The Rear Axle Carrier Panel (RACP) is a well-known weak point in all BMW E46 models. Thin sheet metal construction and high-stress forces during acceleration, braking, and cornering often result in cracks or structural failure of the carrier panel, risking the structural integrity of your chassis. To remedy this issue, many enthusiasts install bottom-side sheet metal reinforcement plates. While these kits are essential for preventing stress cracks around the rear subframe mounting points, they do not address the overall flexibility of the carrier panel under high-performance driving conditions.
Turner Motorsport’s Rear Subframe Reinforcement Brace is the ultimate solution for enthusiasts seeking to eliminate carrier panel flex and prevent further RACP damage. Designed for high-performance driving and track use, this brace adds essential structural rigidity to the rear end of your E46, enhancing both durability and driveability. This brace is constructed from heavy-duty steel tubing and finished with a durable blue powdercoat for corrosion resistance and a striking appearance. During design, Turner's engineers ensured this brace was compatible with their underside Rear Subframe/Chassis Reinforcement Kit (ES#3006359), making it the perfect addition to a comprehensive chassis strengthening strategy.
Don’t let RACP failure and chassis flex limit your E46's performance potential. Upgrade to the Turner Motorsport’s Rear Subframe Reinforcement Brace to fortify your chassis, enhance stability, and unlock superior handling for both road and track use.

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.
