In this suspension tuning guide, we'll explain how to reduce understeer and unlock more cornering grip from the Audi TTS and TT RS (FV/8S). The following upgrades will also improve steering communication and enhance engagement.
The TTS and TT RS (FV/8S) are based on VAG's MQB platform. Powerful engine performance make them appealing sports cars, yet their handling on the road and track is underwhelming.
The great news is that bolt-on upgrades manufactured and supplied by Suspension Secrets cure these dynamic flaws. In this TTS and TT RS suspension tuning guide, we’ll explain how correcting front camber and uprating springs and dampers achieves superior cornering ability and boosts driving enjoyment.
TTS/TT RS Suspension & Handling Overview
Audi launched its Mk3 TT in 2014 and manufactured it until 2023. Towards the top of the range sat the TTS model with two-litre, four-cylinder turbocharged engine producing 320hp. The range-topping TT RS boasted a 2.5-litre five-pot turbo developing 400hp.
Both the TTS and TT RS are based on VAG's modular MQB platform. Up front are MacPherson struts, and at the rear is a multi-link setup. The TTS and TT RS also feature Quattro all-wheel-drive.
TT Suspension Limitations
When driving a TTS or TT RS hard on the road or track, their MQB chassis quickly displays several issues. Common complaints include:
- Front end understeer/push
- Steering low on feedback and weighing
- Underwhelming turn-in response
- Excessive front tyre wear on track
- Poor body control through transitions and during heavy braking
Without these problems, the TTS and TT RS would be epic driver's cars. There is significant untapped potential in these hot hatchbacks, and thanks to their powerful engines they become forces to be reckoned with following suspension upgrades...
Common Handling Problems (And How To Fix Them)
The Audi TTS and TT RS (FV/8S) suspension upgrades covered in this guide allow you to achieve the following...
1. Increase front camber and significantly reduce understeer
2. Improve the clarity and weight of steering communication
3. Enhance overall handling precision and consistency
4. Reduce the ride height and improve body control
Once these improvements have been made, the TTS and TT RS will feel far more stable, precise and responsive at higher speeds. They will also transmit grip levels to the driver with greater clarity, boosting overall confidence.
Suspension Geometry & Alignment Setup (Top Tip)
A full suspension geometry alignment is essential after installing new suspension parts. By correctly adjusting camber, toe, and caster (where available), alignment ensures you maximise grip, stability, and tyre life.
Benefits of a TT Geometry Setup
- Sharper steering response
- Increased cornering grip
- Improved rear traction
- Enhanced braking stability
A professional alignment is the single most cost-effective handling upgrade you can make.
Audi TTS/RS Suspension Upgrades
This section covers essential Audi TTS and TT RS suspension upgrades that will deliver a new level of handling performance on the road and track. These bolt-on parts are perfect if you are craving more engagement, response and feedback from your TT.
Adjustable Camber & Caster Plates
Why TT Camber Plates Matter
- Reduce understeer
- Sharpen turn-in
- Increase steering feedback
- Improve tyre wear on track
Suspension Secrets camber plates also increase caster angle, providing dynamic camber gain as steering lock is applied. As well as further improving turn-in response, caster also enhances steering feel and weighting. An added bonus is that Suspension Secrets camber plates are fully compatible with aftermarket coilovers that use the OEM top mounts.
KW V3 COILOVERS
Aftermarket coilovers are a superb upgrade for fast road and track-focused 8V S3 and RS3 models. We recommend systems from manufacturers such as KW, Moton and Öhlins.
The 2-way KW V3 Coilovers feature independent compression and rebound adjustment. These 2-way adjustable TTS/TT RS coilovers increase chassis response, reduce body roll, and improve overall balance for road and track driving.
2-way Coilovers Benefits:
- Independent bump and rebound tuning
- Improves handling, grip and body control
- Offers ride height adjustment
- Suitable for the road and track
KW V4 Clubsport Coilovers
For Audi TTS and TT RS owners searching for the ultimate coilover system for track driving, look no further than 3-way KW V4 Clubsport Coilovers.
KW V4 Clubsport coilovers for the TTS and TT RS feature low- and high-speed bump adjustment, plus rebound adjustment. Three-way adjustable coilovers allow you to control grip level, chassis balance, comfort level and stability - independently of each other. This is why they're used in professional motorsport.
How 3-way Coilovers Work
Rebound: How fast the suspension extends after compression
Low-speed compression: Affects handling balance
High-speed compression: Affects ride quality and grip over bumps
Aftermarket coilovers also allow you to adjust front and rear ride heights. Once professionally set up, coilovers help the tyres maintain more consistent contact with the road, improving handling performance.
Audi TTS & TT RS Suspension FAQs
Will suspension upgrades reduce understeer?
Yes. Increasing front camber with adjustable camber plates significantly improves front-end grip and reduces understeer during fast cornering.
Are camber plates enough on their own?
Camber plates deliver noticeable gains, but pairing them with quality coilovers further improves balance, body control and overall handling precision.
What do adjustable coilovers improve?
They enhance chassis response, reduce body roll, improve grip consistency and allow ride height and damping adjustment for road or track use.
Do I need a geometry alignment after fitting parts?
Absolutely. A professional alignment ensures camber, toe and caster are correctly set to maximise grip, stability and tyre life.
Will upgraded suspension affect ride comfort?
When correctly specified and set up, adjustable suspension can retain good road comfort while delivering much sharper handling.
Tested and developed by Suspension Secrets through extensive road and track evaluation, these upgrades unlock the full potential of the Audi TTS and TT RS (FV/8S).
