The QRT-C is an all-carbon fiber version of the QRT-R. The QRT-C is the lightest “large” size carbon fiber seat on the market. The QRT-C weighs 9.5lbs (shell only) and 12lbs (with padding and cover). It is constructed with “Pre-Preg” aerospace grade carbon fiber, also known as Dry Carbon. The QRT-C was specifically designed for a large driver and it fits up to a 36” waist driver comfortably. The QRT-C is unique because it was designed to fit a larger driver but has excellent fitment into smaller cockpits The QRT-C requires the special QRT Side mounts (#600QRT) which allows the seat to be racked back for a comfortable seating position. The QRT-C is FIA approved.;
