Going on a diet

teamgn87 · 07-12-2006, 11:57 PM

Besides the usual things(single exhaust and aluminum bumper supports) what else can I do to lighten up my 87 a little?Right now it weighs 3915 with me in it.Keep in mind this is a street driven car so things like pulling the door bars wont work.

ajt86 · 07-13-2006, 12:01 AM

fiberglass hood and decklid, aluminum core support, aluminum drums, remove the sound deading material

and the driver usualy can loose some weight too- thats free weight

teamgn87 · 07-13-2006, 12:06 AM

Where do I get an aluminum core support?And by the way I did lose some weight.Im down to 260.

Orlando_87GN · 07-13-2006, 03:28 PM

Some things I have done to my car:

GTA/GNX Wheels
Aluminum Core Support 12lb difference
Mini-Starter is easy 10lbs difference
Front and Rear aluminum bumper inserts 54lb difference

Things I still want to do:

F-Body radiator ~ 15lbs
Pat's Converter vs. stock converter
All RJC Aluminum Pullys
Hollow F-body front sway bar

I wish I had weighed my car recently but don't have any official numbers for you. I can tell you that my car sits too high in the front now but I think some '86 springs will fix my problem.

teamgn87 · 07-13-2006, 11:01 PM

Do all of the f-bodys have hollow sway bars?What year would i look for?This is a direct bolt in or are mods needed?

T Spool · 07-14-2006, 12:03 AM

3rd generation F bodies with 1LE option (16" wheels) have the 36mm hollow bars. Direct replacement for stock GN bars, save 9 or 10 pounds and handle better. I have a few of these to sell, but I need to look into shipping before I post them.

id be willing to take one of your hands when you find out what shipping would be.

MonteC · 07-14-2006, 08:40 AM

sound deading material is easy free weight to get rid of. take out the carpet and take out the back seats and pull up all of that sound/heat absorbing material out of there. if youre feeling ambitious, there is some behind the dash also, and check behind the interior panels aswell.

teamgn87 · 07-15-2006, 02:00 AM

I would take one of those sway bars.Does anyone know where I can get an aluminum core support?

T Spool · 07-15-2006, 03:16 AM

Seems like I saw one for sale on one of the boards just recently for $300 and I think the guy said he would not ship. They are never cheap and they are hard to find ones that aren't corroded where the radiator sits, at least that's what I hear.

T Spool · 07-15-2006, 03:27 AM

MonteC and teamgn87,

I will PM you guys as soon as I figure out shipping on the bars. I just don't want to take peoples $ until I am ready to ship! I have 3 of them and should have 4 on Monday. Thanks for your interest.

PLEASE BE CAREFUL WHEN PURCHASING AFTER MARKET EQUIPMENT. SOME PARTS MAY BE HEAVIER THEN OEM EQUIPMENT.
