Hundreds Of Products Ready Today. Dispatch/Collection Check Out Our customer's BMW E90 with Corbeau Reclining seats and TRS Harness Belts
Here at GSM Performance, we love seeing how our customers bring their builds to life—and this stunning BMW E90 project is a perfect example. Our customer has installed a pair of Corbeau RXI reclining sport seats along with vibrant yellow TRS 4-point road harness belts, creating a striking and purposeful interior setup. The yellow harnesses tie in perfectly with the matching yellow harness bar and interior accents, giving the whole cabin a unified, motorsport-inspired aesthetic. This setup doesn’t just look great—it also adds a noticeable level of driver support and road feedback.
While this build isn’t aimed at full motorsport competition, it’s exactly the kind of upgrade we recommend for enthusiasts who enjoy fast road driving and the occasional track day. The Corbeau RXI seats offer improved lateral support compared to standard seats, and the TRS harnesses help keep the driver securely planted through corners and heavy braking. Paired together, they elevate the driving experience in a way that’s both functional and stylish, showing that with the right components, you can blend motorsport aesthetics with daily usability. Whether you’re heading to a car show or hitting a favourite backroad, this E90 now delivers on all fronts.
Why Upgrade to TRS Road Harnesses?
When you’re looking for improved safety, support, and style over factory seat belts, road-legal harnesses from TRS are a brilliant solution. Standard three-point belts work well for daily driving, but when the pace picks up—whether that’s on a mountain road or during a track day—they simply don’t offer the same hold and security.
TRS harnesses wrap around your upper body and shoulders to reduce driver movement during hard braking and cornering, giving you better feedback and control behind the wheel. Our customer chose yellow 4-point belts, adding a bold visual statement that ties together the interior and exterior styling. Road belts like these provide a great balance between performance and convenience—they’re easy to clip in and out of, and they work perfectly with sports recliner seats.
Why Upgrade to TRS Road Harnesses?
Our customer used the TRS Clubman Road Legal 4-Point Harness, which is designed for non-competitive road and track day use. These belts use clip-in ends for easy installation and removal, and a push-button buckle that looks and functions much like a factory seat belt.
Key features include:
- ECE approved for road use
- Clip-in ends with eye bolts included
- Easy-to-use push-button buckle
- Available in multiple colours: black, red, blue, yellow, green, and more
- Designed for road-going sports seats without the complexity or cost of FIA belts
Our customer chose a 4-point configuration—ideal for use with sports recliners like the RXI. 5- and 6-point harnesses require special seat slots and crotch strap mounting, which aren’t compatible with recliners. This makes the 4-point setup the perfect match for comfort and control.

The Corbeau RRS – The Perfect RXI Replacement
Although the Corbeau RXI reclining sport seat has now been discontinued, we have the perfect alternative available—the Corbeau RRS. As part of Corbeau’s Sportline series, the RRS carries over the same core strengths that made the RXI so popular: a road-focused reclining design, supportive bolstering in key areas, and sleek styling that works in both modern and classic interiors. In fact, the RRS closely matches the RXI in terms of overall shape, shoulder support, leg bolsters, and harness guide placement, making it a great option for anyone looking to replicate the comfort and performance of the original RXI.
The Corbeau RRS is available in multiple trim materials and finishes, including leather, vinyl, and suede, and you can even customise features like stitching colour or seat heating to match your interior. We stock a variety of RRS models at GSM Performance, including the standard version on display in our showroom, as well as more premium variants with factory-fitted upgrades. Whether you’re building a fast-road daily driver or a weekend track toy, the RRS gives you the same feel and function as the RXI, with modern touches and even more customisation potential.

Why This Setup Works for the BMW E90
The BMW E90 is well-known for its generous cabin size, well-balanced chassis, and driver-focused layout, making it an excellent platform for performance upgrades. Our customer’s build took full advantage of this by pairing a set of Corbeau sports recliners with vibrant yellow TRS 4-point harnesses and a colour-matched yellow harness bar. The cohesive styling throughout the interior adds a distinctive touch while reinforcing the sporty character of the car. The E90’s spacious interior makes it easy to install upgrades like these without compromising practicality or comfort, ensuring it remains a capable daily driver with track-ready looks and feel.
While this setup doesn’t meet FIA standards for competitive motorsport, it’s absolutely perfect for drivers who want enhanced control, comfort, and style for fast-road use and occasional track days. The Corbeau recliners provide better lateral support and a more focused driving position, while the TRS road harnesses help keep the driver firmly in place through tight corners and spirited driving. This combination brings out the best of the E90’s dynamics without making daily use a chore—exactly what many performance-minded enthusiasts are looking for. It’s a smart, balanced upgrade for those who want performance and practicality in one package.
TRS FIA vs Road Belts – What’s the Difference?
At GSM Performance, we offer both road and FIA-approved TRS harness belts. Understanding the difference is key when selecting the right belt for your use case.
| Feature | Road Harnesses | FIA Harnesses |
| Buckle Type | Push-button (clip) | Aircraft-style twist |
| Approval | ECE road legal | FIA homologated |
| Use | Daily driving, track days | Competitive motorsport |
| Comfort | More padding and ease of use | Focused on compliance and safety standards |
| Price | Lower | Higher due to FIA testing and standards |
Road belts are ideal for drivers like our BMW E90 customer—those who enjoy spirited driving, show car builds, and weekend track days. They offer the visual and performance appeal of race harnesses but with the practicality of road compliance.
