I've done it on numerous occasions. Instead of taking the two seats apart, simply take them out as one unit, it can be kind of hard to remove any of the bolts without going through the trunk so I suggest cleaning it out, and getting to work. The noise, if you've gone I/E so far will be almost unbearable inside, but it's well worth it. The is a significant notice in the weight loss, or atleast that's what my ass is telling me. It can sound a bit rickety though, since I didn't feel like removing the seat belts and all. I just zip tied them all secure like and left the locks on the bolted in to the sheet metal. all in all I think it's about 6 - 10 total bolts that need to be removed. I also suggest getting a buddy to help carry out the 60/40 seat b/c I nearly scuffed my car trying to pull them out, they tend to fall all awkwardly if you're on your own. Just be careful and remember where each bolt goes. I put the bolts back in their respective places as to not lose them or forget which goes where.
