Weight Reduction part 9

Rizzo314 03-13-2006 09:07 PM

[QUOTE=BIGSKYWRX]I wish I had taken some weights when I had my aluminum radiator in my sedan- it was larger capacity (37mm vs 22mm- AWR), but just going by memory I thought it weighed about the same as the stocker- the stocker was pretty light (plastic).

Is the C&R the same capacity as the oe one or larger?

SGD- thanks :)[/QUOTE]
I have no clue, I can try to find out.
BIGSKYWRX 03-13-2006 09:32 PM

Just thought os this too in relation to radiators- if it is a larger capapcity- the weight savings would be "outweighed" ;) by the additional coolant. Yes your adding to the capacity of the unit, but I haven't found the stock size radiator lacking at the track.

Sooo- does anyone make a stock size all aluminum radiator?
S.G.D 03-13-2006 10:49 PM

here is what i got for the bumper beams. keep in mind, these are close figures all measured in inches. they aren't exact, but they are very close.

this is a rear JDM/Light bumper beam for the ver 5/6 style bumper.

I
thought some of the JDM models didn't even use a rear bumper. Anyone?

San
BIGSKYWRX 03-14-2006 09:35 AM

SGD- thanks! Great detail! I'll see if it looks anything like the 02+ ones :)

San- the JDM v7+ didn't even run a rear beam I'm pretty sure (v8 didn't for sure).

I'd rather replace mine w/ a lightweight one vs full delete (if it's even possible). The GC lightweight rear beams can be had new for about $50 :)
oldmansan 03-14-2006 10:55 AM

Hey
BIGSKY, will the lightweight beam fit my 02 WRX sedan?

San
S.G.D 03-14-2006 10:59 AM

no problem, hopefully it helps you out.
BIGSKYWRX 03-14-2006 11:31 AM

San- the 02- 04 (maybe higher as well) all have he same rear beam (sedan/wagon/STi) 57711FE020, the older GC's a different part # 57760FA151.

What I was hoping is there is just minor differences and it would bolt up- hard tell ing though. The lightweigh rear beam (GC) weighs in onlly at ~ 7 lbs, the stocker is 28ish :)

Although in Japan the "new age" (there my01+) Impreza's run w/ no rear beam at all (lightweight up front).

The jdm version WRX weighs in at 90ish lbs lighter than it's usdm counterparts- I can account for ~ 43 lbs for the beams (or lack there of)- they also only run one cat (downpipe)- so there is probably 10-15 lbs additional there- where the other 30ish lbs is I don't know.
The Hit 03-15-2006 03:29 AM

Has anyone tried shortening the exhaust, like re-routing it to the sides ala JGTC? Maybe getting the muffler under the glove compartment? Sorry if this sounds crazy (refer to time of posting at left<<< :lol: )
BIGSKYWRX 03-15-2006 10:55 AM

SGD looking at the FSM it looks like the 02+ beams are at least similar- three bolts underneath/side (is that correct for your piece?). They also show one bolt above- does the GC have one bolt (located to the outer edge-at a 90 degree angle- coming right into the beam) used for mounting? If so any chnace you could take that measurement (hole to hole)?

TIA
S.G.D 03-15-2006 12:02 PM

are you looking at those little "foot plates" or the part with the 9 holes on top?

those little foot plates have three threaded holes that are bolted from underneath the car.

not sure about the 90deg bolt. can you point out on the image where you're thinking about?
Rizzo314 03-15-2006 12:05 PM

This picture confuses me.

1.75 + 2.5 = 4.25
2 + 2 = 4

S.G.D 03-15-2006 12:10 PM

haha, oups. probably a typo, but im not sure which.

i'll have to check that when i get home.

thanks for pointing that out :D

edit: its most probably 1.75 + 2.25 :p
BIGSKYWRX 03-15-2006 03:23 PM

SGD the GD/GG looks very similar w/ the holes that are mounted underneath (not sure on distances though), but in addition there two bolts that mount on each out end (near where you 4.6 written)- these mount directly from the rear of the bumper into the rear of the chassis (90 degrees from where the three bottom bolts go)
S.G.D 03-15-2006 04:17 PM

i think there are holes there, im not sure if they are threaded or not though.

i will take a couple more pics when i get home for you.

from front and back...hopefully this is what you were looking for. doesnt seem to have any holes where you described.
BIGSKYWRX 03-16-2006 08:06 AM

