Noob to weight reduction

[gst fat]

So the car is no longer a dd so here I go

It's a 2g fwd 4g63
Making 330whp and 290tq
More to come of course,
I wanna do weight reduction how much is actually capable of reducing in the car other than the hood trunk and sunroof? I know the rear seats don't weigh anything,If I'm correct the car weighs 2850 from factory and the awd weighs 3150, ac is completely out of the car, I will not remove power steering either so help me out

A lot of people remove the spare tire and jack and all of that in the trunk. You can also get CF doors and CF fenders. Also removing the glass and using a lightweight alternative will shave a a lot of weight, that is also an option, but a bit extreme.

And I know about the trunk glass as well

the only other thing i can think of is gut the interior.

Exactly but where do I start?

 

[greenydsm]

take the rear seats out, relocate the battery to the back with a smaller lightweight battery. Get light weight racing seats. Take the crash bumpers off. Gut all the emissions.

Thats a start. Have fun

 

[Bluefire16]

Rims as well, get some lightweight racing rims. CF hatch/hood, and take out all seats except driver and swap it for a lighter one. Like the very thin metal ones that hurt like shit, but weigh like 5 pounds.

Thats how to lighten the car.

Don't forget to remove all panels and the dashboard, lightweight doors, and maybe a foam-filled interior.

My rule of thumb of weight reduction.

There's nothing that weights 1,000lbs, but there's 1,000 things that weight a pound. Good luck and enjoy.

The tar/sound dampening stuff will save you a few lbs. The factory has it sprayed all underneath the carpet. Road noise will go up, but I'm guessing your not worried about that.

Ive heard two ways to remove it and both don't sound like any fun. One is with heat, then scrape it off. Sounds pretty messy.

The other (which I would chose) is get some dry ice and crack it off. I'm sure there is another thread on here that goes into detail.

Thanks yeah I heard about the dry ice way, I heard that stuff is pretty heavy, and thanks to everyones input

Something that a lot of people look over is rotating mass. This actually weighs more than stationary mass.

A friend of mine used the dry ice method in his 240sx and it worked well. The ride was so much louder afterwards though but I'm guessing you wouldn't mine that.

You'll see the biggest gains with lightening rotating mass. Lightweight wheels and tires are usually the best place to start.

I heard this was a rule of thumb for weight reduction, not sure if true. But still, I agree with rotational mass making the biggest difference.

100lbs of stationary mass = about one tenth quicker in the 1/4 mile and one MPH quicker.

10lbs of rotational mass = about one tenth quicker in the 1/4 mile and one MPH quicker.

 

[motozachl]

Light weight rotors would also reduce some rotating mass. Also if your going extreme take out the speakers/radio, heater core and all vents, air bag system components, antenna, windshield wipers etc. Basically remove anything that doesn't have to do with the actual cars function of moving/running.

 

[Oliver@Slowboy]

Small battery kit
Lighter wheels and tires
Pull all interior out, make aluminum door panels, use lighter seats
Remove wing
Remove bumper crash bars (if you are not driving on the street)
Replace gas tank with fuel cell
CF hood/hatch/doors
Speed glass
Lighter brakes
Remove heat shields/emissions/ect.
Remove fog lights/any unneeded stuff like that

The list goes on, be sure if you are planning on driving this on the street at all you don't remove anything that will compromise the safety of the car or remove anything that will make it illegal for use on a public road.

Another option is to replace the wheel hubs with billet ones.
like this one

Quote from the website so you don't need to see the pics.
"Machined out of 6061 aluminum and billet steel, This is our own custom billet wheel hub for the 2g DSM. These are for serious racers only and require that you fabricate upper and lower control arms. These are built to accept the stock wheel bearing from a 2G or EVO by converting to these you will be able to save over 75 lbs per corner on your 2G DSM. They are reversible and modular. The steering arm is made from steel to handle the high torsional stress loads and the opposite side can accept the bracket for the type of brake caliper that you run. By utilizing these hubs on your car you will save over 150 hp in unsprung weight on the front end and 150 lbs total weight. Think about it"

Basically, it all comes down to how fast you truly want to go and how much you want to spend on it.
A stroker, racing tranny with dogs, full port and polish, etc.
My suggestion is to figure out a budget and what you can work with before you end up at home eating kraft dinner knockoffs and watching the same reruns over and over again.

Wow, those billet wheel hubs are awesome!

Seriously! I wonder how much they are. And I'm really surprised they don't make one for 1g's.

 

[Chicken Patty]

I wonder what the price is, maybe we should give Magnus a call
I would've imagined them being for 1g's more than 2g's

 

[habitatguy187]

Same here since there's more 1g guys putting down big power than there are 2g's. I bet they would make them for a similar price.

 

[Chicken Patty]

I'm sure, I am also sure it would become popular for the big boys!

Yes, I agree with that.
