Ok some people have confused lightweight pulleys, with underdrive pulleys. Lightweight ones are the same size as stock, just lighter. Underdrive pulleys are smaller than stock. Neither ADD horsepower, but they do Free Up horsepower (i.e. rotational mass) Underdrive while freeing up more power, sacrifices the pulleys on the Alt, Water, and A/C. Removing weight from a moving part has a much bigger effect than weight from a static part. Example - Bowling balls, while same size, different weights, much different effects. Energy is spent turning a pulley, the energy comes from the same place that turns the flywheel/transmission/ shafts etc.. So a lighter pulley/ flywheel driveshaft means less energy needed to turn them and more for the wheels. Thats why theres a difference between crank HP, flywheel HP, and the HP read by the dyno. Its called parasitic loss and is incredibly effective. The factory puts the heavy crap on there to do their best to make the car last, so they sacrifice power.

Aluminum driveshafts are a third of the price and only 1 lb more than the carbon fiber ones.

Braille batteries are a waste of money. They are literally DEKA batteries with a different label. Save $70 and buy Deka.

For the 03 WRX I have seen that Seibon has everything except the rear fenders in CF, I'm planning on that eventually, should drop an assload of weight.

Don't forget to factor in all the piping weights. Stock is cast iron, Stainless Steel is much much lighter.

Port and Polishing (especially the TGV delete) does remove some weight, for some people its negligible, but others want every ounce they can.

Ceramic Coats vs Exhaust Wrap. weight considerations there.

Fluid is friggin HEAVY! Run low washer fluid, STi guys run low IC spray fluid. Dont bother running low on brake/tranny fluids - dangers outweigh (no pun intended) the gains.

Lexan is awesome, it is clearer than glass offering more light, expensive as hell, scratches very easily so get it coated, and is illegal for road use (wont break if you cant open a door in an accident). So I could see doin the rear windshield and thats it. Plexiglass, again expensive, dangerous, not street legal. But yes light as hell and I want money to do it.

Consider the reverse manifold for you FMIC guys - less IC piping needed.

Replace brackets/clamps/excess bolts etc with zip ties if possible. Itll add up

Wait until you are done with losing weight before buying springs. (or get adjustable coilovers) If you drop enough weight, the car will ride higher! now the CG is up where you dont want it so youll need to drop the car back down.

Careful removing the front Brake Shields (not saying dont, just be careful). The heat can mess with the lines/sensors/etc.. It is also a heat sink.

New steering wheel

Remove excess electronics, any light being on (even an OFF light) is drawing power, meaning more work for the alternator. it all comes from the batt to start, the alt just fills it back up.

Custom trim- there is always someone who can make something. Lightweight dash, consoles, etc...

Shorten up hoses, reroute em if you can.

And finally, yes you can add horsepower to go as fast. But going lighter, will, as mentioned before, makes the car brake faster, handle better, get better MPG, accelerate faster, make your engine last longer, and make any mods you add to it (turbo, headers, etc) have a much bigger effect. So, while saving up for parts or while ur installing something, remove extra stuff here and there. Talk to other people who have a light flywheel and light crank pulley, they (we) say "It's like going from stage 1 to stage 2 all over again." Thats just 2 things, grand total of $570 plus shipping.

Lightening the car makes the engine work less to produce the same effect. It's that simple

I just installed a DSS driveshaft and omfg what a difference. It feels like I could knock off almost .5 sec off my 1/4 time. Upshifting, downshifting, accelerating is much faster. I also have a lwcp and fw. The only drawback is vibration at certain speeds but overall its a way smoother drivetrain. Also the rear crossmember needs to be notched to allow clearance especially during downshifting. One of the best mods ever imo.

:lol:

A 35W bulb takes .07hp to light. I stripped my car of excess wiring and creature comforts for the weight, but worrying about leaving your stereo on standyby because it's making your alternator work harder is kinda silly.

Even if your alternator was working at max capacity, accounting for inefficiency it's never going to draw more than 3hp. With everything turned on, it's designed to be running at half capacity, so around 1.5hp. That's all your heaters, lights, stereo, everything.

