The Circuit and slightly larger Circuit II competition seats are built using Sparco's QRT (Quick Resin Technology) process which has helped to reduce the weight by 3.85kg over previous Circuit models. Head protection is integrated for increased safety in lateral impacts.

• QRT manufacturing process for a much lighter seat with no compromise on safety or rigidity
• Offers a 30% weight saving over the superseded model whilst retaining rigidity and strength
• Integrated head protection for vastly improved safety in side impacts
• Non slip material in strategic areas to reduce body movement
• Self extinguishing fabric
• Side Fixing
• FIA 8855-1999 Approved

What is QRT?

QRT (Quick Resin Technology) is a state of the art manufacturing process developed by Sparco to create the lightest and most resilient fibreglass shell seats currently available. The QRT range of seats offer a 30% reduction in weight, compared to a fibreglass seat manufactured using traditional methods, without compromise to safety or quality.

QRT manufacturing process allows a seat to be of similar weight to a carbon fibre seat but at fibreglass cost. Non slip fabric is used on the base cushion and on the shoulders to increase body retention and a low profile, single piece cushion provides increased safety by keeping the legs inside the seat shell.
