I've started trying to shave off extra weight off the car just to see how low I can get the car to and obviously help with performance. I also wanted to know if any owners have weighed their car after weight reduction and where their weight was saved.

This is a list I've compiled from electronic scales and other Corvette member's findings. Hope this helps!

Caravaggio Race Seats - 38lbs for pair - Saved 33.25lbs over stock seats
Removed both floor mats - Saved 3lbs
Removed Tire Inflator Kit - Saved 5.75lbs
Removed Owner's Manual - 1lb
Removed Fuel Rail Covers - 1.5lbs
RacingBrake 2pc Rotors - 34lbs for fronts - Saved 18lbs over OEM C6Z06 rotors
Trickflow 215 heads - Equal weight to stock Z06 heads (243 casting)

1 gallon of gasoline weighs about ~6lbs to 6.5lbs. Full tank of gas on a C5 Z06(18 gallon tank) weighs 117lbs. Gas tank with an 1/8 tank of gas weighs ~14.5lbs. This is assuming the gas weighs 6.5lbs per gallon.

I'm running aftermarket wheels also with a hefty sized tire. CCW told me that my 18x12 C10s weigh ~19lbs per wheel. I am unsure on how much my 335/30/18 Nitto 555Rs weigh. They also advised my 19" CCW SP500s weighed about 22lbs per wheel.

Still trying to get exact weight differences on the FAST 90mm Intake vs stock intake manifold, stock C5Z06 headers vs. Kooks 1 3/4" (30lbs per Kooks website), stock C5Z06 x-pipe vs Kooks x-pipe (30lbs per Kooks website).

The FAST 90mm intake box claims their intake manifold weighs 11lbs over the stock manifold weighing in at 26lbs. I sent an email inquiring about the exact weight, so we'll see.

I also sent Textralia an email inquiring about the weight on their OZ700 clutch w/ aluminum flywheel vs. the stock LS6 clutch and flywheel.

I will try to get the car weighed in when I can find an accurate car scale in the metro Atlanta area. There's a racetrack that is almost 2hrs away but I don't know when I'll make my way back.

Feel free to add or correct my numbers, lol.

dont forget the driver weight also. Keep us updated on the weight factors

the stock intake does not weigh 26lbs...maybe 7-10lbs...

I think thats the entire intake not just the top IMO.
Light weight wheels and brakes are great due to rolling weight. Driveline components lightened are a nice gain aswell. Its one thing to take weight out of the car, but to take rotated weight is all the better.

I could see 26lbs for the intake manifold, filter, tubing, air box, clamps and air filter

How much do like my C5 weigh stock?

My 2004 coupe weighed 3280lbs with 1/2 tank gas......

That is about what mine weighed, a 2000. Right now I am starting to put it on a diet. It is about 3600 pounds because of the rollcage, iron block stroker, and F1-R supercharger. I am still going to keep the full interior, radio, etc, but I would like to get it down to under 3500 pounds.

From Corvetteforum:

Weight reduction
You can achieve substantial weight reduction with the following modifications, while still having a car that's very comfortable to drive. Most of these modifications will directly increase (and decrease in a few cases) the safety of the car, while safety is indirectly improved due to the better handling and limits of a lighter car. Fighter pilots say "speed is life". Acceleration, deceleration, and lateral acceleration are all forms of acceleration, and lighter cars accelerate better in each of these ways because the tires have less mass to control....thus a lighter car is a safer car. Lighter cars have better moments of inertia which allows them to turn in more easily and roll less. Lighter cars are also easier on the tires and gas.

All the stage weight estimates are typically wild butt guesses, but it makes it easy to see what is possible. The weight listings in the separate weight posting is MUCH more reliable.

