So how much does it weigh now?
So as you all know my car is a base model automatic 89.
Interior carpet and all padding are now completely removed except for door panels and will soon be replaced with light auto carpet.
All interior plastic panels are gone, (check F/S sale thread for proof) except for rear view mirrors.
Dash and everything related to it are now completely removed and will soon be replaced with aftermarket guages.
A/C system is gone for good, used shorter serpentine belt rerouted over the tensioner instead of under,
ABS system has been eliminated.
Have manual seats racks, but using still stock seats.
Using a carb system with all the non-essential smog stuff removed. (check sig.)
Using some old 16" Centerline rims with skinnies on the front.
Using clear targa top.
Car still runs and has the street legal items, i.e. headlights, brake lights, mirrors, etc...
My guess would be 2600 lbs. Your guess?
Anymore ideas on weight reduction? I want to have the lightest, street legal C4.

I don;t know how much you will weight with those mods, but 2600lb is pretty light. I mean that would be REAL light. My guess is that your barely under 3k lbs.
To get to 2600 beans you would need to have lexan rear, lightweight hood, lightweight front runners, race rear wheels. likely aftermarket race brakes on 4 corners, no lights in the thing, and just about everything else gutted out of it to make that sorta weight.
I have seen all out sheetmetal (aluminum cars) weight in and they are still over 2600lbs. IMHO you will not have a street legal car at 2600lbs. Maybe I am wrong but if you do I would like to duplicate whatever you did to get there, unless it gets crazy as I sitll running mine on the street.
do you have any photos of it? Have you weighted the things you removed?
Good luck, weight is the easiest way to quicker times. I just can't force myself ot tear my car apart.

We have a truck scale at work that is always calibrated. I run my semi accross everytime I leave on a run. My 88 automatic coupe, with me in it (220 lb), and a full tank of gas, tips the scale at 3000lb on the nose.
I would say you are down there, but 400lbs worth??? Maybe!!!

I am in no way trying to be confrontational here, but are you sure of the low range accuracy of those scales? You and a full tank of fuel (at six pounds per gallon) would be approximately 330-340 pounds. This would mean your car is less than 2700 pounds dry. Unless it's a stripped racer, that's just not possible. As I said, not trying to start anything here, but can you elaborate on what changes you have made to the car?

The low range accuracy of the scales are dead on. I have stepped on the scale by myself, and it reads 220 on the readout. It is another nice day here in SW PA, so I will be taking the vette to work again today. I am down to 1/2 tank of fuel, but I will put the car on the scale, and see if I can get a picture of the car on the scale, and the readout on the wall all at the same time. There are no mods done to the car, and it is bone stock from the factory. I was suprised with the weight myself. I never imagined the car was that lite. Both these scale are very acurate, and need to be because of DOT rules.
Wish I had your car with my motor, trans, and rear.

My '84 with an almost full tank (full minus a 40 mile drive) weighs 3345 without me, on the race track scale. I have my serious doubts on both the 2600# and the 3000# claims.

There is a mistake somewhere. Re-weighing the car on the original
scales and on two other scales will support what people are saying here.
Incidently, NitrousSam is perhaps the most knowledgeable member on
this board regarding how to achieve weight loss on a C4.

Don't know if this helps but my 84 which I bought because of the weight & price, weighed 3000 even with full interior (aftermarket carpet), no AC, no smog equipment, & an aluminum headed 400 SBC with a carb (wiring was stripped to only what was needed). The 3000 on the money figure came from the guys scale read in 10 or 20 pound increments.

Here are two pictures of my 88 on the scale at work. If you click on full size photo, you will get a clear look at the readout. These are certified DOT scales, as 100lbs over weight with our trucks will net me, and the company a stiff over weight ticket. The first on is the car with 1/2 tank of fuel, the second with me in the car showing fuel level, and I weigh 220lb.

Wow, that’s pretty cool
not sure what my car weight is but I’m sure is around the 2800lbs range, i have light weight carpet, carbon fiber interior, aluminum heads, sheet metal intake, aluminum rods, light weight hood that’s only 22 lbs, no side crash beams , fuel cell, i rewired the whole car, lexan hatch, i can go on all day, and the car has a narrowed 12 bolt with chromemoly parts. And super light wheels, my fronts are 7 lbs and the rears are only 14 lbs but they are 12 inch wide.

3240 lbs. from your picture + approx. 60 lbs for 10 more gallons of fuel = 3300 lbs.
Still pretty light.
My 88 weighed in at 3130 lbs. with 3/4 tank last time I had it on the scales (each corner).

Mine weighed 3160 with half tank of gas and no driver. I weighed it at a dump on a truck scale. I had removed EGR stuff, cats, air pump, spare and jack, and replaced exhaust manifolds with headers.

Just had mine weighted too. 3150 without the driver and a quarter tank of gas. No emissions, no spare or jack, no stereo or antenna, removed other misc parts. A/C is probably 50 but I haven't given it up yet.
