C4 Weight reduction master list?
I've found quite a few threads on weight reduction, but nothing that would be called the "master list" and shows down to the bolt of what misc. stuff can be stripped. Does anyone have an entire list of everything to get an early model C4 under 3000 lbs and still be a street car (comfort in mind)? I thought I came across something like this a few months ago.... but i can find it. Thx.
Also, little off topic but I found a place that can build a completely forged 383 shortblock (using Eagle,SRP/JE) for $2399 and provide a year warranty on the parts and worksmanship. I priced all of the parts and work on the block and it would cost MORE to build the damn thing myself! Oh the power of buying in bulk.
Anyone interrested pm me.

I'd LOVE to see a sticky on weight reduction. There have been some good threads in the past, but the search function doesn't consistently work...so you can't get at it when you need it.
If you can't get a sticky going, a Tech doc would be a good fallback point...or maybe one of the guys with websites could host a page. I would even be willing to setup a site and host it, if need be.
I can tell you that on a '95...
a. Replacing Exhaust manifolds & stock cats with Hooker 2151's drops 40lbs...scale-confirmed.
b. Replacing spare tire (leaving carrier on), jack, and lugnut wrench with Fix-a-flat provides a 33lb reduction...again scale-confirmed.
I have the A/C Delete bracket from More Performance, Inc. sitting in the garage, but haven't had the time to install yet. If you get a doc going, I will post my results when I get around to it. (Another CF Member recently reported a 38lb reduction by removing all A/C components and using this bracket.)
I plan to go to a Fidanza aluminum flywheel sometime over the winter, and will post those results as well.
Good luck getting a Master List going!

Also, a nice tripple+ clear coat paint job will cause you to pick a CONSIDERABLE amout of weight.

You can take the bumpers off front and reaf and eliminate the honeycomb energy absorber for a great weight savings of around 100 pounds. Just don't hit anything or be hit by anybody. I found this out when I installed my Shinoda Body kit and the instructions had me drilling the rivots out to remove this heavy grey honeycomb. There is also the obvious floor mats. The rear pull shade and rear storage compartments. The stereo is also very heavy, esp if you have the bose system with amps in the speakers. Replace it with light weight unit and speakers. Any body mods or spoilers, only add weight. I picked up one tenth in qusrter by leaving spare tire and carrier at home. Dont get a flat. have a cell phone of a roll back handy. Go to light weight skinny front tires for the track. Thats what I have done so far... Good luck

Removing the honey comb sounds like a good one... But the skinnies up front won't work.... i to road racing/autocross. Don't really care about dragin, unless some punk thinks his sh*t don't stink at the light... and I'll quickly put them into place.

My car weighs right at 3000 without the driver I have eliminated the following:
manifolds for headers
custom radiator mount for the becool rad
replaced the sawblades for draglights
removed the radio
removed the A/C and heater
Removed the passenger airbag
removed the parking brake
removed the ASR/ABS computer,wireharness and all the solinoids and brake lines.
removed the spare, jack and all the carrier mounts.
removed the front swaybar.
Removed the rear inner fenderwells.
This winter I plan to change the headlights out for a set of fixed lights (tired of doctoring up the headlights every year)
a lexan rear window
lighter carpet
replace the steering wheel with a non airbag type.
weld in a full roll cage
Replace the seats with a kerkly seat
CF roof panel
And if there is any money left over a CF hood.

Also, does the newer style dash/consoles weigh more than the older flat style? I assume they do but how much? Thanks

lexan windows will scratch on the doors, but in the rear they dont see too much damage because they dont get hit with anything, except dust, i know there was a group purchase for them in the forum awhile back and they said you'd save 60 lbs, and also removing one of the hatch pistons which hold up the rear hatch could shave a few ounces
remove headlights and motors and install piaa driving lights in your fog light location, maybe ten pounds.
magnesium wheels all around, they only weight 11 lbs a piece.
