The naturally aspirated 4.2L V8 in your Audi B6/B7 S4 delivers classic V8 power and Quattro traction, but the factory drivetrain leaves serious performance on the table. Tipping the scales at a hefty 26.5 lbs, the stock dual-mass flywheel dulls engine response, slows rev-matching, and masks the true capability of your high-revving 8-cylinder engine. Pair that with a factory clutch prone to slipping under tuned torque levels, and your drivetrain quickly becomes the bottleneck.
The ECS Tuning Stage 2 Performance Organic Clutch & Lightweight Flywheel Kit is the ultimate direct-replacement drivetrain overhaul for enthusiastic street drivers and track weekenders alike. By combining our high-clamp Stage 2 organic clutch with our precision-engineered 18.9 lb. lightweight single-mass flywheel, this kit sheds 7.6 lbs (a massive 29% rotational mass reduction) right off the crankshaft.
The result? Instantaneous throttle response, lightning-fast revs on downshifts, faster acceleration out of corners, and the torque capacity to handle up to 445 lb-ft of torque.
Engineered for Street Civility Performance upgrades shouldn't ruin your morning commute. Where many lightweight single-mass flywheels compromise daily drivability with aggressive noise, vibration, and harshness (NVH), our extensive testing confirms minimal to no increase in noise when installed. Coupled with a 240mm full-face high-performance organic disc, you get smooth, progressive modulation and chatter-free engagement with factory-like pedal effort.
Race-Grade Durability & Safety Each flywheel is precision-machined from heat-treated 4140 chromoly steel and hardened to HRC 28–32 for extreme strength, stress relief, and thermal stability under heavy load. Non-friction surfaces feature a black zinc coating for long-term corrosion resistance, and every unit undergoes dynamic balancing exceeding OEM G16 specifications (to 175 g-mm) for vibration-free operation all the way to redline.
For maximum peace of mind, the flywheel is SFI 1.1 certified—having successfully passed rigorous independent laboratory testing spun at 1.5x engine redline for one full hour without failure. An integrated tone ring featuring an OEM-matched gear tooth profile ensures seamless, flawless interaction with factory engine electronics and crankshaft position sensors.
Our B6/7 S4 Performance Clutch & Lightweight Flywheel Kit was designed, engineered, tested, and quality inspected by our Research & Development team at our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

Products are warrantied by their manufacturer. Eurosport Performance is an authorized reseller: every part we sell is covered by the manufacturer's own warranty, with its own terms and duration. Claims go through us, so you deal with Eurosport Performance rather than a form on the brand's site, but whether a claim is accepted is the manufacturer's decision.
Manufacturer terms apply Duration and coverage are set by the brand and differ from one to the next: some cover one year, some a lifetime, some only the original purchaser. The brand's warranty page is the reference; ask us if you cannot find it. | We file the claim for you Contact us with your order number, photos and a description of the issue. We open the claim with the manufacturer, follow it up, and arrange the repair, replacement or credit they approve. The manufacturer decides whether the claim is accepted. |
Fitment guarantee: North America only We guarantee fitment for vehicles sold in the North American market. Vehicles from other markets are out of scope; specifications differ, and it is the customer's responsibility to confirm compatibility before ordering. | No warranty on tuning files ECU and TCU tunes and other software files are sold without warranty and are not returnable once delivered or flashed. Tuning can affect your vehicle's factory warranty; please read the brand's terms before purchasing. |
Proof of purchase Your Eurosport Performance order is the proof of purchase every manufacturer asks for. Keep the order confirmation; it is also in your account on the site and in the SPECD app. | What is usually not covered Damage from improper installation, modification, abuse, racing or an incorrect application for the vehicle, and normal wear items such as pads, clutch discs and filters. Shipping and labour are covered only when the manufacturer's terms say so. |
It is the manufacturer's warranty for that product. Where the brand publishes it, we note it in the description; otherwise contact us before ordering and we will confirm the exact terms with them.
Stop using it if it is a safety-related part, then contact us with your order number, clear photos, and when and how the issue appeared. Do not return anything until we confirm the claim; manufacturers often require an inspection or an authorization number first.
The manufacturer. We prepare and submit the claim, provide the proof of purchase and push for a fair outcome, but acceptance, replacement or credit is their call under their terms. We pass their decision on to you as soon as we have it.
It depends on the manufacturer. Simple cases are approved in days; claims that need the part inspected can take a few weeks. We keep you updated at each step and push when it drags.
No. Tuning files are software; once delivered or flashed they cannot be returned, and they carry no warranty from Eurosport Performance or, in most cases, from the tuner. Support for the tune itself (revisions, flashing questions) comes from the tuning brand under its own terms.
No. Our fitment guarantee covers vehicles sold in the North American market only. European, Japanese and other market vehicles can differ in engines, electronics and dimensions, and a part listed for the North American model is not guaranteed to fit. If you order for one of these vehicles, confirming compatibility is your responsibility, and fitment issues on such vehicles are not covered by returns or warranty.
Labour is not covered unless the manufacturer's terms specifically include it. Having the part installed by a qualified shop protects your claim: improper installation is the most common reason a manufacturer declines.
No. Returns cover unused parts you no longer want, under our refund policy. Warranty covers a part that fails in use, under the manufacturer's terms. If you are unsure which applies, contact us and we will point you to the right one; please do not open a bank dispute, as it pauses both processes.
Questions about coverage before you buy? Email us with the product and your vehicle and we will confirm the manufacturer's terms.
