TT RS, with 55 mm strut conditions. Have the actual set and body application confirmed.
See performance-model references
Magnetic ride or an altered TT
Include electronic damping, previous suspension changes and any running-gear conversion in the enquiry. Add tyre dimensions, spacers and brake changes. Confirm the replacement system and what remains adjustable from the cabin.
Check my TT setupWhat do you want
from the car?
Road miles, circuit weekends or a car built around the lap. Start with how you drive.
Choose a usable stance and leave room for the complete wheel package.
Read the buying advice
BC S-39 BR-RA is the ordinary TT FWD/AWD example to discuss. Its current option specifies pillowball front and rubber rear mounts. Confirm the exact car and any magnetic-ride replacement work, then allow for inspection, fitting and alignment.
- Identify engine, body and equipment
- Check the mounting parts
- Leave usable suspension movement
Choose the mounting arrangement before adding more adjustment.
Read the buying advice
AST ACT-V1903SD is the 5100 Street Performance example for the listed 55 mm 8S application. Its configuration retains a separate rear spring and damper. AST’s fitting notes require body modification when front top mounts are used; have the installer confirm the work for the exact set.
- Confirm the 55 mm application
- Agree front-mount fitting work
- Plan tyres and alignment
Specify the hardware and setup support around the build.
Read the buying advice
AST RIV-V1903SD is the 5200 two-way example in the 8S application table. Agree springs, supplied mounting parts and reservoir access with the installer. Include the stated body work in the quote and confirm the kit for the actual roof style and any previous changes to the car.
- Confirm the delivered set
- Allow for mounting and access
- Agree springs and setup support
Independent rear suspension. Separate spring and damper.
On a standard Audi TT 8S Coupé, the rear spring and damper are mounted separately.
Component layout only. Mounts, dimensions and adjusters vary by kit.Audi’s original 8S rear drawing places the coil spring on the spring link, inboard of a separate damper. The arrangement is independent, with several links controlling each wheel. It is not the beam-axle layout used by an original FWD 8N.
A replacement kit sold as coilovers can retain the separate rear spring. AST’s Street and Street Performance configurations describe that layout; the Clubracing set has a different rear-coilover description. Confirm the actual kit, supports and fitting instructions before choosing between them. This drawing shows the factory component positions.
Understand height and spring preload
Inspect the suspension already on the car
Have the installer identify the original or replacement dampers, mounting parts and front strut diameter. Add the actual wheel and tyre measurements. A registration lookup helps identify the original car, but it cannot reveal every previous suspension conversion or spacer.
Agree the usable height, supporting repairs and clearance checks before installation. Allow separately for fitting, alignment, electronics and any specified body work. Confirm current supply timing before booking, then follow the instructions for the exact delivered set.
Wheels, tyres and brake clearance
Check width, offset, tyre dimensions and spacers against the intended working height. Include a brake conversion in the wheel-clearance check. An attractive arch gap does not establish clearance at the spring, damper or caliper.
Magnetic ride and cabin controls
Identify electronic damping before ordering. Conventional-kit notes warn that factory damper control is lost. Agree the vehicle-specific replacement plan; suppressing a warning does not recreate the original damping modes.
Rear layout and mounting parts
Compare the delivered configuration with the parts the installer expects to reuse. A separate rear spring and damper needs a different fitting check from a rear coilover conversion. Confirm supports, top mounts, droplinks and any specified body work.
Working height and alignment
Inspect worn bushes, joints, bearings and tyres before installation. Agree a usable height, verify clearances through steering and movement, then measure alignment. Keep a record of later changes so adjustments can be compared.
The current TT 8S range.
Compare the controls and hardware included in each range.
S-39 names the ordinary 2014–2023 TT FWD/AWD, with BR-RA and RM-MA options. S-68 separately names the 2016–2023 TT RS AWD. The listed nominal spring rates are 6.5/5.5 kg/mm for S-39 and 7/5 kg/mm for S-68. Confirm body, engine and factory damper requirements with the selected reference.
