I currently have the Recaro seats (powered; actually sits lower than manual Z/28 Recaros by about an inch), but I am having issues at the track. The belt openings are too low on the seat, so my shoulders are a bit compressed. The seat is also sitting way too high; I have the feeling of racing with an SUV seat. FYI, I am currently using the seats along with Schroth Rallye 3 ASM harness and a HANS device.

Is there any solution where I can have a harness bar at the track day, but easily remove it once I'm done? I hate the idea of effectively canceling the rear seats.

Regarding airbag, there are small simulators sold on ebay for $15 or less. You can also simply put 3K Ohm resistor on the circuit to fool it (so the error light would not light up, and the rest of the airbags would still work). You would also need to carry the OEM seat belt receptor and position sensor, if any, to the new seat. Position sensor would only need to be connected. It normally signals only if the seat is too close to the steering wheel, but your race seat set-up will probably never be too close anyway.
