Bes your crazy dude, lol. I had my car down to 2080 without cutting anything. Everything under the dash removed, no sound deadning, everything in the bay that doesnt need to be there gone, wiring harness stripped and removed all unnecessary wiring, no exhaust (thats a big one). Keep in mind 2080 was still with a stock trunk w/ spoiler, stock hood, 40 lb duralast battery, and a passenger seat.
I also dont have any bumper supports front or rear. I was also turbo so keep that in mind that i had a lot of extra weight from intercooler, piping, turbo, manifold, wastegate and so on.
Im actually going to be putting carpet and the door panels back in to make sure it qualifies for the true street events. I figure with the full 10pt chromoly cage the cars final weight with me in it should be right around 2400 lbs which is perfect.
