Default How much do C4s weigh and how can you bring that down?

How much do C4s weigh (and what years) and what are some ways to bring that down without removing the AC and radio? (replace body parts? tubular parts? etc.)

C4 weights vary almost infinitely, depending on year and options. You can figure about 3250lbs as a very rough average.
How can you bring that down? The very same way you reduce weight on any car: take anything you don't want/need out of the car and replace what you do want/need with lighter stuff.
The first part will be fairly cheap. The second will not.

You want specifics? There are a few guys here who have made weight reduction a religion and they should be dropping in any minute with long lists.....

You seem to be on the right track, though. Most guys just want better acceleration through increased power. Losing weight not only gives you better acceleration, but better braking (and brake component wear), better turning, increased tire life, and better fuel mileage; how can you loose??!!!
Good luck and have fun!

Carbon fiber body parts, specifically the hood. But, very expensive.

there is also a lexan rear window available.

remove the A/C, carpets, insulation, stereo... but if you are going racing, any weight you remove will be replaced with roll cages and the like.

Also, use a clear top, they are lighter than solid tops. Even lighter is a targa truss, it's a tubular top replacement thingy.

if you are serious about racing, something like the Breathless LeMans lights would rock...

lighter seats, remove the power rails.

I think the lightest C4 on the forum is around 2900 lbs...

Heres what Ive done to mine (93 vert):

1. No cats, long tube headers in place of stock cast manifolds (est. 45-50 pounds weight savings)
2. Took out A/C componentry (AC delete bracket installed) ( 35 pounds in weight savigns)
3. Took out spare tire/jack (35 pounds weight savings)
Lightweight AL 12 pound flywheel (30 pounds weight savings)
4. Removed passenger seat on drag race days (saves 40 pounds)

Thats the easy stuff.

Other stuff you can do is:

1. Lightweight tires (the Eagle F1 supercar tires, due to reduced skid depth and the BFG drag radials both weigh less in the same size than competitor UHP tires. They are about 4 pounds per tire lighter. 4 x4 = 16 pounds unsprung weight saved)
2. Lightweight rims (your stock rims are pretty light, if you upgrade to GS rims, go factory OEM vs. the heavier AFS)
3. Lightweight hood. Due to the size of the hood, I think you can save 45 pounds. (exotic muscle sells these)
4. Lexan windows (exotic muscle sells these I think for our C4)
5. Take off doorpanels (probably 8 pounds of weight per each one)
6. Remove side windows and replace with nets.
7. Get 2 piece rotors to replace your front solid 13" rotors (Baer Eradispeed). Saves about 6 pounds unsprung weight total.

By the way, my 6pt roll cage weighs 35 pounds.

Last but not least...

Dont forget yourself...Maybe its time you go on a diet (just kidding, I had to throw that in there).

There is actually one in the for sale section that weighs that much and its got a 4xxCI engine in it

Exotic muscle sells lexan windows if your interested.
Removing headlights, spare tire, A/C, radio/speakers....depends on how far YOU want to take it

I know this has been mentioned already, but I think taking out the radio/speakers would save about 9 lbs. The head unit is at least 6 lbs.

It all adds up.

Good luck.

Do a search for weight reduction posted by NitrousSam. He had a thread a while ago that got to be pages and pages long with killer ideas.

Odyssey PC680 battery weighs 13lbs vs. the 38lb stocker.

Pretty good weight drop for $100.

I just removed the front skid plate and made up new brackets for the PS cooler. Probably 20-25 lbs but stay away from parking sleepers.