It's hard to describe :) The holes I'm talking about would be on the beam portion- slightly above the beam looking at from the rear, two bolts towards the outside of the beam-going directly into the chassis (vs coming from underneath like the other bolts).
Peeblesmx445 03-16-2006 02:40 PM

Anybody got a link to those people that make the aluminum trunk to rear seat seperating peice???
S.G.D 03-16-2006 04:19 PM

search for beatrush. they are the company that makes the piece.

there is a vendor on iclub that sells their stuff, Kamispeed i think.

bigsky: i'll take another look tonigt, but i dont think my bar has what you are talking about.
rst4me 03-16-2006 10:29 PM

wow lots of info.
does any one know just how much youd have to take out to notice a diffrence? I know my car seems to be sluggish with 2 other people in the car but when my g/f is in the car I dont notice a diffrence (140lbs).
I have been restoring a 73 charger and all the drag people are obsessed with weight reduction but so far no one has produced clear numbers 1/4mile times, that show the improvement. There have been some that have gone so far as to take a 1"dia hole drill and drilling out holes in the inner support metal trimming as much as 700lbs and still having a full intirror.
about the tar removel, fire extinguasher, scraper, and heat gun/torch and mind the wires!!
I think efforts that would yeald better results would be iliminating rotating/recypicating mass, flywheel, rims, pullies, rods, pistons, drive shafts, and maby even half shafts if some one makes em.

Wiper Motor and Horn
Forgive if already mentioned.

What about the removal of the wiper arms, wiper motors, wiper motor brackets? Removal of the windshield spray system?
Slap some Rain-X, every two weeks, on that JDM windshield I know you already have installed.

Remove the Horn.

way impratical as well. even with rain-x it will be nere impossible to see. Those reasons and you are not saving that much weight by doing that. You would save more weight by removing the abs system
rst4me 03-17-2006 01:09 PM

If your that worried about curb weight you might as well sink the RS-T money into N/A proformance bits.
The turbo housing alone is a heafty chunk of cast iron.
I understand that the power gain from the turbo will more than make up for the weight but a 300hp turbo car will weigh more than an identical 300hp N/A car..
rey_vibora 03-17-2006 08:17 PM

Change the stock subframe with the BEATRUSH Super Light Subframe to reduce 20 lbs. This is made of 7075 Aircraft Aluminum for great strength to weight ratio.

Funny some of the weights quoted for different items- the subframe sure gets misquoted often- Scotty's weight is spot on. I'm also quite fond of the highly exagerated quotes for under dash pieces/glove box/center console pieces :lol:

If you added up some of the weights quoted, we'd have cars that weigh in at about 700 lbs :D

Motorsports has a good thread (within the sticky) w/ some very accurate weights on oem and aftermarket bits.

Yea, I know. I have been surprised at how much some stuff has weighed though. After pulling my tar paper and sound deadening I was surprised to see it weigh in at about 15 pounds. I still have a little more tar to pull, so it will take a little more off.

I hate the people that say "Why do that, it's only like 1 or 2 pounds. Just don't eat and take a dump the day of your event." Well, those 1-2 pounds add up, and I don't want to have to not eat everyday.
BIGSKYWRX 03-18-2006 10:41 AM

20 lbs for the beatrush sounds more feasible- I've emailed them to see if they can actually put one on the scale. I can't tell form the pics but I'd like to see if the front under tray can still be bolted up- not a piece I want to give up.

The tar and sound deadening definitely add up- someone (quite awhile ago) posted up a pic of the plie he removed and then weighed.

yeah, but it would be lighter :D
that is if your goal is as light as you can get.
I admit it was kind a dig.. My thought on the whole subject is every little bid dosent help. Its just placebo power and your not going to see a diffrence. All thats going to happen is your going to end up gutting your car to the point were its unsafe and uncomfertible to drive on the street.
but Ill shut up about that because there is some great info on here...
BensonRST 03-18-2006 07:10 PM

[QUOTE=DoinkMobb]I would have left out the carpeting after scraping out the sound deadening, but the bare metal looks like ASS now. There's some plastic snap-on thingies that hold down some wires or something, and heating vents that go towards the back of the car.

