Xbox, Xbox 360, and Wii gaming consoles. The sliding seat of the car seat is mounted on the bottom of the seat. You can slide the seat forward or backward freely like a real car seat. Thrustmaster TX racing wheel.www.ebay.com
I really don't get how 90kg of brake pedal pressure is at all realistic. What are you simulating a 1940s car with manual drum brakes on all corners down a 15% grade in the mountains with heavy fade? Maybe adding a trailer????
If the goal is to be at all realistic then shouldn't it be realistic?
OK, here is the first thing I found:Google F1 brake pressure.
That style of seat has the added benefit of no head bolsters. They could be useful on the track but for a sim seat, you want your hips locked in and your head free. The sample seat shown on the GT-1 Evo looks cool but it would suck if you wanted to make a sim where you could look around.A true F1 seat will of course be custom moulded and made out of lighter composites. The drivers are also leaned back way more for packaging/aero reasons. You can look at Nascar seating positions as aero does not matter to the driver so driver position is better optimized to the driving IMO. As you obviously do not need to be aero your position should be entirely driver focused.
Here is my old PE bucket coveted to an "office chair". First pick is the raw bucket (grey spots are from a rattle can of primer that exploded in the car in the sun when parked after doing some roll-cage work). What I want to point out here is the transition from seat bottom to back and how the drivers hips/ass will be locked into the pocket, no reason that your braking force should end up anywhere but here. Second shows how thin the foam padding is, with a very little extra from the cover's quilting. Last what it looks like with the cover. Hope that helps.

As for mounting, I used a chunk of 1/4" steel plate as the mounting bracket in the car while we were setting things up. It was there for a while and street and track time and ended up all bent (from various "G forces" not braking) before I made proper brackets. This seat is the better part of 30 years old BTW.

Also, as you have no lateral Gs the side bolstering is not very important so you really just want something with the similar transition from seat to back IMO. Side bolstering is a comfort choice in this application but in the end also adds some structural stiffness to the seat itself.
The PE buckets usually have four threaded inserts near each corner of the base and I think will be taller sitting (base to seat) than the gaming chair, so some metal fab work will be required. I know even compared to regular car seats if you mount the PE bucket up on the OEM tracks you gain a couple inches in height and have to drive with the sunroof open....
