Sparco ULTRA QRT Racing Seat  Ultra-lightweight racing seat performance without the premium price of carbon fiber. The Sparco ULTRA Racing Seat combines advanced fiberglass composite construction, a minimalist design, and exceptionally low weight to deliver a competition-ready seat for serious motorsport enthusiasts. Weighing just 11.4 lbs (5.2 kg), the Sparco ULTRA is one of the lightest fiberglass competition seats in the Sparco lineup. Its innovative QRT Ultra-Light Technology and exposed composite shell eliminate traditional fabric upholstery and padding, helping reduce weight while improving the driver's connection to the vehicle. Designed specifically for narrow cockpits, the ULTRA provides an exceptionally compact exterior profile while accommodating standard- to larger-build drivers. Its sculpted monocoque shell delivers ergonomic lumbar support, natural recline, and a low seating position without unnecessary bulk. With FIA 8855-1999 homologation, the Sparco ULTRA delivers professional motorsport construction for drivers looking to reduce vehicle weight, optimize cockpit space, and improve their racing position. Sparco ULTRA Racing Seat Key Features FIA 8855-1999 Approved: Homologated fixed-back competition racing seat. Ultra-Lightweight Design: Weighs approximately 11.4 lbs (5.2 kg). Advanced Fiberglass Construction: Lightweight composite shell engineered for exceptional strength and rigidity. QRT Ultra-Light Technology: Sparco composite manufacturing technology designed to minimize weight without sacrificing performance. Unpadded Racing Shell: Eliminates traditional upholstery and foam cushioning for maximum weight reduction. Low Seating Position: Minimalist shell design allows drivers to sit closer to the vehicle floor when appropriately mounted. Narrow Cockpit Compatibility: Compact exterior dimensions accommodate space-constrained race car interiors. Integrated Lumbar Contouring: Ergonomic shell shape provides natural back and lumbar support. Direct Chassis Feedback: Rigid construction helps drivers feel vehicle movement more directly. Integrated Harness Openings: Designed to accommodate compatible multi-point racing harnesses. Side-Mount Configuration: Compatible with appropriate competition seat mounting brackets. Exposed Composite Finish: Purpose-built racing appearance without conventional upholstery. What Is Sparco QRT Ultra-Light Technology? QRT stands for Quick Resin Tech, Sparco's advanced composite manufacturing technology developed to reduce racing seat weight while maintaining excellent structural performance. Developed in Sparco's OEM Composite Laboratory in Italy, QRT technology utilizes advanced fiberglass manufacturing processes inspired by aerospace composite construction. This technology allows Sparco to manufacture fiberglass racing seat shells with substantially less weight than many conventional fiberglass designs, approaching the performance characteristics of more expensive carbon fiber alternatives. The Sparco ULTRA takes this weight-saving philosophy even further by eliminating traditional seat upholstery and padding. The result is an exceptionally lightweight racing seat that delivers an outstanding balance of affordability, structural rigidity, and professional motorsport performance. 11.4-Pound Ultra-Lightweight Racing Seat Weight reduction is one of the most effective ways to improve overall race car performance. Reducing unnecessary vehicle mass can benefit acceleration, braking, handling, and responsiveness. At approximately 11.4 lbs, the Sparco ULTRA provides significant weight-saving potential compared with heavier upholstered competition seats. Its fiberglass composite monocoque construction eliminates unnecessary material while preserving a rigid and supportive shell. For drivers building lightweight track cars, time attack vehicles, or dedicated competition machines, the ULTRA provides a practical alternative to more expensive carbon fiber seats. Minimalist Shell Design for Maximum Driver Feedback The Sparco ULTRA Racing Seat is engineered to be used without conventional fabric upholstery or foam padding. By removing these components, Sparco reduces overall weight and creates a more direct physical connection between the driver and the vehicle. The rigid fiberglass shell allows drivers to experience vehicle movement and lateral loading with less cushioning between their body and the seat structure. Its contoured seating surface provides natural support through an ergonomically designed backrest, lumbar section, and lower seat profile. This unique approach combines lightweight construction with a focused, competition-oriented driving experience. Low Seating Position for Better Cockpit Fitment The Sparco ULTRA's minimalist construction can help drivers achieve a lower seating position compared with traditional padded racing seats, depending on the vehicle and mounting arrangement. A lower seating position can offer several advantages in dedicated competition vehicles. Additional helmet clearance beneath roll cages and roof structures Improved driver positioning in low-roof vehicles More flexibility when positioning the steering wheel and pedals Reduced seating height for drivers with longer torsos Potential for a lower driver center of gravity The actual installed height depends on the seat brackets, mounting points, floor configuration, and driver requirements. Designed for Narrow Racing Cockpits The Sparco ULTRA is particularly well suited to race cars with limited interior space. Its compact fiberglass shell helps accommodate vehicles equipped with roll cages, door bars, center tunnels, and specialized racing equipment. Despite its narrow exterior design, the ULTRA offers an ergonomically contoured seating area intended to accommodate a range of driver builds. This makes it an appealing option for compact sports cars, track-focused builds, and custom racing applications where conventional competition seats may create clearance problems. FIA 8855-1999 Racing Seat Homologation The Sparco ULTRA carries FIA 8855-1999 homologation, making it suitable for motorsport applications that accept this competition seat standard. Its fixed-back fiberglass construction is designed for the structural and safety requirements of competitive motorsport. Always verify the seat's homologation label, expiration date, installation requirements, and eligibility under your racing organization's current regulations.
