The Bravo Composite Seat is Built for Off-Road with added comfort and features. The biggest difference to this seat is the lower side bolsters that taper off towards the front. These hold you in snug when while bouncing around, but make it easier to get in and out of the vehicle. The Bravo is built with off-road in mind, with thick dual-density foam all around for added comfort, and large harness slots that allow a fresh air hose to fit through. The seat features built in lumbar support for long trips or endurance races. A wider hip area fits Drivers with up to size 42? waist comfortably. FIA 8855-1999 approved for racing.
