with the added 70 ~ 80lbs (either A&A, ECS or Maggie) and higher center of gravity on the front (Maggie), do any of you notice any difference in suspension height or change in handling?

thanks for chiming guys/gals

Its a 3300 lbs+ car with you in it. A set of headers will drop approx. 20lbs from the engine, so when you add a 70lbs blower, you have 50 extra pounds or so at the front; you will notice that the front end does drop some with the blower in place (I had to re-adjusted my ride height after that), but the actual balance of the car shifts by only 1%, which is not something you can notice, even when driving near the limit.

thanks Sam....

Just go on a 50lb diet yourself to make up for it...

HeadPapago

I would if I could........

To answer your question, no, you won't notice any difference. Do you notice any difference from a full tank of gas to 1/2 tank? I suspect not.

*numbers are approximate*:

Supercharger, installed: +-65LBS (you add the blower and intercooler, but remove the stock intake, stock idler pulley, stock radiator shroud and other misc. items)
Aftermarket Headers: -20lbs
Twin Disc Clutch: -20lbs
Braille lightweight battery, stock location: -20lbs
Braille lightweight battery, relocated to trunk: -17lbs, -53lbs for the sake of weight balance (stock battery weights 36lbs)
Stock battery in trunk: -72lbs (effectively for the sake of weight balance)
LG Coilovers: -20lbs (Manufacturer claim)
Carbon Fiber driveshaft: -3lbs
Stock C6 seats: 60lbs each (heated / side airbags), Aftermarket seats can remove 30lbs or more from the car depending on make and model.

My car:
Wheels/tires: -16lbs
Monster Stage 2.5 clutch: -16lbs
American Racing 1 7/8" headers: -18lbs
*soon*:
Optima 34 in trunk: -10lbs, 46lbs effective.
Lightweight 2 piece rotors: -12lbs

So my car will weight approximately 7lbs less than stock
And the weight bias will be shifted to the BACK by 15lbs as compared to a stock C6 (which does have a slight front weight bias from the factory).
Without removing anthing and making no sacrifices in comfort...

PowerLabs

Good point. The weight of a full tank on a Corvette is 113pounds; almost TWICE what the blower weights

For what its worth though, I must point out that my car does hook up a little better on a full tank That's part of my motivation for moving the battey to the trunk...

always better/detailed posts from an engineer

Your nose will drop and you will scrape air damn just about everywhere until you raise nose back up... Don't let this discourage you though, just depends on how you drive.

Once you raise it back up its negligible, but certainly more then half a tank of gas unless you shed weight elsewhere.

Plus your removing some other parts like the stock belt tensior,radiator shroud plus the inner support panel . Like power labs said when adding headers your removing the cats and heavy cast manifolds. With the ARH's the cats are alot futher back and much lighter! When doing both Arh headers and a A&A kit!* I can't see any thing more than a even 40 pound gain to the front end! Only thing I noticed was the lowering of the raditor cradle lowered the airdam.*

yep mine dropped some, but it can be readjusted with the front control arm adjustments(but they are a pain in the A$& )

HeadPapago

Thanks a lot guys

Now I'll have to shop for a system..... that'll be for a new thread soon...

Had my car weighted:

3180lbs after subtracting my weight and the fuel in the tank.

HeadPapago

WOW.... 37 lbs. lighter than stock weight of 3217 lbs.

PowerLabs

My car is a 2LT (no HUD, no seat heaters) so I thought the factory advertised weight for it was right around 3160lbs?

HeadPapago

I got the 3217 lbs. figure from edmunds.com

I have the ECS 1500 kit, it's about 60lbs. I did notice a little more scraping, very little. We raised the front end adjusters a few turns. As far as handling goes: What makes a HUGE difference is ripping out the toy factory C6 sway bars & putting in Hotchkis or similar. I also relocated the battery to the rear pass cargo area. (I like both these mods a lot)

I did not notice a difference, but I have poly a-arm bushings, Pfadt comp bars, LG coilovers and Hoosier A6's all around. I also had the car lowered and an alignment done after everthing was installed - it handles very well.

Advertised weight is wet weight (full fluids) which means a full tank of gas. My car (1LT) weighed 3170 with 1/2 tank of gas, so figure about 3225 full weight. Trust me, the Z06 guys take these figures seriously. My 1LT is fairly close to an 09 Z06 (the heaviest Z06 ever).

Sam, you would probably have to add at least 110 pounds to your weight, which isn't bad considering your supercharger and 2LT. Your headers definately saved you some weight. I'm just now starting to get into the weight game with this car.

I think one thing that is nearly as important as weight is weight distribution.
