Didn't see anybody mention an aluminum flywheel !!!!! You get a double payoff, reduced weight plus the acceleration efficiency of the lower rotating mass..... For onyl a meer $500 ????????? :steering:

The simplest way to save weight on a C3 is to drain ALL fluids....and
fill the entire car, all cavitites with.....
helium!!!!
or hydrogen...the ultimate fuel!!!

A 68 with a small block weighs in at 3,200 and a 75 with a small block weighs in at 3,700... but an 82 with its "standard optioned" block... weighs in at 3,200 again!
you sure they didnt change from net weight to SAE weight? :lol:
but seriously what is in the 75 thats not in the 68 that would add THAT much. Are all the body panels heavier. The frame, engine, differential, suspension parts, and tranny are all the same damn parts.

thats very upsetting since i own a 75. How the heck did they manage to add 500 pounds to the blasted thing? I know about the low speed bumpers and they're heavy, but 500 freeking pounds?

To list a few:
They changed the front bumpers
They changed the rear bumpers
They added side impact support bracing
Then... If you take into acount all the options and what not... You rack up a heavy weight car :cheers:
Luckily... The 75 that resides in the garage has been hit in the front... repaired poorly and all front bumper material removed... Not an NCRS top flight to say the least :crazy:

Re: Lightening a C3... Random thoughts. (ZD75blue)
When I eventualy come to the point where I'll be installing new lightweight buckets, I want to be selfish and ditch the heavy tracks in favor of some custom fabricated aluminum brackets. My seats won't be adjustable, but I don't see how that affects me driving it.
About the bumper. I may cut that out.
I wonder how harsh the ride would be with aluminum body mounts.
I also wonder how harsh it would be to ditch the engine mounts.
Is it possible to get lexan formed? (IE replacing the rear glass)
Are there any one piece front ends (bumper included) that don't have that integrated super low spoiler thing going on?

Re: Lightening a C3... Random thoughts. (applevette)
I have always thought it would be the coolest thing if someone could fab up rotors and calipers right on the spindle that goes into the differential. So you have less unsprung weight. I saw it done on some old race cars and thought it was awesome. I will do it some day when I have alot of money. :lol:

jaguars have that and indeed the unsprung weight reduction is nice but think about it, loosing a 1/2 shaft, u joint or anything after the stub/rotor and you have NO brakes on the rear wheels.

Just switching to the Steeroids rack and pinion will save maybe 10 pounds.
Gene will love this one. If you really want to save weight!
Find a manual steering (1982-198X?) Cavalier or Sunbird rack and pinion. Use the Steeroids mounting brackets, tie rods, tie rod adapter plate, and intermediate shaft. Now you will be up to about 15 pounds over the stock power steering system.
BTW, don't even think about using one of those manual steering Corvair aluminum or the cast iron Vega recirculating ball steering gears. They were only designed for those real light weight front ends.
The standard (non-adjustable) steering column is about as light as you want to get. Don't gut it. It is designed to telescope and absorb energy in a severe frontal collision. Just what a serious racer might need.
