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
Built in head protection for vastly improved safety in side impacts
Non slip material in strategic areas reduce body movement for better comfort and safety
Available in standard size (Circuit) and large size (Circuit II) to accommodate a wider range of drivers
This latest version of the Circuit and Circuit II offer a 30% weight saving over the previous model whilst still remaining rigid and strong. This is due to the revolutionary QRT manufacturing process which allows a seat to be at carbon fiber weight but at fiber glass money. 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.

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 fiber glass shell seats currently available.
The QRT range of seats offer a 30% reduction in weight, compared to a fiber glass seat manufactured using traditional methods, with no compromise to safety or quality.
