The Sparco Circuit QRT II is an ultra-lightweight fixed-back seat well suited for high-end sim racing applications. Built using aramid fiber–reinforced fiberglass and Sparco’s QRT II manufacturing technology, the shell offers excellent rigidity while keeping overall weight low, ideal for motion and non-motion simulator rigs.

The slim backrest provides strong lateral support, while the thin-profile bottom cushion keeps the driver seated low for a realistic driving position without sacrificing comfort during long sessions. Integrated head bolsters improve stability and immersion, helping keep the driver planted under aggressive steering and braking inputs.

The seat is upholstered in durable, impact-absorbing fabric, with anti-wear material applied to high-contact edges for long-term use in sim environments.

QRT Technology

Sparco’s QRT II technology delivers an excellent strength-to-weight ratio, reducing weight by approximately 30% compared to traditional fiberglass shells. This results in a stiff, responsive seat that approaches carbon fiber weight while maintaining the durability and value of fiberglass.
