Does anyone have either Bride Zeta 3 L or XLor Sparco Evo 2 or 3 Race Seats? If so, please contact me, I'd like to try them for fit, please. TIA -Doc

Brett doesn't have seats to sit in.

Yeah, I gotta sit in it. My shoulders are wide and most regular seats push my arms too far forward. I need a wider shoulder area. I tried a Profi XL. Fit my body perfectly, but won't fit in the car.

I've sat in a Zeta III before, and the Zeta III L probably won't be big enough. The normal Zeta III is tight if you're over 130-140lbs, and the L version isn't a whole lot bigger. It's only about an inch or so wider in the shoulder section.
