Don't blame you, I'm 6'2" and 250lbs myself. One of the more common gripes are the narrow Recaros, they are snug for me on my thighs but the back is perfect. It's something I can live with though as it's just too much fun driving this thing, shame you couldn't find one. I've had a couple people flag me down wanting to see the car as apparently they're that tough to find right now and apparently the Focus is as well.
I'm sure you'll enjoy it, especially with the mods already. I'm stuck being bone stock for now but it's not a bad thing at all with this car.