Stage I: Streetable weight reduction mods

Non-popup headlights (~40 lbs)
Braking rotors with an aluminum hat, or titanium rotors (unproven on street cars) (~20-30 lbs)
Carbon fiber hood (~12 lbs)
Z06 (thinner) windshield and side windows (~5.7 lbs)
Non runflat tires (~20 lbs)
Slicks (~30 lbs)
Z06 wheels (~4 lbs est.)
Corsa titanium exhaust (~35 lbs)
Long tube headers (~20 lbs)
Halltech aluminum alternator & bracket (10 lbs)
Carbon fiber driveshaft (~2 lbs)
Newer torque tube
Less options [HUD, elec AC, Active Stability, seat/mirror/steering wheel memory, cd changer] (~50 lbs)
Less gasoline & wiper fluid (No wiper fluid=9lbs, 6 lbs for every gallon of gas in that 18 gallon tank....~81 lbs for autocrossing)
Remove
cargo net
targa top (~20 lbs)
BCM’s
C5 "appearance mods" - exhaust plates, doorsill covers, etc.
fuel rail covers
all loose change, CD's, golf clubs, misc. items, from center console, hatch area, and glove box
Replace
stock crank pulley with aluminum aftermarket pulley
steel dampener with aluminum dampener
stock targa top with lexan piece (coupes)
water pump with electric water pump
battery with smaller battery
non-stressed fasteners with aluminum or titanium fasteners
leaf springs with coil over shocks with titanium springs
steel shifter with aluminum shifter and delrin or titanium shift ****

Empty your pockets of extra change, PDA's, cell phones, keys, lead plates, or whatever other junk you lug around
Go on a diet =p

Stage II: Hardcore semi-streetable weight reduction mods
Aluminum flywheel (~10 lbs)
Lighter clutch like Exedy or Quartermaster (~10 lbs)
Racing buckets (40-50 lbs)
Off-road x-pipe (10 lbs)
Replace stock hood, fenders, doors, roof, hatch and bumpers with aftermarket carbon fiber pieces
Remove
Tire repair kit (Z06)
Floor mats
Fog lights

Stage III: Track only weight reduction mods
Racing steering wheel & delete both airbags (~30 lbs, but get a 4-6 point harness)
Use unpadded aluminum or carbon fiber steering wheel
Run open headers
Replace stock front and rear glass with polycarbonate “glass”
Rebuild motor with Al or Ti connecting rods, Ti valve spring retainers and pushrods
Port the heads
Replace valve covers with magnesium or carbon fiber parts
Strip entire car, acid wash chassis, put car back together.
Remore
Column locking hardware
Interior – passenger seat, carpets, speaker panels, head liner, dash, center console, glove box, door panels, sun visors, rear view mirror, insulation, etc.
A/C Compressor
A/C controls and ducting
AIR pump system
Factory radio, speakers, and/or CD changer, and unnecessary wiring
HUD projector
Windshield wiper fluid reservoir and pump
Windshield wipers and motors

Fender wells
Headlight assembly, turn signals, taillights and reflectors
Shave side mirrors
Torque tunnel cover
OEM seat belts
Parking brake
Side windows and motors
Power locks and power windows
Side impact beams
Casting flash from engine, then polish

Reducing unsprung weight—not all is streetable
Forged 1-piece wheels
Use 3-piece wheels by Jongbloed, Kodiak, CCW, BBS
Skinny front wheels (drag only)
Ti fasteners on 3-piece wheels (~1 lbs per wheel)
Lighter non-runflat tires, or even track only synthetic corded slicks
Lighter calipers
2-piece, unvented or titanium rotors
Titanium wheel studs
Aluminum or titanium lug nuts
Remove tire pressure sensors
Remove rubber valve stem cap
Balance the wheels without tires or balancing weights, and then mount tires

that is what is in the FAQ I referenced. All the items plus the weight...

My stock 2002 Z06 weighs 3021 without me in the car, and 1/8 tank of gas on the scales at HRP.

My 02 z is lighter than I thought. It weighs 2920 with 1/4 tank of fuel and stock wheels and tires. the stock wheels and tires are lighter than many think. My interior is completely stock. Most of the reduction came from custom exhaust work and lighter brake components. I have some fikses with lighter track tires and with some more brake changes and a lightwt battery I should be around 2900 with a half a tank.

SF-LS6

cat scales = 3030 with 1/4 of gas and dyna batt.
