Weight Reduction - Page 6

How do you take out the rear center seatbelt? The reel part has a bolt under that carpet on the back, and I can't figure out how to take that carpet out.

Also, anything good to plug up those holes left from the child seat hooks?

pull up... hard

actually I used pliers to squeeze the clips together from underneath and then pulled up

bemani · 04-04-2003, 08:17 PM

Do you have to take out the cabin stop light first? Because I can't figure out how that goes either.

ellisnc · 04-04-2003, 09:37 PM

yeah it unbolts from underneath if I remember right

come on man get creative

Soon2Bgreat · 04-05-2003, 06:36 PM

so did anyone figure out how much the AC truly weighs?

QAboy · 04-05-2003, 11:09 PM

i'll try and remember to weigh it when i go home tomorrow

DoinkMobb · 04-06-2003, 12:49 AM

The rear seat cushions and seat belt mechanisms are next of my list of things to rip out, but I can't quite bring myself to do it.

I mean, if I wanted a 2-seater I would've bought an MR2 or a Miata. Then again, I drive the car alone 95% of the time and the only other passenger I ever have is my GF. Plus I'd be saving about 35 lbs (or so I've heard), which should bring me down to 2300 lbs.

I was thinking of getting some kind of material to cover up the bare metal and the hole to the trunk after the seats are taken out. I'm not sure I'd like to see exposed metal and wires in the back of my car.

I realize this is speculation, but my guess is about 35 pounds for everything... maybe 40

How much money ya got?

Carbon parts are available to "finish" the rear seat, seat back, and parcel shelf. Footwells and door cards are also made.

I didn't even know parts like that existed. I bet they cost A LOT too.
I was thinking of getting some 1/4" black foam-like material - something I could cut to cover the shape of the back seat area. If you've ever removed the rear bottom seat cushion, there's some material like this covering some wires or something.

Before I rip everything out, I want to make sure I can cover it up again.

bemani · 04-07-2003, 01:22 AM

Anyone have primitive's light weight trunklid?

And if you have a fog cover, you can basically drummel out all the stuff on the bumper that used to hold the fog light. (Or, anything that the cover covers up

)

*went to U-WRENCH-IT today...COLD!
*found shelter in a Legacy...decided to dissect side mirror

*found out that while the shell is plastic, the base is all metal
*found out that the adjuster was lightweight
*realized that I was a strange human because I was doing this

This seems like a pretty good place to save weight. Carbon mirrors look great and surely weigh less. They might also reduce drag, clear raindrops, and be quieter. The weight savings is in a good place (high and forward).

The only downsides are functionality and cost (mostly cost).

ellisnc · 04-08-2003, 07:08 PM

Just in case you guys that are into saving weight on your car haven't really felt the results

I had mine on the track this weekend - one word - amazing

Awesome amounts of grip and changes direction at will

My instructor who was driving a more or less stock WRX was quite impressed and said the car was very nice to drive after taking the wheel in mine. Another instructor who was driving a Z06 said "this car flies" after just riding in the car. I pushed a very well driven C5 very hard in the corners so he had to let me by on the straight.

anyway, it's ALL worth it

I'll post more results from the PCA event in May at Mid Ohio... hopefully there'll be some more humbling going on

WR xplosive · 04-09-2003, 12:15 AM

I didnt even know that the TEIN SS coil-over are actually lighter than OEM shocks and struts. TEIN SS weighs 73lbs while in the packaging that includes the wrenches. OEM weighs aprrox. 100lbs

by doing this, I already reduced the weight while having the benefits of the coil-over

Actually, according to rhr performance, the rear seat cushion and back are 550 total. Not that bad for 22lbs of weight savings. They cost less than a pair of CF mirrors.

Honda dudes can get Speedglass (polycarbonate) windshields for less than $500. Jeep guys only pay a little over $300.

If the price was lower, I guess you could just replace it if and when it got too scratched up. A rear window would be more streetable, though.

How much would you guys pay for a scratch resistant smoked polycarbonate rear window?

we could just order the STi rear glass when that car comes out...

tifosi77 · 04-11-2003, 12:51 AM

I just happened upon this thread and I thought that I should through my .02 in on this, The WRX is a really nose heavy car and I have done just about every weight saving thing that can be done, but by far the biggest difference was removing al the pieces of the A/C the front of the car feels lighter and the engine seems to rev a little easier (I am not really a butt dyno guy but this actually shocked me) probaly 40lbs, carpet 5-10lbs, all seats and airbages (at least 100lbs), sound deaedining and sealer on the floor pan (this was probably 40lbs), lighter weight brembos, forged colks (14.5lbs each less tires) head liner and door cards, speakers, radio, stock steering wheel, all trunk trim, all interior trim. I am going to weigh my car and let people know how much lighter than stock. The doenside is my car is really really loud, this car is going to seam welded and caged so for mee it is no big deal. For other type of weight loss you will get that from composite door panels, false floors (Carbon Fiber), front seats, rims, and brakes. If anyone needs composites for their WRX let me know I can supply wuite a few things.

aspera · 04-11-2003, 01:08 AM

How much did the headliner weigh? It couldn't have been much.

ellisnc · 04-11-2003, 05:44 AM

hey tifosi

if you're going all the way with the car and when you have it seam welded and take all the electrical harnesses out of the car you should remove the unnecessary circuits from them. Wire can add up!

ellisnc · 04-11-2003, 05:45 AM

also I think I may have found something else that we could remove.

in the trunk are there is a silver box that looks like an audio amplifier tucked up under the wheelhouse on the right hand side

can anyone confirm what this unit is?

Quick WRX · 04-12-2003, 01:25 AM

This may be stupid, I havent really looked at the rear brakes, but what about removing the backing plate on the rears. Also I have seen race preaped cars with sections of the engine bay walls and floors removed. Just a thought.

If we're talking about the same thing (the box before bumper w/couple rubber hoses?), as per Dave of Rallispec, it's a "emission-control" unit. Not sure how essential it is though.

no no... this is inside the trunk... it's machined aluminum with what looks like heat sinks on it
