Audi TTS Mk3 Performance Parts & Tuning Mods

Top Brands For Audi TTS Mk3 Upgrades

The Audi TTS Mk3 is well supported by several top performance brands, offering everything from exhausts and intake kits to suspension and styling upgrades. Below you will find leading manufacturers known for high quality tuning parts and track-proven reliability.

Audi TTS Mk3 Exterior Styling Upgrades

For the Audi TTS Mk3, there is a great range of exterior styling mods to sharpen its look and make it stand out. From aggressive body kits, splitters and diffusers to subtle spoilers, custom grilles and trim upgrades, you can dial in a more unique, motorsport inspired appearance that suits your build.

Suspension & Handling Upgrades

The Audi TTS Mk3 is sharp out of the box, but there is still plenty of room to boost cornering grip and agility. A good starting point is quality tyres, proper performance rubber instantly improves turn in, traction and braking feel. Pair that with uprated brake pads, braided lines and better fluid and you get much more confidence on fast road and occasional track use without going straight to a big brake kit. From the factory the TTS Mk3 can push into gentle understeer when really leaned on, helped by its Haldex setup and fairly soft road friendly suspension. Coilovers or well matched lowering springs and uprated dampers reduce body roll, sharpen steering response and let you dial in a slightly more neutral balance. Add stiffer anti roll bars and fresh performance bushes and the chassis feels tighter, with better stability mid corner and on quick direction changes. If you want to go further, a front strut brace and proper alignment settings bring even more feedback through the wheel. We usually recommend working in stages, tyres and brake upgrades first, then suspension tuning, then bars and braces. Done right, these mods make the TTS Mk3 feel more planted, more playful and simply more fun every time you attack a B road or a trackday.

Audi TTS Mk3 Frequently Asked Questions

What are the best first performance mods for my Audi TTS Mk3?

For a TTS Mk3, the best starting upgrades are usually an ECU remap, a high quality panel filter or intake kit, and a cat back exhaust. Together, these mods let the 2.0 TFSI engine breathe more freely and make better use of boost, so you get sharper throttle response and noticeable gains in horsepower and torque.

If you want a more rounded setup, consider a set of lowering springs or coilovers and uprated brake pads at the same time. These chassis mods make the most of the extra power and give the car a more planted, motorsport inspired feel without ruining daily comfort.

How much power can I safely gain from tuning an Audi TTS Mk3?

On a stock turbo TTS Mk3, a sensible stage 1 remap alone can offer a healthy bump in performance, usually a noticeable increase in both horsepower and mid range torque. With a good intake, sports cat or high flow downpipe, and a freer flowing exhaust, a stage 2 setup can push things further while still being road friendly.

The key is to work within safe limits for fuel, turbo and cooling. Sticking to reputable ECU tuning and quality performance parts will keep the engine operating within realistic parameters, so you get strong, reliable gains rather than chasing headline numbers.

Will tuning and performance upgrades affect the reliability of my TTS Mk3?

Any increase in power means the engine, clutch and drivetrain work a bit harder, but with sensible tuning and proper maintenance the Audi TTS Mk3 copes very well. A conservative remap from a trusted tuner, combined with high quality oils and regular servicing, keeps reliability high for a fast road car.

If you go beyond basic mods, such as bigger turbo, track use or very aggressive maps, you should budget for supporting upgrades like a stronger clutch, better intercooler and more frequent checks. Treat the car with mechanical sympathy and the extra performance does not have to shorten its life.

Do I need any supporting mods for an ECU remap on the Audi TTS Mk3?

For a mild stage 1 remap on an otherwise standard TTS Mk3, you do not strictly need hardware upgrades, although a fresh service and good quality fuel are strongly recommended. Many owners choose to add an uprated intake and turbo inlet pipe to help the turbo spool more efficiently and keep intake temps down.

For stage 2 tuning, you really should pair the map with a sports cat or decat downpipe, performance exhaust, better intercooler and possibly uprated spark plugs. These supporting mods allow the ECU calibration to run more timing and boost safely, improving both power and consistency.

