Audi TT Mk1 with Mirco RTS-2 Seats – A Track-Ready Build
When it comes to building a track car that’s equally eye-catching and capable, this Audi TT Mk1 customer build is a brilliant showcase of how the right interior upgrades can transform your on-track experience. Our customer has kitted out their TT with a pair of Mirco RTS-2 FIA fixed-back bucket seats, creating a motorsport-focused cockpit that delivers both support and style. Paired with OMP direct-fit subframes, Sparco sliding runners, and Endurance Motorsport multi-point side mounts, this install is rock-solid, secure, and fully race-ready.
With plans to head to Goodwood for upcoming track action, the owner wanted a seat setup that offered confidence-inspiring containment, breathability, and FIA compliance. Finished in 3D spacer fabric, the Mirco RTS-2 seats help keep the driver cool under pressure while delivering the kind of firm hold that fixed-back seats are known for. Whether it’s a hot lap or a full-day event, this Audi TT is now fully prepped to perform—and look the part doing it.
Mirco RTS-2 Bucket Seats – FIA-Approved Motorsport Performance
The Mirco RTS-2 is a premium, FIA-approved fixed-back fibreglass seat built for serious track and motorsport use. This seat is a favourite among performance-focused drivers due to its deep bolsters, wraparound design, and ultra-supportive padding that provides maximum driver stability under lateral G-forces.
Key Features:
- FIA 8855-1999 approved – ready for all motorsport disciplines
- Constructed with a rigid fibreglass shell
- High shoulder supports and deep leg bolsters for maximum security
- Trimmed in 3D spacer fabric for breathability and grip
- Built for tall drivers (34–38” waist) needing both support and space
This is the seat of choice for drivers who demand a professional feel and fit, with FIA certification that ensures it’s track-legal and purpose-built.
Mirco RTS-2 Seat Dimensions – A Perfect Fit for the Audi TT Mk1
Fitting full-size FIA bucket seats into the compact cockpit of an Audi TT Mk1 isn’t always straightforward—but the Mirco RTS-2 strikes a great balance between generous driver support and compact fitment.
Key Measurements:
- Shoulder Width (A): 590mm
- Hip Width (C): 430mm
- Overall Height (E): 920mm
These dimensions make the RTS-2 one of the largest FIA seats that will fit inside the TT Mk1 without modification. Wider seats may interfere with the centre tunnel or door cards, so we recommend using the RTS-2 as a benchmark—if your seat is wider than this, you’re likely to run into clearance issues.
Mirco RTS-2 In-Store – Available to View and Test
We understand that choosing the right bucket seat is a big decision, especially when it comes to finding the perfect balance between fitment, comfort, and support. That’s why we keep the Mirco RTS-2 bucket seat on full display in our showroom, available for customers to sit in, test, and compare in real-time. Whether you’re unsure about the bolstering, seat width, or the feel of the 3D spacer fabric, being able to try before you buy is one of the best ways to make the right choice for your build.
We stock the RTS-2 in both 3D spacer fabric and soft velour trim options, so you can assess the texture, breathability, and grip each version offers. You’ll also be able to compare it side-by-side with other FIA-approved bucket seats from Sparco, OMP, and Corbeau. Our team is always on hand to provide expert guidance on vehicle fitment, mounting compatibility, and the full range of installation hardware available. If you’re planning a visit, feel free to bring your own measurements or even helmet for a realistic fitting session—we’re here to help you get it right the first time.
Audi TT Mk1 Installation – OMP + Sparco + Endurance Motorsport
To install these seats properly, our customer used a well-matched combination of parts for compatibility, adjustability, and security:
- OMP Audi TT Direct-Fit Subframes: Designed specifically for the Audi TT Mk1, these subframes are motorsport-oriented and do not include OEM seatbelt mounting provisions, so we recommend pairing them with aftermarket harnesses for a complete setup.
- OMP 801 Black 4-Point Harnesses: To complete the track-spec setup, our customer installed a pair of OMP 4-point bolt-in harnesses. These harnesses are a perfect match for the OMP frames, offering secure restraint, improved safety, and full compatibility with the Mirco seat’s harness slots.
- Sparco Sliding Runner Kit: These sliders use a 345mm bolt pattern, making them fully compatible with Sparco, OMP, and most fixed-back bucket seats, including the Mirco RTS-2.
- Endurance Motorsport Multi-Point M8 Side Mount Brackets: These brackets offer extensive adjustment, allowing the seat to be tilted, lowered, or raised to suit the driver. Their wide base spacing also helps accommodate the broader RTS-2 shell without issue.
This setup creates a rigid, race-ready mount that ensures optimal driving position, safety, and compliance with FIA regulations.
