Correct, Take it with a grain of salt though I have no door cards. I know this is the racing section but for those who have interior still I have not confirmed that they fit with door panels.

The information here is great. I'm sure all the seats come in different sizes. Would like to know which sizes will fit inside the car with all the interior intact or without it. Again thanks for this information.

Will try my best! one of our employees has a stock S2000 but with it being winter here in Chicago it is put up until spring. I'll convince him to let us borrow it for these tests from time to time.

Thank you for doing this Devin. Theres no place around here that I can find that has actual race seats for me to try and Im in need of one. I identify more with your size and that Racetech sounds like it fits my bill.

If you fit in Racetechs I Honestly recommend them to everyone. Great seat, I wish you were local the one in our show room is also heavily discounted. So low I cant even post it.

Racetechs are great if you have a few Gs to spend. I really like the OMP seat size chart and the options that they provide. I can tell you that to fit an OMP HTE-R XL in my car I had to modify the transmission tunnel and my fiberglass OEM replica hard top to fit it.

well Racetech has dropped there prices some across the board. Rt1000 is now 690 new instead of almost 800.

As a point of reference, the HTE-R 400 has a narrower outside profile for the Halo wings and does not interference at all with the top, door, or window. I opted to trim my set (instead of modify the trans tunnel) to fit the seat.

When measuring shoulder height, please note if it is with HANS or without.

I'll probably never modify my car with seats or roll bar / cage, but who knows? I'm always "shopping" (pesky wife) for a second one.

Cool project, and I always have problems fitting seats (and helmets for that matter).

There is one important measurement you've missed. Hip width. All the manufactures think about that when designing a seat. (It's something women have to think about for anything manufactured for them, clothing, seats, anything.)

It's a fallacy to think that hip width is proportional to weight, for guys, it's got minimal correlation. Yet it is the most imporntat measurement if you are trying to do this objectively because it's gonna tell you if you're butt is gonna fit.

Measure horizontally around the widest part of the hips, or if the hips are essential straight vertically, then measure horizontally around the hips where the butt is widest/biggest.

For the seat, easiest way to learn where to measure is to simply have a couple of guys sit in the seats with their squivis on, and look where those measurements you just took correlate to where those areas of the hips and butt touch the seat and just use that as your measurement line. Measure all the areas of the butt, around the side of the hip and up to next to the hip to a point you'll have to standardize where it is above where anybody hips would not rise anymore. Don't measure just till the end of the edge of the seat as that will be different from one seat to another, yet have no bearing on what you are trying to measure (butt/hip size).

Again, a crucial measurement.

Thanks for letting me input, and please contact me if you have any questions.
