My LS1 Trans Am Projector & HID Conversion Thread
As far as adjusting the cut-off shield, it is typically not necessary. However, each projector design reacts differently.
HID projectors have a wider bowl to spread the beam wider with a brighter area just under the cut-off compared to the rest of the beam. This better spreads the light and improves distance vision. Putting HID in a Halogen Projector often results in a more uniform narrower beam.

I haven't seen any. I'd be curious how they'd compare to some other HID projectors.
The Hella 90mm HID projectors are too expensive and the output isn't as good as far cheaper OEM options. I'd would recommend avoiding the Hella 90mm HID projectors and going with something else (ex: FX, FX-R, TL, RX330, Morimoto Mini H1, E46, and others).

Once I modify the cutoff shield I'll take new cutoff photos as well as ground shots.
I'd be curious to see if you can modify this uptick before I go ahead and install mine!

Looking at the photo now it's MUCH more sealed than I originally thought. I may have seen something different?! Hmmm... I may sell my 60mm Hella lows and run a set of these shortly. They are almost $200, but the output is basically the BEST low beam projector on the market today.
Need to take some measurements now but anyone wanna buy my Hella 60mm lows if that's the case? haha

I haven't see the TSX-R before. Where are they available? Do they have better output than the OEM TSX? The FX & FX-R have better output than the OEM TSX (but they are physically larger if I remember correctly).
The TSX (and probably TSX-R) is not sealed. Its just less "open" than the FX which is already less "open" than other projectors like the E46 (which is very "open").
However, they do look similar to TSX projectors:

(That retrofitted on 2001FireBird's car, but not sealed.)
Here are a couple threads where people installed TSX projectors in a 1998-2002 Firebird:

If the RX projector has similar dimensions, then those threads may be helpful.
The links are also posted in the Lighting FAQ.

VIP: If I change to another projector I will be sealing it. Some silicone and I'll be good to go. That was the reason I went with the Hella's as they are fully sealed. Also another reason I didn't try to get the FX-R's in there, not to mention size issues. I really like the idea of the of either the TSX or the RX/TSX-R lens projector. I e-mailed my buddy at TRS to see what he suggest. We'll see how this goes!
I think I may modify the cutoff first, since I have them already. Then, if I'm not happy with the output, I may just sell them and get some better projectors. Oh, and for those reading this - these projectors are SO MUCH better than the factory output. This is nothing to do with that, I'm just very **** about how nice the light output and cutoff need to be