View BC Racing TT 8S kits
The current list includes 5100 Street, Street Performance and Clubracing, plus 5200 and 5300 motorsport references. Their rear arrangements, mounts and damping controls differ. The manufacturer table names 55 mm 8S applications and flags body work with front top mounts; confirm the exact supplied set and fitting instructions.
View AST TT 8S kits
M 532 007SD and M 532 008SD are the listed two-way and three-way references. Both name the 55 mm 8S family in the application table. Their manufacturer set descriptions also mention Golf models; that does not replace confirmation of the actual TT set, roof style, mounts and reservoir access.
View MOTON TT 8S kits
Pro-Street S -01 is the listed FWD reference and -02 covers specific quattro engine rows. Ordinary quattro has 20–50 mm front and 20–45 mm rear figures; the TTS row gives 10–40/10–35 mm, and the TT RS row 10–35 mm at both ends. Check current axle limits, 55 mm condition, factory lowering and electronic damping against the exact application.

Before you order.
Identify your car
Identify TT 8S/FV, engine, build date, Coupé or Roadster and FWD or quattro. Distinguish ordinary TT, TTS and TT RS.
Match the kit
Match the complete reference, front strut diameter and axle limits. Identify magnetic ride and agree what its replacement means for the car.
Check what’s included
Confirm supplied and reused mounts, rear spring arrangement, droplinks and any body work. Different rear configurations need their own fitting check.
Check your modifications
Record wheel width, offset, tyre size, spacers and brake changes. Check inner suspension and outer arch clearance through steering and movement.
Plan fitting
Plan supporting repairs, fitting, alignment and electronics work. Confirm current timing and the installer’s settling and recheck plan.
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 Audi TT 8S coilovers.
Check the details before choosing your kit.
Which TT generation does this guide cover?
The third-generation Audi TT 8S/FV family introduced in 2014, including Coupé, Roadster, TTS and TT RS application checks. Earlier 8N and 8J cars use different references. Match the complete model, engine and factory suspension before choosing a kit.
Are the factory TT 8S rear springs separate from the dampers?
Yes. Audi’s original rear drawing shows a coil spring on the spring link beside a separate damper. The rear is independent. A replacement kit can retain that arrangement, so compare the actual configuration rather than assuming every coilover kit moves the spring onto the rear damper.
Is BC S-39 the same application as S-68?
No. The manufacturer list names S-39 for the ordinary 2014–2023 TT FWD/AWD and S-68 for the 2016–2023 TT RS AWD. Their current spring specifications also differ. Use the exact model reference and confirm original damper and body requirements.
Will coilovers keep the magnetic-ride modes?
Do not assume so. A conventional kit replaces the electronically controlled dampers, and the listed Eibach notes warn that factory damper control is lost. Agree a vehicle-specific replacement solution. A warning canceller does not retain the original damping function.
Can I use the FWD Eibach kit on quattro?
The listed -01 reference explicitly excludes 4WD. The -02 reference has separate ordinary quattro, TTS and TT RS rows, with different lowering figures. Compare the exact engine, axle limits, roof style, front damper diameter and current certificate.
Why do the AST rear configurations differ?
The current Street and Street Performance descriptions retain a separate rear spring and damper, while Clubracing names a front-and-rear coilover arrangement. Have the supplied set, rear supports, mounts and fitting work confirmed for the actual car.
How low can I run with wider wheels?
The workable height depends on tyre size, wheel width, offset, spacers and suspension parts. Check inner and outer clearance through steering and suspension movement. A catalogue lowering range cannot confirm clearance for a modified wheel package.
Should I buy the most adjustable kit for road use?
Choose controls and mounting hardware you can use and get set up properly. A road car still needs adequate movement, sound supporting parts and alignment. Remote reservoirs and extra adjustments add fitting and setup considerations; price alone does not establish the right specification.
Let’s talk suspension.
Find your TT, then add its engine, roof style, drivetrain and original damper equipment. Include wheel dimensions and earlier changes so the exact kit and fitting work can be checked.
