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 to fit 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 tray is the part that sets the width of the kit. It adjusts in 1/4” increments. You will adjust the kit as wide as possible then bolt down.
When at the narrowest setting it is 18 1/4 min. Widest is 23 1/4 to the outside of the Frankenstein bolts on the tray. This would be the wisest point on the kit but it is not at the lowest point when installed. The width needed on the floor of the car can be 18 min to 23 for the locking base in the floor of the car.
The length of locking base is 18 1/2" long. Note the tray will hang over the rear of the base by 3/4” in the lowest position. This is normally not a problem as the seat will hang over by a few inches also.
This depends on the width of the floor of the car. Subtract 3/4" from the narrowest part of the floor where you will bolt the kit down. This will give yo an idea of the width of seat you can install. The inner edge of the side mount brackets can adjust to 16 1/8 min to 21 1/8 max.
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. It states “the minimum thickness of mounting supports and counterplates is 3mm for steel and 5mm for light alloy materials”. InandOut Seat Mount is T304 stainless .1404 (3.5mm)
FIA requirement for “quick release” systems must withstand a vertical and horizontal load of 18,000 N (4,046 lbs). The InandOut Seat Mount was tested eight times and exceeds the FIA requirement by 300 pounds. If you're wondering that is 20 G for a 220 pound driver.
FIA states contact surface area will be 40cm2 for each mounting point (4 ea). FIA has a requirement for four mounting points using an 8mm grade 8.8 bolt. InandOut Seat Mount uses eight 7/16 bolts with large 1.5 washers to ensure we would meet the 40 cm surface area.
Probasco Design did the CAD work and load tested using Solidworks CAD software.
NOTE: The seat bracked does does not meet the SFI 2,875 lb requirement to retain seat belt mount. (yet) So seat belts must be mounted to the car.
