Key Features:
The Ultra QRT seat combines innovative materials and thoughtful design to deliver performance and comfort in a lightweight package:
- Constructed with patented QRT ultralight fiberglass composite technology developed at Sparco’s OEM Composite Laboratory in Italy
- FIA 8859-1999 approved for safety and competition compliance
- Designed to be used without covers or padding, enabling a lower seating position and improved chassis feedback
- Ergonomically contoured shell with ideal recline angle and lumbar support for enhanced driver comfort
- Fits narrow cockpit spaces while accommodating medium to large drivers (up to 36” waist)
- Requires Sparco Aluminum Side Mounts (#600W or #600W90) for proper installation and lowest mounting position
- Weight reduction of up to 30% compared to traditional fiberglass seats, approaching carbon fiber seat weights at a more accessible price
Construction & Design:
The Ultra QRT seat’s shell is crafted using a state-of-the-art aerospace-inspired QRT process, which produces a fiberglass composite that is both incredibly strong and lightweight. This advanced manufacturing technique ensures the seat maintains structural integrity under racing conditions while minimizing weight to improve vehicle dynamics.
The seat’s fixed back design features a smooth, contoured shape that supports the driver’s body precisely, reducing fatigue during long sessions. Its minimalist approach—without covers or padding—allows for a more direct feel of the vehicle’s movements, enhancing driver awareness and control.
Installation & Fitment:
The Ultra QRT seat is designed to fit most vehicle models with narrow cockpit spaces, making it a flexible option for various racing and performance applications. Due to its unique shape, installation requires Sparco Aluminum Side Mounts (#600W or #600W90), which enable mounting the seat at the lowest possible position for optimal driver ergonomics.
No modifications to the seat shell are necessary, but the correct side mounts must be used to ensure proper fitment and safety compliance.
