What is QRT Technology?
Designed and developed in Italy by Sparco, QRT technology is destined to generate the world’s lightest fibreglass frames and to define the features of the sports seats of the future. With this technology Sparco sets new standards of seat performance, reducing the unit weight by 30% compared to previous seats – enabling unprecedented mechanical strength/weight ratios in fibreglass sports seats.
