I know I’m beating a dead horse but what did you guys do to get to sub 3000lbs without messing with the interior.

jayyyw

i got to 2800lbs with full interior and a/c.

449er

Curb weight of a C6 Z06 was 3,131 lbs, not sure how you could drop 131 lbs without touching the interior?

Search for Jim hall’s build. I think the documented weight savings. Without touching the interior it will be expensive, but easily do-able. A 1lz with carbon brakes and carbon wheels alone will be close to 29xx

Silver Bullet C6

Lithium battery (and charger), LG GT4 cat back, smaller/ lighter Weld wheels and tires should get you close to 3000 lbs. Going much lighter will likely be considerably more expensive or require deleting parts from the car.
Lighter seats would probably get you more weight reduction, but more cost too.

Im looking to build a production run of carbon fiber McLaren Senna like set seats that'll drop the weight of each seat significantly. I can keep you on an email list if you want. That'll get rid of 50 pounds likely

Stock seats aren’t heavy...not sure why everyone always says they are. It’s the electric motors under the seat that has all the weight. The seat itself is aluminum and fibreglass with foam.


Id also focus on reducing weight in the front of the car - not on the rear. Car needs as much weight as possible on the back to help grip during acceleration.

449er Only the 2006 and the 2011 Z07 option equipped Z06's weighed in at your number. The 2007 thru 2011 versions, exclusive of extra options that might add a little extra weight, were 45 to 50 lbs heavier. 2012 and 2013 were slightly more than the earlier models thanks to an extra pair of cats and slightly larger seats based on what I have been able to determine. Best weight determination is your own car with 1/2 tank of fuel and a very accurate scale but these numbers should serve as a good ballpark prior to any extra add ons or take offs.

My 2009 track car with Carbon Ceramic Brakes, Carbon Fiber hood, roof, and valve covers, fixed racing Sparco Seats, Fidanza aluminum flywheel, and 18 inch Forgeline wheels is knocking right at 3,000 lbs with a full interior (minus factory seats of course).

How light are two piece rotors compared to carbon I was thinking either 2 piece up front or zr1 brakes and 15 conversion in the rear

passagemaker43

Depends on the manufacturer and the racing application of the rotor. Stock fronts are 26 lbs. Carbon Ceramic fronts are 13 lbs. Coleman (Zip) 2 piece lightweight street application is about 16 lbs. More heavy duty racing quality 2 piece rotors are about 20 to 22 lbs depending on who made them. Cost make the CCB's expensive for racing. In street use, excluding any vibration issues that sometimes occur, they should last 100,000 miles.

Corsa Sport or Extreme muffler the new ones (late 2020) are about 15-20 pounds lighter than oem which i think come in at 54 pounds including the over axle pipe.

It was pretty easy but I was also willing to go further than most people.

My 2008 is 3,141 as follows. Getting to 3k would require a ton of work or an empty fuel tank 😝

- full tank of gas (100lbs)
- Forgeline wheels (18x10.5 and 12.5 w 305 and 335)
- Essex AP racing full brake kit (calipers and rotors)
- Sparco evo seats
- Stock exhaust
- 20lb flywheel

I think you could drop 50lbs w the exhaust. From there you’ve got to start going to carbon hood, gutted interior. Etc.

double06

I think the TR6060 is like 20 pounds heavier than the T56 but maybe a transmission guy can chime in on that. A lighter clutch would help. But as one person mentioned above at what cost do you want to get there (and not just money) but just making the driving experience worse or something like that. For example at the drag strip you might see someone with an old car with say the inner fenders taken out (you know with all there wiring is zip tied to the fender) or the all the carpeting / interior taken out and its a driver car (not a true race car). They might have saved 100 pounds but it looks like crap, drones inside, and the inner fenders actually provide structural support - they would have been better off adding 15 hp to the car to make up the weight loss before ruining the car.

The good news on these cars is we are starting from a fairly light weight to begin with.

I got mine down to 2815. Still have AC but replaced the seat brackets with aluminum ones that I made. They weighed 1 pound each vs 26 and 12 for the stock brackets. So leaving the stock seat brackets the car would weigh 2851.The only other interior part I removed was the passenger air bag at 12 pounds. That thing is a monster. .I'll list some of the heavier things I replaced but not a whole lot of smaller ones
two piece brake rotors 32
Magnaflow mufflers 30
Braille lithium battery 25
Mantic twin disc clutch and flywheel 22
Kooks headers 20
Carbon fiber hatch 20
Factory carbon fiber hood 15
Lexan rear window 15
Michelin tires 18
Windshield washer tank 14
TOTAL 196

Nursing Nevada

Any pics of those seat brackets you made?

449er

Less weight is obviously better performance, but I personally would draw the line in removing air bags, windshield washer tank, & a Lexan back window

Harmonster, I think you've done pretty good. Most stated weights are with 1/2 a tank of gas. Take 50 lbs of gas off and you are already at 3091 Lbs. A carbon hood weighs 15 Lbs, half of the stock hood, You haven't mentioned headers but that would be worth about 20 Lbs. Not sure what your brake weight savings were and I know the CCB's are super expensive but compared to a stock system they save pretty close to 50 Lbs. A good aftermarket clutch should be worth close to a 20 lb saving. The hood, headers and clutch would get you within 35 Lbs of 3,000 with a full interior. I call that excellent given all the heavy stock parts that would remain. Find a good set of CCB's and you will be knocking at 3,000 lbs.

What's the problem with a Lexan window? If it's good enough for a Mach 2 fighter jet canopy it's good enough for a lowly 200 mph Vette. LOL
