well i havent done much yet...

removed, tire inflator etc... -5~
removed winsheild washer fluid, resivoir, and pump. -10~


next up.....
remove a.i.r pump, and lines -15~
lightweight battery.... -25~
and LG pros with off road x-pipe -30~
and MAYBE some 2 piece rotors.... -15~

do you think that is enough to get me to 3000.?

i havent weighed my car just yet.....

 

No. I think we start around 3150. I am normaly 3040 with CCW drag pack, and 1/4 tank. I finaly remove all the crap (cleaners, detailers, tire inflator kit ect...) from the car and the front sway bar. Big delta for the launch. Swapped out front shocks for QA1 Rs up front and might have got a few pounds. LG pros got me 30 maybe. Good sticky under general tech I think. Need to see what it is down too before my roll bar goes on and the battery relocation kit.

Stop eating at McDonalds!

 

I lost 60 lbs of my own body weight and never run more than 1/2 tank of gas. Thats the easiest way to do it.

 

I added a trailer hitch and reversed 20 million dolars in General Motors R&D.

 

Funny but true

 

Seats, remove passengers,

 

My ASP, SCCA solo class car-------

04 z06 silver
Carbon hood from CE model
Lightweight flywheel
No A/C
No Radio, and no speakers of course
Sparco Evo seats
Headers
Stock mufflers
All pollution controls gone
Lightweight battery
Sparco wheel to replace stock wheel
Hoosier A6 tires
CCW 18x10.5 all around
5" rear element for more downforce, don't know if it works, and it adds about 4lbs or so but it looks cool

Weight----about 2900 lbs with 1/8th tank

Go Team ! Itchy *****
(Car was 2006 ASP Pro-Solo Finale Champ---with my buddy Hector driving---I did worse)

 

Great thread first of all!

I am a reformed weight weenie from the Supra world, and made it a practice to catalog everything that I either removed or added to my previous car.

With the Z06, I don't feel the need to do this (yet) as I want to retain comfort wherever possible. However, I have some observations and questions regarding what has already been posted in this thread.

Observations -
Our cars weigh 3116 - 3120 pounds fully fueled. Since there are no significant options on C5 Z06, in terms of body weight, this is largely agreed upon. I did remove my BSMs which *might* be worth 2-3 pounds altogether.

Also, I'd discourage the use of a true lightweight battery unless you have either a great battery disconnect system or a battery tender, as I did used to use the Hawker PC680 (14.5 pounds) in my Supra, but if I left it hooked up the battery would be fully drained within 9 days or so.

Questions -
Where can I find out more about removing the a.i.r. pump stuff? That is a subsational amount of weight. Are there any downsides to that mod? (I assume tuning is required to not through CELs at minimum).

Suggestions -
Look into replacing your factory seats with something like the Sparco Roadsters if you want to lose significant weight and also gain performance in terms of lateral support. Even with the aftermarket rails, this mod would lose considerable weight.

Fixed headlights are also reputed to be worth about 5-8 pounds less than the pop up units. I'm considering those, should I find a set that are both reasonable in cost and also of decent quality. Losing weight at the extreme front end of the car is also a very good place to do it.

Again...fantastic thread!

 

Mine weighed in at 3050 with the stock wheels, now I have lighter weight wheels, bet its about 3040. These things are pretty damn light, even the back window is thinner than the stock C5's. BUT(!) if you really wanted to go extreme do what LehmanZ06 wrote.

 

For weight reduction, start with rotating mass.
Lighter rims, tires, rotors, driveline all have a pronounced effect.
General consensus is 1lbs of rotating mass effects like 4lbs. of static.

I replaced my power seat driver’s cradle with a manual one. The power cradle feels like it's more weight than the seat's themselves. Then the usual stuff like radio, speakers, air conditioning pump, etc. All depends how drastic you care to go.

 

The biggest things to cut weight on are the unsprung weight and rotating mass. Wheels, tires, rotors are both and will give you the greatest benefit.

Instead of adding more power for the C6 Z06, I'd rather see more money spent in the future on lightening the car even more. I don't need a 650 hp blown Corvette. I'd rather have the car the way it is now only with less weight.

 

My kind of philosophy right there.

 

At least they are paying attention to weight. I don't know what Ford is smoking by giving us a 4,000 lb Mustang with the Shelby GT500. That's just rediculous. Shelby must be losing it because it sure doesn't sound like anything that he would normally put his name on.

BTW.. When Carroll Shelby worked on the Viper prototype, he gave them a 2,800 lb car. It was 3,500 lbs. once it made it to production. The Viper needs to go on a major diet as well.

 

My car weight 3160 with a full tank of gas, some tools and my exhaust having been done.

 

AIR system is maybe worth 10 pounds, I took system off and there is no downside. Weight, cleaner engine bay, and performance are gained. Edit needed is all.

 

I'd say the best way to reduce weight is to go on a diet. think about it you spend less money on food and you get more speed

 

I appreciate the information...and will try to search around for more. I assume you can only remove the system if you go to aftermarket headers without the provision for the system, right?

 

Will the car pass emissions without the A.I.R. system? Lehman's car is a race car, so I don't think he's worried too much about it.

 

Yes, as long as you edit code out and don't have underhood inspections.
