PHEW, what a long day. Included two trips to the hardware store (various bolts/nuts/etc) and one to Home Depot (for DeWalt electric drill, tired of running out of battery power).

First pic is with seat out

Second and third pic is Sparco seat in driver, stock passenger.

Basically, i sit at a nice incline and about 1 inch higher. There is still a touch of headroom with the roof on (i am 5' 11"). While not pictured, have the roll bar done and the shoulder harnesses all mounted to it. All i need to do tomorrow is mount the passenger seat and bolt up the roll bar and i am done. Must admit, you really need to be a contortionist to get the seat in. It is better to leave ALL seat bolts loose during fitting.

IMPORTANT: attach the innermost seat bracket to the car first, then mount the seat (with door side bracket already on the seat, yet with screws loose). The "trick" is getting the innermost side seat screws tight and also the innermost rear bottom bolt tight to the frame. i customized a hex wrench to make the shorter part of the "L" very short. i have more pics and will write a full description after the first of the month.

As for feel, a brief drive with the lap belts and WOW, i will NEVER go back to those stock seats! More descriptions to come once i get everything mounted tomorrow.

Yes, they are the Sparco Roadster as i knew fitting would be tight and these were smallish, light, and would be easyish to get in and out of. As for other tricks... The Yoko A032R (H compound) tires are on back order, but when they come in the tire place is going to heat cycle them for me and send them my way. i predict about three weeks off for that.

Have i forgotten anything (and keep in mind i DO want to keep her street (USA) legal. As such, some compromises have been made.

Excuse my ignorance, what does "heat cycle" mean?
With some tires, it is best to have the first time they are "heated" (operated) in a controlled way as rubber fomulations have certain properties. Many race (R spec) tires like to be heat cycled evenly and this is not always best done on public roads. Therefore certain companies that sell tires have special machines that will heat cycle the tires.

The advantage is a nice melding of the plastics and it is said to improve the life and even wearing of the tire.

Hope that makes sense.
All done, too tired to write an article but here are a few pics. As for how it all feels... GREAT! For once i am enjoying driving and not being tossed about in the seat. This allows more of my efforts to be for driving.
