what steps can be taken to remove excess weight. I really want to improve my 1/4times. is it possible to skim maybe 200 pounds of the stock Z?

 

Of course, spare tire, jack and tools. Floor mats, trunk mats, maybe swap seats with some light weight seats.

The easiest way to drop weight is go on a diet. If I were to lose 40 lbs, I'd surely post better times.

Go to the track just above empty, maybe 3 gallons instead of full, this will shave 100 lbs

I'd say we have already shaven 200!!!

 

I bought TE37s w/ Toyo T1S. Even though I have much wider rubber, I shaved 40 lbs. off. I stayed with 18" and went with 8.5- 245/40 front 9.5- 275/40 rear. Underdrive pulleys could save a few lbs. of rotational mass.

 

Besides what has already been posted, remove the passenger seat, I bet it weighs a good 45+ lbs. Not much else you can do unless you want to start pulling off interior panels.

 

So far the best I can come up with is a Ti exhaust. Thats just about 60 lbs saved. Take out spare tire, jack, mat, tools on top of that and you've probably lost 100 lbs without sacraficing too much.

 

Light weight battery, SS brakes lines, different exhaust, lighter flywheel , pulleys, tires and wheels....etc, etc,etc
