Yes, my seats are the factory base ones, ...and it is a coupe. I liked the separate headrest but wanted the look and touch of leather. One of the reasons I bought a base was because I did not care for the painted windshield frame/door handles etc and liked the base seats better too. Plus, with the money I saved, i figured I could use that to customize it. It is not a daily driver (have had it for 8 months, have 700 miles).
As far as the bars go, I know it is a coupe, and the bars really mean nothing safety wise, but I like the look and that's all that matters to me. I bought mandrel bent u-bend- mild steel 1 7/8" with a radius of 6". Cut them to fit and made aluminum mounting brackets (my brother owns a sheet metal shop) that mount from inside the tube for a clean mount. Then painted them to match the interior. No real protection, but everyone who has seen them thinks they look great.
