I think Bluebimma bought a set of cheap aftermarket seats from autozone or somewhere, but i don't think he used them. Also, HuGo has a set of aftermarket seats in his ti. Neither had the "tilt feature though, but they both reclined. Every once in a while you'll see a used set of Sparco, Recarro or Cobeau on ebay, but I'm a little hesitant to buy seats on ebay. Try craigslist. As for tilting forward, I can't honestly say I've seen a set of aftermarket seats that tilt forward like factory seats. In fact, BMWs are one of the few vehicles that actually do this. Some aftermarket seats recline forward pretty far to allow rear seat entry, you might have to settle for the reclining/sliding method.
Edit, I just found these and they claim to have the tilt feature. Great price, but not exactly cheap:

There's so many knockoffs on ebay, I'd steer way clear unless you're positive they're authentic. Some/most of the knockoffs look real! I've always wanted to upgrade to aftermarket seats, my vaders just seem really heavy. But after shopping around a little, I'm pretty scared to pull the trigger because of all the immitations on the market.
