LA Rider, I have the race seat; had an upholsterer shave off half an inch (he said he did more) and re-cover it. He charged less than 70 bucks. I liked it fine, but I realized there was plenty of foam height left. So I took off another half inch on my own. Removed the cover again, marked area to cut using a pencil, used a sharp knife and serrated blades to cut a grid pattern, cut out the grid squares, ended up with a very rough surface but at about the height I had marked, then sanded the hell out of the foam surface till it was smooth and even, just eyeballing it. Then used some spray adhesive on the foam, stretched and smoothed cover back on. The seat's new profile made this a bit tricky, and restapling was a pain. But the height is perfect for me now, the grip is excellent, you're much more "in" the bike, and there is still enough of that high-density foam for comfort -- way more comfortable than stock, even though height now roughly the same. Plus, it was a reasonably easy and fun little project for a weekend.
