This is a general list for everyone, not
just your app. You already have some of this, and the 'vert
top helps some:

Aluminum water pump, intake. Headers vs exhaust manifolds.

Get rid of things like power antannea and go to a fixed
mount.
If you have glass roof panels, get them swapped for
the acrylic units (both of my panels togeather weigh less than
one glass panel).

How drastic do you want to get? How about things like A/C,
heat, speakers and radio?

I don't know what parts you would consider as
being practical to change out but . . . Like 'em or leave 'em,
here are a few suggestions.

Aluminum driveshaft and halfshafts.
80-82 door glass and
windshields are supposed to be lighter.
80-82 DANA 44 gear
housings are lighter.
Use the lightest weight aftermarket
rims vs. good looking ones that are heavy.
Radio
delete.
determine if any of the bumper supports / crash
protection components can be removed or fabricated from
lighter materials.

Ganey, how much does the heater weigh?

Flynhi, another great post you have going. You may want to
take into effect where you are removing the weight. Its
obviously more beneficial to remove weight that sits higher up
(like heads, acrylic top) as opposed to weight that keeps the
center of gravity low like driveshaft, etc.

I too am trying to remove a ton of weight off my car. I
think I've taken the horsepower as much as I like so now I'll
focus on removing weight. I plan on changing out seats,
changing to an astro top, removed spare, have fiberglass rear
spring, no rear sway bar, no A/C, aluminum heads and intake.

I can't imagine that a filled aluminum radiator is barely
any lighter than a filled OEM radiator. My OEM one was pretty
darn light when empty.

The problem with losing weight is that your suspension
changes. I noticed that after swapping to aluminum heads my
front ride height was raised slightly.

Guess I'll need to cut front springs one of these days to
bring it back down.

ps: once again, good topic; hope it
continues..

Don't forget removing jack too. That sucker is
heavy!

As a related note. I was using my dad's jack that came with
his '91 Nissan 300Z and that sucker is LIGHT. It looks very
similar to my Vette jack but its made of aluminum. Looks
really cool and was featherlight. May be a good (relatively
cheap) upgrade for those who want to keep spare tire but still
lose some weight.

Great topic Flynhi! I think by swapping the
brake booster for hydra booster you might loose some weight.
I've been a busy boy fabricating aluminum parts. Here's few
examples:

This is the inner rear bumber. The original item was 32Kg
and this is only 6Kg (sorry, but I don't have a glue what that
would be in pounds) and it won't rust either!

This pic shows the use of aluminum on the engine, all
brackets, pulleys, water pump, heads, intake etc. Notice the
small late model style Power steering pump and the small A/C
compressor.

I removed all the orinal A/C stuff and replaced them with
Vintage Air's compact gen 2 system. The evaporator is hiding
under the stock dash and I filled the ugly heater hole on the
fire wall with custom made aluminum plate.

I don't know yet the total weight difference of the car, it
was 1640 Kg with half tank of gas and w/o driver. I have
pratically replaced everything since, so it'll be interesting
to see the difference when it's finished.

Groovyjay, that is one sweet pulley set. Is
that one of the serpentine setups that allow you to relax the
tensioner and replace the belt in about 30 seconds?

I remember trying to change the belt on my mother's '96
Caravan thinking it was going to be the biggest PITA in the
world (aside from spark plugs in that thing which I refuse to
touch) but barely took 5 minutes. Takes longer to do a belt
swap on a 'vette where all the belts are readily accessable.
Giving serious consideration to a serpentine
conversion.

For what you're going to spend on getting rid
of weight, it might be cheaper to add some horsepower. There's
usually two ways...at least....to get the job done. I would
invest in some ignition, intake and exhaust parts and then
take it from there. You'd be surprised how much hp you can
gain with some simple "add-ons".

In my quest to make a lighter car the 81
Daytona front end and TT hood was more than 150 LBS. It was a
noticable difference on how the car drove. The front end and a
paint job was $7000 so it's not a practical gain. My sparco
racing seat is 12.7 pounds.

I need to get it weighed so I can give you my final
figure

I forgot to add. When I pulled everything out
of the back to put the roll bars in. 1979 L-82 I pulled out
the rear speakers the pull forward security shade and i could
not believe how heavy the sound insulation stuff was. after
the bars I decided to not put in all the heavy carpet and
stock hard wheel well fiberboard and insulation. Instead i
went with fire proof aluminized thermo tech thin padding and
thin car type carpet.

Adding horsepower does nothing for braking or
handling. Getting rid of weight does.

More diet suggestions: lose power steering and power
brakes.

Also, I know that in C1 (or was it C2) Vettes, power
windows and locks inexplicably weighed less than their manual
counterparts. Does anyone know whether this is the case for
the C3?
