After spending a little time looking at the seats and the tracks, I realized that it was probably possible to move the seat back about an inch. So I started searching and found the post about mounting the BRZ seats (thanks for being the guinea pig) and decided to take the plunge. Started while the Missus was gone, she just shook her head after saying something about "taking apart a brand new car..."
I spent a few hours yesterday, drilling out the 8 rivets and grinding off two welds that hold the seat brackets to the tracks. These were then bolted back into place, an inch further forward. Makes all the difference for a tall driver like myself.
I used 10mm bolts and nylon lock nuts. I also installed a 1/4" spacer between the front mounts and seat track to give a little angle to the seat bottom.
The seat has to come back out to put a little paint on the areas that are now raw metal and I'll get some pics then. Might also replace the hex bolts with button-head versions.
Things to watch out for...

Things to watch out for...
- There isn't much room for the bolt heads. I had to grind about half the head off. I think button heads will clear and they'll be easier to get tight.
- The brackets aren't spaced equally. One side had 9.5" between the front and rear, the other was 9.375".
- The rivets are pretty hard, start with new drills. Use an 1/8-3/16" to drill a pilot hole, then drill out the rivet with a 3/8" bit.
- The metal chips get everywhere. Wrap the seat up with a sheet or something and be mindful to blow off the chips as you go. Don't want to scratch the leather or embed chips into the cloth
- The plastic covers on the rear of the seat rails go back on using the stock seats.
