For the roof, are you welding on a non-sunroof (e.g. RSA) metal roof, or bonding on a plastic roof of some sort?

My roof is stock, but I have completely removed the sunroof and bolted in a fiberglass panel from Getty. This should be lighter than an all-metal roof, but not as stiff or safe (I am adding a roof net now).

I don't think I would miss my ABS much - it only kicks in when I have completely blown the corner anyways, but it probably saves flat spotting tires in that case.

Do you still have power steering? If not, do you miss it on the track? I used to do a lot of AX, but not anymore, so I think I could lose it without much impact.

With a lighter car, you might be able down-size your brakes, saving even more weight?

Good luck in your quest for 2100#! I am very interested in the final numbers.
