I had the sunroof on my 3G and also on my 2G. I don't know much about the corbeau brackets on the 2G but on my 3G they were very low. I could only imagine them being just as low on the 2G. Let us know, you should just throw them in and test it out.
Edit: You can see how low the CR1's are on the 3G vs the headroom, there was plenty of room.
I think the passenger side wasn't reclined because my Ex liked to sit straight up.
