We are talking about where the pedals go. There's only two screw mounts for the pedal so there's a little flux at the bottom between the plate and the pad, instead of strap you can try to use the velcro that is provided with the playseat...
And when you install that conical brake Mod on your 3pa pedals, the entire metal Flexes a little bit when you press hard on the brakes. I ended up cutting some wood and building a mini frame underneath to support the back so it wouldn't be that much flex, but it's not that bad. I played the demo for 3 days in a row or maybe it was four and it said I did over 20 hours, the seat felt great to me. And I'm six foot three :-)
