and Ferraris are very heavy too . if i recall correctly they should be in the 3700 lbs range.
so our C3 are not that heavy at the end: that's why i've been not that concerned in overall weight reduction on my car but focused more on unsprung weight and F/R byas ( i have kept the steel leaves spring in the rear, for example)
would be nice if someone would post a search of curb weight of the main modern sportcars, just to have a reference

Actually this is just the beginning of weight, there will be no front bar, no mote flip up hood and hinges, looking for a set of non power doors to cut up. Cars gonna make right around 600whp so less weight the better.

Looks like I was tricked by Porsche curb weights. They're more optimistic than Chevrolet.
Just did a quick read, a regular Boxster is ~75 lb less than a Boxster S.
The S comes in between 2950-3050 "ready to run", no driver. (2006 model, limited options)
I honestly can't imagine taking much off of those cars without an immediate reduction in comfort. You can do headers and exhaust, I hear the factory exhaust weighs quite a bit.
I'd love to own a Boxster again.

Wish I knew, but I'm following in your foot steps with my 1980!
BTW, do you have a video clip of that exhaust setup? I've had magnaflows on 4 of my past vehicles. And I'd really love to hear your setup.

Another item to consider, many later GM p/s pumps are lighter weight than the Corvette OEM unit.

I just completed my rear end swap. I went from my 80 lb 3.55 iron rear end to a 60 lb 3.73 Dana 44 aluminum rear end for a 20 lb loss. Not a plug and play like you would expect.

Maybe I missed it but what about a Serpentine Belt setup. Most of the aftermarket ones use billet aluminum wich should be a bit less. And they will use the Gen II PS pump wich is avalable in Aluminum. Good by to the Clutch Fan for Electric if that hasn't been done yet. I'm under the impresion that the 80-82 Frames are a bit lighter. Maybe You can change that out and save another 10lbs or so !

That garage is impressively clean!!!!!!
wow
I really would like to see how your Vett handles in person... I'm over 300 lbs more weight...... Sure would like to see the difference....
The rack and pinion is a great reduction... Got mine tightened up, Dave had the same problem and I showed him where it was loose.... Took me a month to find it myself!
You will notice the reduction in turning radius, but you will get used to that quickly.
The other negative, or positive thing depending how you look at it is you feel much more of the road in the wheel, and of you hit a hole or something you get a greater front wheel shimmy.... Good for track feel, bad for cruising.... Do wish it had a little more dampening...

Speaking of headlights, here's a minor item I did years ago.
Not a big weight reduction (even with the bigger holes I drilled later), but it's way up front, and as I'm sure you've experienced, it gets harder and harder to find places to pull weight out of these cars.

2022 C3 of the Year Finalist - Modified
When does the car get so light that it won't stick in the curves? Just wondering if getting light does not have a down side. I am a pilot, so I am quite familiar with power to weight, but in the flying world you don't care about traction in curves. I am not suggesting weight loss won't improve things, but just raising the question. Is not the front to back weight balance important, the center of gravity of the car, etc. Duntov talks about the steel rear spring actually provided a low CG weight where the card needs it. All the weight reduction on the front end could possibly lose steering traction???? All questions to ponder.
