From Tom:
Get 5 lbs of dry-ice. Break it up into pebbles and spread it across the tar crap. Let it sit for several minutes. Use rubber mallet or hammer to strike the underside of the trunk. 99% of the tar crap will flake off in large sheets. Use scraper, or thinner or both to remove as much of the rest as you desire. Awesome tips here – thanks guys. I’ll attack this on Sunday.
Tar crap on front firewall, I used a needle descaler to remove it. ~1 lbs.
Remove excess nuts and bolts. 50% aren't needed. ~5 lbs. I’ve been doing this as I work on things. I’ve got half the bumper hardware removed, and about 1/3 of the fender hardware removed. After Road America I went through and removed misc. factory grommets that used to have factory wiring running from them.
Remove unused exhaust hangers. 1/2 lbs. Done already.
Use webbing based tow hooks instead of the 1/4" steel plate type. ~2 lbs. Great idea, that’s the easiest on the list!
The instrument cluster weighs 2 pounds. Do you need it? Unfortunately, I do L
door insulation on doors and pinch weld can be removed. 1-2 lbs. Already gone.
trunk lid rubber seal weights 2 lbs.
How gutted are your doors? the trim that seals to the door glass has steel embedded in it. Each side weights 3/4 lbs. Great idea, they are half falling off already too.
Do you have the driver's triangle vent window removed? ~2 lbs. Already gone.

If you were to post pictures of the under hood, inside of trunk, inside of car we could be more helpful I'm sure. Okay! I’ll do this on Sunday!
Your never going to get a 1.6 to 2275 pounds as you start a race. Think in terms of your finish a race weight being legal. Yeah, sage advice. I’m keeping that in mind already, that was one of the first things everyone taught me trackside as I’m attending more events.
Check the rules for the bracket for the spare tire jack. – Okay, I’ll re-read before I get the saw out!
The top of the door is IIRC triple thickness metal and IIRC either one side or both sides combined weigh 9 pounds. 2306 pounds minus 9 pounds equals 2297 pounds. Can you elaborate on this, I’m not familiar with what you are talking about?
Excess crack sealant squeezed out of cracks, interior and inside trunk. PIA couple pounds.
Fender liners, couple pounds. Already gone.
Seat weight??? It’s a really old Aluminum seat, so it has the added bracing in order to stay current. I could probably get a newer lighter seat, but that’s off the table for now due to $$$
Picture of roll cage, may be some extra tubes with minimal value or maybe some tubes could be of a better design. Okay! I’ll do this on Sunday!
