Dunno how long your torso is, but I'm 6'5" and 285lb with similar waist. I couldn't safely race in our
Kirkey 45 RR Containment without some mods. Basically, I have the torso for 6'7" and legs for 6'3".
The head containment "wings" were just too low, so if I got into it they pressed on my
shoulders like a vise, and there was no quick way for egress. So we cut the uprights
and extended them by about two inches to get me to fit. It still works fine for the "racecar
driver" sized team members. We also installed the seat on sliders with some incline so they
could see over the steering wheel. They also use a bit of padding in the seat so they don't
rattle around in it. I think ours is a 16".
On thing I noticed a few years ago...I had to race a car with a very narrow seat (for me) and
when I sat in it at the garage I couldn't see how I could possibly spend 1-2 hours driving in that seat.
What I discovered was that once I was suited and booted, and out on the track, I didn't even notice it.
Of course, YMMV, but if our current car had an 18.5" seat my teammates might as well be racing
on a bench seat.
