034Motorsport’s RS+ Adjustable MQB Solid Rear Sway Bar for Audi 8V A3/S3, F3 Q3, 8S TT/TTS Quattro, and Volkswagen MK7/7.5 Golf R, Sportwagen, and Alltrack is now available! The 034Motorsport Adjustable Solid Rear Sway Bar is made from a single piece of high-quality, solid 0.938” thick spring steel for maximum rigidity, and is designed to combat understeer while reducing body roll under hard cornering without negatively impacting comfort. Why choose the RS+ Rear Sway Bar over our Standard MQB AWD Rear Sway Bar? Our Standard MQB AWD Rear Sway Bar was designed to provide a neutral handling experience. It reduces understeer while allowing drivers to coax their car into oversteer as desired. The RS+ Rear Sway Bar ticks things up a notch, providing over 171% stiffer than the factory rear sway bar and an additional 70% stiffness over our Standard MQB AWD Rear Sway Bar. This additional stiffness is great for owners looking to maximize rear end rigidity, turn-in response, and better rotation—further reducing understeer and maximizing handling performance!

The 034Motorsport RS+ Adjustable MQB Rear Sway Bar can be used with or without an upgraded Front Sway Bar. For avid track enthusiasts or those looking for the sharpest cornering, our Front Sway Bar is recommended to be paired with our RS+ Rear Sway Bar upgrade. For those looking for the absolute most rear end rotation, the factory front sway bar should be retained. 034Motorsport Sway Bar Kits feature maintenance-free polyurethane bushings with a Teflon and polyester liner designed to enhance sway bar response speed while minimizing noise, vibration, and harshness (NVH). This liner also results in an extended service life that allows these bushings to even outlast your vehicle. With no need for additional lubrication, these bushings offer reliable, long-lasting performance without the hassle of regular maintenance and greasing. Built to withstand extreme conditions, the bushings are hydrophobic, heat-resistant up to 500°F, and resistant to water and common automotive chemicals. These bushings are covered by a limited lifetime warranty which covers material cracking, separation of the Teflon liner and polyurethane bushing, or squeaking under normal street or track conditions.

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.
