There are limited cars have stock seats that can safely use a harness. I would bet your Sentra isn't one of them, so don't try it, please, even w/ a brace. What I would suggest is getting you some racing seats and just swap back and forth for the track and street. It's just a few bolts a an hour or so of time.
Also, don't think you can do this in stages, and don't expect to still use your back seat even with a 4pt roll bar, b/c you can't. The rear passengers will NOT be safe. The best way to do this type of upgrade is all at once.
