Seat Back Braces

Seat Back Braces extend the protection or your roll cage to the back of your seat. A correctly mounted seat back brace will takes out the flex and movement of aluminum race seats, allowing for a more secure driver and improved vehicle feedback.

Seat Base Mounts

Bottom mounting a seat can allow the driver to sit lower, which can be advantageous if you’re worried about your head being too high in the vehicle. Use these seat base adapters to easily mount your race seat to your factory floor plan withour modifications. There is not a better time saver than using a properly designed seat base mount adapter.

Side Mounts

Seat Side Mount Brackets to make seat install easy. Most seat side mount brackets have either one set of standard holes and one set of oblong holes, to make mounting of a race seat in the preferred 20°ish angle possible. If a seat side mount - made of either steel or aluminum - has a taller side, we usually mount that toward the front of the vehicle to allow our recline.

Seat Sliders

Seat Sliders from OMP, Sparco, Cobra & Recaro make adjusting your racing seat's position with precision for custom positioning easy. Simple to install and a required item in all enduro race cars.
