Weight Savings: Adding it up?
I dug around for awhile trying to find some solid numbers for weight savings with typical bolt-ons that are common of modified C6s - to no avail.
A lot of us are running lighter headers, x-pipes, cat-backs, and wheels. These are pretty common bolt-ons that in theory should be good for a pretty fair reduction.
Anybody put in the leg work yet to figure out what their theoretical weight savings is? I went from a stock exhaust to ARH 1 7/8"s LTs, 3" catless X, and SLP Loudmouth. I hear claims of the cat-backs being worth 15-25lbs depending on which brand / how agressive. My car runs a Spec 3+ w/ Aluminum Flywheel as well, and 4 18x11" CCW Classics (3 pc).
I'm just curious about where I should be, considering the car weighs something like 3240lb, stock (M6 F55 coupe).

Recently I installed CCW C10 wheels and Toyo R888 tires. 18X10.5 fronts with 295/30/18s and 18X13 rears with 335/30/18s. The tires are exactly 5 sizes wider than the stock tires they replaced (245/40 and 285/35). The wheels are 2 inches (front) and 3 inches (rear) wider than the stock wheels. I also installed some lightweight lug nuts. Total weight savings was 13.25 pounds. I was hoping to just break even on the weight, so saving weight is a nice bonus.
I also saved 16.6 pounds with a lightweight battery (Deka ETX18L). I was calibrating the TPMS sensors yesterday and left the car in accessory mode accidentally for 15 minutes with the radio on and my GPS unit charging. I thought maybe that would be an issue but the car started right up.
So, 29.85 pounds shaved off so far. I have a 4-wheel StopTech kit coming soon and suspension and sway bars to go on as well and I'll report the weight differences as soon as I get the new stuff on and the old stuff off and weighed.

i weighed my car in my race setup at an official CAT scale...2007 C6 1LT...my mods are in my profile...my race setup includes everything in my profile with 1/8 gas, no pass seat, kirkey race seat for driver side, gto spare wheels for the front with m&h bias ply front runners, c5z wheels out back with mt et street bias plys, and my new 6pt roll bar and harness...
my car weighed in at 2960 and i have a CAT scale cert to verify it...i even had 2 buddies there with me...i weigh about 170...so with me in the car it all weighs about 3130 in my race setup...before i put the roll bar in and with my old zr1 rear wheels my car weighed 2920 in race setup...by adding the roll bar and saving weight with the c5z wheels, i only went up 40lbs...
best thing for you to do is find a trucker scale to go weigh on...that way you know your true weight without having to guess

If I wasn't sitting in Iraq right now, I'd be in the driveway dismantling it and hauling parts off to the bathroom scale to find out... but bench-racing it from a computer to keep in good spirits has to suffice.

Regarding the battery, I've got the world's most electronically reliable Corvette... the 2005.
Right... The DBS eats through Optimas already, so a Braille battery or the like would be snuffed out in probably less than 24 hours.i weighed my car in my race setup at an official CAT scale...2007 C6 1LT...my mods are in my profile...my race setup includes everything in my profile with 1/8 gas, no pass seat, kirkey race seat for driver side, gto spare wheels for the front with m&h bias ply front runners, c5z wheels out back with mt et street bias plys, and my new 6pt roll bar and harness...

Anyone specifically account for the savings of swapping the stock exhaust for one of the Long Tube / decat X / open catback combos?

Z51 rotor's are very heavy, if you have those. There was been a couple of posts comparing to Baer +2's. Major weight savings, unsprung as well & rotating.
Hey "Oldmansan" by chance would you have a photo of those 295's on the front of your car? I really have myself backed into a corner as I have 19" front rims (not smart I know) there are R888 in a 295 X 19 available, I'm just concerned about the fit

The wheels and tires really changed the ride. The suspension and sway bars will go on in about a month as I'm going to install StopTechs all the way around first. I'll post pics as I go and weights as well.

And thanks to you as well... gotta give it to the guys who pave the way. Air Force here, too... and also from CA. Haha.
