I'm not too happy with the weight reduction threads. Iam just wondering how light do you think you can get your cobalt? I know mines like 2750...thinking if 2500 is doable? Granted 250lbs is alot of weight. What can spare,rear seats,interior really weigh :O) chime in anytime gents

 

Ditch all but the drivers seat, rear seats, all trim pieces, carpet, spare tire and all the stuff in the trunk, lighten the wheels, lightweight hood and trunk, eliminate the stereo, ac setup. That should shed some weight.

 

How much does a stock hood n trunk weigh compared to a cf hood n trunk

 

probably a difference of 20-30 lbs.

 

yeah and get rid of your power steering and do an ac delete yo!












jk

 

Probably like a 30lb loss.

 

you will loose 30-40lbs at least with cf hood and trunk

 

IDK about your car but on mine the Rear seat/passenger seat, everything in the trunk, carpet/sound deadening and spare/jack is good for 190lbs. Registration says it's 286Xlbs stock. then normal stuff that losses weight like getting rid of the airbox, exhaust, flywheel, battery/etc.

 

Anyone remember what the Grand-Am cars weighed? I wanna say 23xxlbs, maybe 25xx max? I know mine is 2990 with me in it and a full tank of gas. If you really want to get serious, ditch the sunroof (if you have one) for a carbon fiber plug, get rid of anything power - locks and windows if you have them. Kill the A/C system, get a lightweight exhaust system, and if you're REALLY feeling froggy about it replace the windows with light weight material.

 

What about the Time Attack Cobalt? How much did that weight in at?

 

I think it was lighter than the Grand-Am Cobalts because of the rules governing Grand-Am Cup cars. Now I'm interested....

 

Time Attack Cobalt was 2350.1 lbs. looking for my build book now, I think they have the curb weight of the GAC car there.

-lookin at my reg right now says 2733 so lets say your right and its 190 for that stuff(seems kind of high) but that would put my car at 2543. Say carbon fiber hood and trunk(give it 40) that would put it in 2500ish and ac delete and power steering well idk what that weight so all together youd be high 2400's and if u had hucker or nawes engine pushing around 200whp n/a :O) isnt that a quick car :O) i would feel like an american civic tho haha

 

That's for my car, I was just giving an idea. But if it seems high...

Stock Carpet 22.35
Floormats 6.10
Sparetire and hardware 28.70
Jack 4.80
Trunk Carpet and Pads 12.75
Passenger seat 43
SRT Rear Seat Bottom 10.10
SRT Rear Seat Back 29.95
Rear Middle Seatbelt 2.25
Sound Deadening Material 20.36
Firewall Mat (Bottom Half) 5.63
Rear Deck 3.96

Add it up and its 189.95lbs..

 

lol dont ever tell me to add after 12:00! ill take your word for it :O) but wouldnt mind seeing specs for the balt

 

as far as i can get


2440lbs

 

wait if you wouldnt mind listing..what did you take out spare,all seats except driver,interior,radio, this is what you had when running low 14's?

 

no. i have drag radial nitto 555 and a excellent track prep.
low 14 has been done with radio and and the thing between front seat.
i did some metal cutting.
removed trunk polymere.


on severe WR huck react different

lighter is always better

 

iam almost scared to ask about metal cutting lol.. Maybe carbonfiber hood and trunk combo in future shed some weight :O)

 

I got rid of my sub, spare and muffler.

If I had to guess, 50-60lbs?
Plus I lost 30 pounds physically.. hahah

My goal is a even 3000 lbs. but to really have an idea I would need to weigh my entire car somehow.

175LB driver, 55lbs weight reduction.

Wiki says my car should be 2,815 lb - 3,001 lb.. so hard to say what the final weight is.

 

yikes lol well when u buy a base model i guess the weight isnt there. like i said prior weight on my regi says 2733 so picture taking out those rear seats spare some back carpet...put on nice cf trunk and hood and thats like 200-300 lbs depending on hwo crazy you go with carpet and paneling

 

i have two trunks, one at 40lbs and 20lbs