What suspension and handling upgrades work well on the TTS Mk3?

The Audi TTS Mk3 responds brilliantly to chassis tuning. A good set of lowering springs or height adjustable coilovers will tighten up body control, reduce roll and sharpen turn in, without making the ride unbearable if you pick the right kit. For cars with magnetic ride, make sure you choose suspension that is compatible with the factory system or be prepared to code it out.

Anti roll bars, uprated top mounts and performance alignment settings are also worthwhile. Combined with lighter alloys or track focused rims and decent tyres, this transforms grip and confidence, so the car makes much better use of any extra power from engine mods.

What wheel and tyre sizes fit well on an Audi TTS Mk3 for a tuned setup?

The TTS Mk3 comes with fairly aggressive factory wheels, but many owners move to 19 inch or lightweight 18 inch alloys for a better balance of looks and performance. Common fitments are around 8 to 8.5J wide with suitable offsets to clear the brakes and arches without rubbing on sensible ride heights.

For power upgrades and fast road use, a quality performance tyre is more important than just going wider. A properly chosen rim and tyre combo, along with correct alignment, gives better traction, shorter braking distances and more predictable handling, especially in wet UK conditions.

How much does it typically cost to tune and modify an Audi TTS Mk3?

Costs vary a lot depending on how far you want to go. As a rough guide, a stage 1 ECU remap for the TTS Mk3 sits in the lower hundreds, with an intake kit, cat back exhaust and lowering springs taking you into the mid to high hundreds in total for parts, plus fitting if you are not doing it yourself.

Moving to stage 2, with a high flow downpipe, uprated intercooler, clutch (if needed) and more serious suspension or brake upgrades, can take the total into the low thousands. Planning a clear upgrade path and doing the work in stages is usually the most cost effective way to build a quick, reliable and well balanced car.

Final Thoughts on the Audi TTS Mk3

The Audi TTS Mk3 is a cracking all rounder from the factory, quick enough to feel special yet refined enough to use every day. It has sharp styling, a punchy turbo engine and sure footed quattro grip, which makes it a brilliant base for thoughtful mods and upgrades. What it lacks slightly in drama and edge out of the box, it more than makes up for with tuning potential and solid underlying engineering. With sensible performance parts, like a higher flowing intake, exhaust and a quality remap, the TTS Mk3 responds very well, giving stronger mid range pull and a more engaging feel without turning it into something unruly. Supporting upgrades, such as an uprated intercooler, uprated DV and PCV solutions, and a decent clutch or DSG hardware where needed, help keep things reliable as torque goes up. We often see owners pairing these power mods with better brakes and tyres, since the stock setup can start to feel a bit out of its depth when you really lean on the car, especially on fast road or occasional track days. On the chassis side, the standard suspension is capable but a touch soft and conservative if you are chasing lap times or a very direct road feel. Quality coilovers or improved springs and dampers, matched with upgraded anti roll bars and fresh alignment settings, tighten everything up and reduce understeer, yet can still be kept comfortable enough for daily driving. Add in a set of lighter alloys, a more purposeful stance and a few subtle styling tweaks and you end up with a TTS Mk3 that looks as serious as it now drives. We have seen plenty of Audi TTS Mk3 builds where owners have carefully addressed these known weak spots, from heat soak and brake fade to drivetrain wear when torque is pushed too far without the right hardware. The result is not a completely different car, it is a better version of what the TTS already is, a fast, composed and confidence inspiring coupe that finally lives up to its potential. With the right combination of tuning, handling upgrades and tasteful cosmetic mods, your TTS Mk3 can be tailored to your own tastes, whether that is a discreet daily with extra punch or a focused weekend toy. It is a fantastic platform for enthusiasts, and with a bit of planning and the proper performance parts, you can build a TTS Mk3 that feels genuinely personal every time you get behind the wheel.
