Anyone have this Lacetti data handy?

I'm looking for....

Frontal Area
Coefficient of drag
Front/Rear weight distribution

Don't think I've seen any published specs on this info.... I weighed my Optra once but I have no idea what I did with the figures.

For some reason I think I remember there being a review about the forenza saying something about it's coefficent of drag.... but that was a few years back.... no idea where it was.

I got the weight distribution by doing a drive to a truck stop...

Still in need of the aero, but am working on getting it through CFD. It's not mandatory that I have it until the 1st of the year

What was the weight at the truck stop ?

Stock Forenza 5-speed without me in it and a full tank was right at 2876lbs

Front was 1630lbs = 57%
rear was 1240lbs = 43%

(slight difference is due to style of measurement with wheel overhang on a slope)

Actually much closer to a good balance than I expected... seems the rear suspension is heavier than I imagined

Did you get in the car afterward too see how acurate it was?

Someone locally tried two different truck stops and said they were both wayyy too far off.

Plus that seams a tad high, I think I did ~2650# without my rear seat, but with my subs, with 20lbs wheels, lowering springs, axle back exhaust, probably intake, and maybe a few other bits. Oh and I had nearly a half tank of gas, if I remember right a full tank is about 115lbs.

It also depends on the options you have in the car... the factory options vary by quite a bit in the weight. The manual shows weights varying between 2670 and 2832 depending on transmission and trim option... in dry state... so add the cooling system, oil system, and fuel system.

And I'm pretty sure it was accurate, it was within 5 lbs of my bodyweight while standing on it...
