I use a single core aluminum radiator. Alum is lighter than brass. Also the single core reduces the amount of water in the system. My system holds just over 2 gallons. Small fuel cell. 3 gallon cell and only haul a couple of gallons of fuel in the car. A gallon of fuel is about 7 lbs. water is about 8 lbs per gallon.

No issues with the lithium battery. You do have to take care of it charge wise. It charges quick usually about 20 minutes after the run. I have a Go Lithium brand battery and charger. Check with them as they run specials every so often the battery is about $600 plus the charger. I have been using it for about 5 years. I only run one of them and have not had any issues with power in the late rounds. I carry a pony battery in the trailer to run the water pump and fan to cool the car after the run while the lithium battery is charging.

Seats,front and rear ,wiring harness, sound deadener , factory carpets ,all the unnecessary underdash stuff ,} defroster ducts and dash controls must stay }are the biggest gain for the least expense.
Door guard beams are also good for quite a bit of weight .
Aluminum bolts and screws on non suspension parts can reduce as much as 15 - 20 # on big cars. using the shortest bolts possible elsewhere all adds up.
Getting rid of the factory fuel tank in favor of a 3 gallon cell and pump is a big weight loss, but will take several hundred bucks from the budget. .
On the more pricy side are the lithium batteries ,but the weight savings are huge and when getting to the last 30-40 # is necessary an expense that may need to be taken.
I've had very good results using batteries from Antigravity Battery .
You mentioned adjustable seats , unless drastically different size drivers are going to be running the car, a waste of both money and weight .
Some modern steering wheels are are very heavy to dampen vibration, and to frevent breakage during airbag deployment .
Ive found light wheels that weigh as little as 1 3/4 pounds [Stock car stuff]

Remove all sound deadener, look in doors, 1/4 panels, and top. Remove stick out on bolts, big ones first. Lighter steering wheel, new glass is thinner sometimes. Put the correct gage wire for each load, remember bigger is heaver. Remove all unnecessary wire. Look in the rule book.