I'm sure my GF would complain every time she got in the car too.[/QUOTE]

I can verify the fact that no carpet or sound deading meakes the girlfriend complain EVERY time they get in the car. Especially when you have an exhaust leak and it's blowing right in their face! :lol: :lol: :lol:
aspera 03-24-2006 02:02 AM

BIGSKYWRX,
Please see my thread about aluminum Corvette swaybar endlinks (as seen on the new Z07). It looks like these endlinks are;
1)Made in Japan
2)metric
3)aluminum
4)OEM
5)pirrow ball :D
6)cheap (less than $20 each)
7) just about a perfect match for your aluminum front control arms
8) at least half a gram lighter than the steel STi parts. :p
BIGSKYWRX 03-24-2006 09:34 AM

Interesting- has anyone tried a fit or have measurements? I'm sure I've got some old links around I could measure.

Got to love the "pirrow" ball design :)
N8WRX 03-24-2006 12:59 PM

Make sure the pervious owner of your car (if there was one) didnt have a INSANE stero system in his car.... for this happened to me and i found about 50lbs of unconnected wires and what not running thru my car, let me tell you that was a fun day trying to get it all out and i still think theres more in there!
aspera 04-06-2006 02:09 PM

I just got the aluminum Corvette endlinks.

OBSERVATIONS:
(1) cardboard box says 'Made in Japan'
(2) aluminum endlinks are clearly marked 'Made in Japan'. It is cast into the part. America's sports car???? :p
(3) Thread on the studs is M12x1.75. Pretty coarse. Big, too.
(4) No nuts included with endlinks. Why GM?
(5) Hex on the studs is 6mm.
(6) It looks like the length of the endlink (from center of stud to center of stud) is 80mm. That's a little longer than the Subaru part.
(7) It looks like distance from the centerline of the endlink to the mounting face is 20mm. That adds up to a 40mm distance (upper mounting face to lower mounting face). I don't know if that helps you wagon guys out or not.

I have no idea how much they weigh, but they are pretty cool.

So, what are the dimensions on the Subaru endlinks? I'm thinking they are M10x1.?? studs and about 50mm~60mm long.
S.G.D 04-06-2006 02:11 PM

got some photos?
BIGSKYWRX 04-06-2006 03:19 PM

oem sedan front links- 10mm studs, to use the GM ones you'd have to drill out the end of the sway bar (unless the holes are big enough to accept a 12mm????.

other dimensions- stud to stud length- 59mm, stud length 23mm, mounting face thickness 24mm (12mm from center each side)

I'm guessing they won't work w/ the GD sedan or GG, might work w/ the GC/GF's w/ aluminum arms- those links are about a inch longer.
aspera 04-06-2006 07:48 PM

Vette stud length is 30mm.

So, I'd have to ream all of the holes from 10mm to 12mm. The endlinks would be Z'd a little bit (8mm per side), unless I used a WRX wagon swaybar on my WRX sedan or something.

Are the rear STi 'pirrow ball endrinks' identical to the front ones?
BensonRST 04-06-2006 07:56 PM

[QUOTE=dust12]I would take this 1 step farther - Don't drive your car at all. Llet super models in bikinis drive it because they weigh less.:lol:[/QUOTE]

That's what ESX did with their car. find a 95 pound beautiful blonde girl, and teach her how to launch a car with launch control, then how to shift with an air shifter. problem solved. 100 lb weight reduction and instant fan base. :banana:

Actually the rear STi links are longer- so that might be a possible option- I don't have one to measure up though.

Interested in removing the front and rear bumper beams on my 04. Do the front and rear bumper covers rely on these beams to stay straight? Will I get any bumper sag?
BIGSKYWRX 04-16-2007 02:44 PM

the rear shouldn't as the jdm models come sans rear bumper beam- ie none

the front they get a lightened version- so I can't say for sure- I've had mine off several times and it appears it's not required as far as the bumper cover goes
deebee8 04-16-2007 03:35 PM

bumper beam
i believe the front bumper beam is required to hold the front bumper cover on....

correct me if im wrong,
BIGSKYWRX 04-16-2007 07:38 PM

it's possible it lends some shape to it- it's not directly attached to it

you can pick up the jdm front beam pretty reasonable- it shaves a nice 15 lbs off the front (12.2 lbs vs 27.6 lbs)

[quote=deebee8;17738517]i believe the front bumper beam is required to hold the front bumper cover on....

not true, I have mine removed and it looks just fine, no sag or anything. Just make sure you reattach the bumper correctly or it will sag....but not cuz of the bumper beam being gone. :)
deebee8 04-16-2007 09:27 PM

you guys are correct, it HELPS add shape, but isnt necessary to hold the bumper on..

i have a fmic with a new bumper beam anways
