The seat tray is what you bolt your seat to. The Tray and seat will lock into any In&Out seat mount base. The tray is designed to be adjustable in width so if needed your seat can quickly lock into another car with the In&Out Seat Mount.
The tray locks into the base in four positions. The lowest position puts the bottom of the seat about 3/8" from the floor. Each position raises the seat 3/4" and moves forward 1 1/2".
You will only need one seat base per seating location. The seat bracket base receives any number of seat bracket trays as long as they are set to the same width. Your racing seats bolt to this tray. It is cable operated by the release handle. The seat tray is locked in with the spring loaded closed main slide lock. It is designed to remain locked in an accident or cable failure. The slide lock is held in place in an accident by 2 safety locks 90 and 180 degrees from the main lock.
The Seat tray will accept aftermarket reclining bottom mount seats from Sparco and Corbeau.
The design of the Docking Base may allow the factory seat to fit in its original location using the original bolt locations. To do this just leave out the Seat Cradle and bolt in the original seat. This won’t allow quick release of the original seat but all the factory safety devices will be intact.
The side mount brackets have 29 holes each. This allows each seat to have its height and recline custom to each driver. They also allow the seat to be adjusted side to side to align with the pedals and steering wheel. This position is locked to the tray and will stay with the seat when moved from car to car or side to side.
The seat is released by the remotely mounted handle. The handle can be mounted on a 1 3/4 roll bar or bolted to a flat panel.
The In&Out Seat Mount makes a great mounting point for other equipment. This will let you configure the car as you need in seconds. Or remove the equipment to gain access for interior maintenance.

At the beginning of the design we began to gather safety requirements from SFI and FIA. Then we did our homework in several club racing organizations and NHRA. We wanted to be sure that we designed and built a very safe product.
We found is that there is very little in requirements for seat brackets. Everywhere we looked the verbiage was something to the effect of “securely mounted”. In fact the only requirement that we could find was FIA appendix J article 253 states “the minimum thickness of mounting supports and counterplates is 3mm for steel and 5mm for light alloy materials”. There is a requirement for “quick release” systems to withstand a vertical and horizontal load of 18,000 N (4,046 lbs).
A good start, we wanted to know what we could find on mounting it in the car. Once again almost nothing to be found. FIA states contact surface area will be 40cm2 for each mounting point. FIA has a requirement for four mounting points using an 8mm grade 8.8 bolt.
We started with the material thickness. Our material is .1406 thick. Probasco Design did the CAD work and load tested using Solidworks CAD software. We used six 7/16 bolts per side to ensure we would meet the 40 cm surface area.
NOTE: The seat bracked does does not meet the SFI 2,875 lb requirement to retain seat belt mount.
