OVER 200 LBS. IN WEIGHT SAVING IDEAS

[Col. Brain]

it was asked "how extreme?"

Carbon fiber lift off hood
carbon fiber fenders
carbon fiber trunk

remove all seats - install light weight driver seat
remove everything inside the doors (i do believe there is some sort of crash bar in there)

lighter wheels can be had

removal of heater core/radio/dash in general

Ti exhaust

You could probably take a few hundred pounds out of the car easily. Now do you want to take those pounds out?

From 505hp and 3800lbs to 625hp and 3500lbs could be achieved without much effort.

How much that will throw off the balance of the car etc remains to be seen (im a drag racer at heart - weight is weight to me )

[McRat]

The only difference with weight in the twisties vs. drag, is that a heavy car set up right can pull as many g's in a corner as a lighter car can. In a drag race, always bet on power-to-weight, and remove weight from the nose back.

Obviously the Z/28 has already proved that.

Three areas to concentrate at would be wheels-tires (simply because 1lb acts like more), corner weight reduction improves turn in and can increase g's, and high weight to lower the CG.

Lightweight clutch and flywheel, aluminum or Ti lugnuts. Don't know anything about the weight of the DSSV dampers but I think I saved 4-5 lbs per corner with my coilovers , Pfadt gen 1s, gen 2s are even lighter. Real racing seats.

[2cnd chance]

The washer bottle and engine covers are good for close to 15 lbs. coming right off the front.

[Angrybird 12]

How about removing the wiper arms, rods and motor? That has to be a few pounds.

Gosh dang, you guys are a lot more aggressive than Id imagine.

Here a fairly simple receipt for approx 150 drop. Lets call this stage 1.

1. Battery: 30 lbs
2. Headers and exhuast: 30 lbs
3. CF drive shaft and clutch: 25 lbs
4. Tubular front and rear crash bars: 24 lbs.
5. Rear seat delete.Not sure how much the Z/28 weighs but the standard seats weigh: 38.2
6. Rear seat belts: 3.6

My buddy Kevin (Owner of HM Racing and Design specializing in trophy trucks) made for us our crash bars. We had a bunch of guys wanting us to get some made for them. So we talked Kevin ino to making some more. Perhaps if you guys are interested. I can get him to make another batch. Here is a link to the original GB. http://www.camaro5.com/forums/showthread.php?t=334636


I will post a stage two but let me know if theres something that might still be considered stage one. Or is we should subract anything from stage one and make it part of stage two.

....Maybe for 1 also...

Window washer bottle....(at least empty it)...
Engine cover...
Under hood insulation....(if it has any)
Hood vent/heat extractor rain drain....(if removable)....

Floor mats!!

Interesting thread on the crash bars, thank you for linking that. Is there a solution to avoid Dremeling that rear bumper cover in a succeeding iteration? Any thought to perhaps welding in a threaded bung to both bars where you could attach a RennLine folding tow hook? Kill two birds with one stone. It'll bump the price of course but offer an elegant solution to the tow hook problem.

Is there a thread or link to a good solution for a lightweight clutch? Are we talking LW, single-mass flywheel as well? And if so do the worms come out of the can in regards to torsional vibration issues with the crank/dampener/pulley(s)? Just thinking out loud here. I already have plenty of worm experience and prefer to avoid earning more

I like the way your thinking on this one. The crash bars alone wouldn't make me jump, but if it solves the towing issue then I'm in...

Nathan, i think you should add something similar to the G5 Carbon line-up goodies!

[joeyrotorhead]

Nathan can you give us weight comparisons / savings for the following:

Dry Carbon fiber trunk
Dry Carbon fiber roof
Dry Carbon fiber hood
Dry Carbon fiber fenders


...sorry if i missed these in another thread

You cant remove crash bars, Theyreusually glued in as well as spot welded. Usually glued into the door skin.

You could lessen the weight by stripping the windows out and save about 8-10 lbs if you were strictly tracking it. Just wouldnt be ideal for rainy weather track days lol. If you wanted to lighten the load of this car to purely track it, I think you could get rid of at least 100lbs. Thats not even having to think about what to strip. If you stripped out and replaced with lighter parts as well as deletes, Id imagine you could get close to 200lbs stripped if not more fairly easy.

Give me the keys. I take it away. You have 0 lbs to worry about.
