Nope, already at the wire guy and we talked about it. I had the right one bookmarked, then they changed their site structure a bit and I had to re-find it. May see about swapping it, running it on a separate circuit, we shall see.

Not sure how you're going to make it work though. A DC transformer? Seems like it'd kill of any weight savings had from it.

Not to confuse anyone, I have a few cars. This is going into my fully caged rally car to test, as I build my coupe sti swap.

The swap will of course be on a diet. The rally car can only be on so much of a diet, I have to add so much.

So I just posted this for others to see.

I am going to ask them about a return, but being across the pond, I may just wire it separately.

Brian at iWire is doing the work, lucky for me, he is 35 miles away. I visit him all the time haha

This time I should do better. Not my video, but my car.

Racing was fun , the local track here runs only a 520 foot drag strip so I have no idea how to turn the et's and MPH into usable data that is relatable to a full 1/8 mile ( 660 feet ) or a 1/4 mile . For reference my fastest was a 7.125 @ 75.51 mph. 60' 2.006 (horrible but fun ) . I played around with the accessports launch control, it was tricky . The start is not flat so you have to hold the car with the ebrake.
But coolest part of the day was I got to race a R33 GTS-T , so fun I edged him out at the end . But really ever since the 90's playing Gran Turismo 1 I have liked those cars and just seeing it and getting a chance to race it was way cool for me.

I have done a lot to my car since my last post in here.

To start off I have removed the ABS system and brake booster and converted the standard brake pedal to dual master with balance bar.





I have also fitted a hydraulic handbrake and removed the entire cable system.



I have removed all airbags and controller. Removed the entire A/C system including all the pipes under the dash, vents etc. and cruise control.

I did not weigh what went back in but everything that came out was around 50kg. I estimate the car to weigh around 1210kg now.

pics of the doors, I kept the front rails to keep the glass in place with less work needed to make that happen. There are brackets to hold the windows down if I want/need to bring them down due to heat.

I was also given a bag of beautiful aluminum bolts from MSI, to do with what ever I wanted.

Well I feel I have rung the last of the water out of the towel on my '04 without going into full gut mode. Here is where it ended up:


Lf: 860 Rf: 854
Lr: 634 Rr: 624

This is all with driver (200lbs) and fuel for a total of 2,972lbs driving down the street.

Now lose 90lbs

To get even more weight out, you will have to look at removing tar from the interior, or maybe getting an aluminum deck lid...

I am in the same boat with my 05 wrx wagon if you have any suggestions for that. My hood is paper light. How much would a carbon fiber really drop?

If I'm not mistaken, you already have a stock aluminum hood. The "fake" carbon hoods that are very stiff and fit nice are actually mostly fiberglas with a layer of carbon for looks and are much heavier than what you have. An all carbon hood will be very expensive, somewhat flimsey and might be the same as what you have, maybe a little lighter. You'd want to know the weight ahead of time.

^ this. Do not buy a 'carbon' hood.

They are cheesy, do not fit right, break easier, lots of prep work to paint so the paint will not bubble, or if you leave plain, the clear coat comes off in a year unless you add more and polish monthly, oh and as said, they weigh MORE.


F that. Been there done that too.

Maybe 02-03 for you up there. I believe ours were steel... could be wrong.

04-07 for sure is alum.

While I do agree most are just as heavy as the aluminum hoods, there is more than just that reason to swap. Also the custom full CF ones used on time attack cars are extremely light, flimsy and dont have a great top finish but at that point you arnt looking for scene points.

reason I went to a CF hood (and it weighs less) is because of proper venting and a cleaner look than cutting and adding louvers. It also fits without issues.

Until you hit something, even as small as a curb while parked, and you bumper flexes up and cracks your hood.


Ask me how I know. -_-

All US WRX/STi hoods were aluminum from 02-07, the non-turbo 2.5RS/2.5i hoods were steel.

they went to steel for turbo cars for the GR. Not sure about the VA.

The GC cars are more tricky, US cars got steel and JDM cars got AL.

Subaru did not make steel and aluminum GD hoods, its was onl alum. They did not do what they did with the GC's.

Also a GC alum. hood is 15 lbs bare with nothing on it.
A GC hood in fiberglass with carbon on top is 17lbs bare. (This is not full carbon)

Sorry, but the GD 2.5RS hoods (without hood scoops) were steel.

Well my friends 2005 2.5i and my girl's 2007 2.5i both have scoop-less aluminum factory hoods. Strange. Not even magnetic!

Back on topic.

It Better

Default

For some comparison, I had a BOE carbon fibre roof for my Elise. It weighed 5 pounds and cost me $1000. It made sense because factory tops used cost $1000 and are difficult to find in the same color as the car.

When I ran my 87 CRX roadrace car, I built an all aluminum hood. It was held in place with 5 hood pins, and weighed 5 pounds. Although it had stiffening ribs riveted to the bottom side, it was far from stiff and would move around a good amount while driving on the track. But that didn't matter to me because racecar. I used swimming pool pieces left from an old above ground pool. Zero cost and 10 pounds saved on the car. Just sweat equity and a bunch of aluminum rivets.

not sure, I scrapped it and started over again with a cleaner (no rust) and lighter cage.

with that I just cut the roof off of this one to install the CF roof. Still need to do the doors. The ABS will be deleted this time and using a Tilton pedal box. Also doing a motorsport milspec harness for the car.
