My 2006 C6 Z51 with various modifications came in at 3239# with half a tank of gas. 867# LF, 831# RF, 757# LR, 784# RR. Add in 200# for me, shuffle things a little, and my final weights were 929# LF, 861# RF, 849# LR, 806# RR... 49.6% cross weight, 51.9% front, 51.6% left side.

Just curious how other folks typically have their weights end up. 861# per corner would be perfectly even for me at 3444#. At that weight if I could get 51% F, 49% R the fronts would end up 878# and the rears 844#.

For the record, I had stock bars and stock endlinks, with my weight and the bars connected: 936# LF, 849# RF, 835# LR, 820# RR. Disconnect the swaybars: 925# LF, 860# RF, 846# LR, 808# RR. I was pretty shocked by the weight change there. The bars were nice and free, shimmed as necessary, VBP poly bushings, but stock endlinks.

My 01Z came in at 3400 with my fat ***, 1/2 tank fuel, and 75lb of ballast in the pax seat.

Unfortunately, I don't remember what the corner weights were, I should find another set of scales and do it again.

I had my 08Z weighed (no adjustments done) between sessions at Laguna - Full tank, me inside (188+cloths+wallet+helmet and stuff), R6s 315/18 - 345/18, Hotchkis sways connected, yellow top batteri.

Total 3375:
Front: 842/818 - 49.2%
Rear: 875/842 - 50.8%
Cross 50.1%

Never thought much about it as I haven't seen any comparisons.

I just put z06 catback on and saved 18 lbs approx I think. Should lower overall weight to 3449.

Too late
But a random sets of events lead up to this point, so it may still get back there.
Well, not really random; the guy that did the measuring said he rarely worked on vettes as they were very close from the factory. - He gave some horrible examples for other cars, but I don't recall which.

What were your lap times at Laguna Seca?

Nimo

1.44 with some traffic, but the stock springs were getting too soft at that point. Fixing that now

Got my car checked today with street tires, full tank and 185lbs dead weight. Now with coilovers.
- Car was not adjusted as difference was within acceptable variance. (Porsche specifies 40lbs as the limit for adjustment, GM doesn't have one?)

Total 3401
Front: 844 819 -
Rear: 895 843 -
Sum Side: 1739 1662 51.1%
Cross : 1714 1687 50.4%

While it looks like the car gained weight since last time, my street wheels are heavier (19/20 combo vs 18/18).
Track wheels are 212.5 and street wheels 247.8, so 35.3lbs more.

longdaddy

damn and I though i was heavy - 3350 with half a tank of gas, driver, oem c5z wheels. that's with a beefed up rollbar but before i switched to coilovers

cross distribution was very similar to Nimo's, I can't find exact numbers.

Nimo

Not sure about heavy? - Mine would be 3305 with half a tank, me and track wheels.
3401 - 35.3 - 60 = 3305.
(full tank is 112.5, assuming 6.25 per gallon for 18gallons)

I think I may have added weight with my coilovers as the stock C6z springs were very light. Stoptech 15"/14" also added weight.

For as well set-up and as light as my car is I should be faster. My T1 buddies would kill for these numbers. That's me in the car and with electric windows that still work and 1/4-1/3 tank of gas I forget now. Maybe my scales are broken?

Here are my weights with my 2006 Z06 with coilovers, a 12 qt dry sump, 1/4 tank of gas, and my 200# fat ***.

LF - 856# RF - 827#
LR - 848# RR - 793#

Total - 3324#

Cross - 50.3% & 49.7%
Rear - 49.3% Front 50.7%

I have the Pfadt sways with adjustable heim links. Adjustable links are a must if you want a neutral setting for your suspension.