I run a miata battery rather than one of the lightweight racing batteries. I feel they're more reliable, especially on a built car that might stall and be hard starting compared to a stocker.

ACPT carbon fiber driveshaft = 16 lbs (03/2004-2007)
[URL]http://www.rallysportdirect.com/ACPT-Carbon-Fiber-Driveshaft-Subaru-STI-2004-2007[/URL]

DSS aluminum driveshaft = 12.6 lb (03-07)
[URL]http://www.swiftmotorsports.com/product_info.php?cPath=978_979_1010_1227&products_id=1275&osCsid=58vq3befvgp3tipgsnphoimrf1[/URL]

However, The aluminum one does require modification to the underbody, for it to fit. Not sure on the CF one.


As for the bar under the rear seat, from other stuff I've read. It does not appear to do much stiffening as it attaches to the floor pan and not the chassis. It does provide support for the people sitting there. For those that do notice a difference in handling without it, try some sway bars, strut tower bars, or even the strut tower triangle that Oswald performance has. Oughta tighten it right up.

As for other stiffness, there is a foam that is injected into areas and then it hardens thereby stiffening the chassis up, yes it adds weight but as a replacement for a heavier piece it could assist in dropping some weight while adding safety and keeping the handling. Handi-foam for pillars comes in injectable kits - easy to use. For the bigger parts US Composites makes "Urethane Pour Foam" works very well.

stidoc 11-04-2010 06:05 AM

^^^Let me correct you again. The ACPT CF driveshaft weighs 14.5 lbs which is 10 lbs less than the stock driveshaft. You must also remove the driveshaft protection plate with the ACPT DS which saves you another 4 lbs + about 1 lb for all the bolts not reused. I bought the ACPT ds because at the time The DSS aluminum pieces were having quality control issues. The ACPT, if installed correctly does not require any modification to the car. I have no idea what the aluminum DS weighs.

Otherwise you've given a fair sysnopsis of Anorexic and A-man's journals from IWSTI.
b3delta 11-04-2010 06:32 AM

Well then someone better inform rallysportdirect.com that they have placed the wrong weight on the ACPT CF DS.

Either way, they are very close to each other, so it's personal preference as to which DS one would buy

Love their journals, the Anorexic and A-man are legends

I'd like to get it down to 2600 as thats the minimum for my class in autocross, but I dont see how I can find another 100lbs without gutting the interior, getting 1 piece buckets and getting lighter wheels and brakes, and it's just not in the budget or the spirit of the car.

Mine has the lighest possible brakes, one pots and drums. But I have heavy steel wheels. I've been back and forth about putting lighter wheels on it. I kinda like how stock it looks now. I had a lighter TBE on it, but it was too loud so I picked up some weight there.

Obvoiusly this isn't a road course or autocross car, I use it for general driving around and drag racing, so I don't need a lot of braking power.

I'd do whatever to it to get it lighter as long as it looks stock on the outside.

I'll probably do the door beams soon. I think I've figured out how to extract them without trashing the doors and having to paint them.
68Cadillac 01-02-2011 01:57 PM

Finally got around to installing 250 in/lb springs on my Ohlins Height Adjustable Struts. I used them for autocross but I dont' do that anymore and driving around on 400 in/lbs (F/R) springs was jarring. So with those installed I lost more weight. This is the fourth time I've installed those bastards. Getting faster at it and the process of aligning the car in the driveway.

Instead of removing under seat bar all together use a cheap strut bar to replace some of the metal with lighter aluminum. Provides stiffness and seat support like oem bar but it most likely useless in crash protection,

soo many pages with good info, i am on my second wrx, a 2011 limited, SPt SS, trunk liner and a few other factory add ons. i have been thinking of doing some light weight mods, here are my thoughts. . . . .

removal of front and rear bumper beams, i figured if thats the only thing saving me in a life or death accident i was meant to be dead.

removal of entire spare and other tools including foam pieces, carpeted cover, everything!!!

CF hood
CF trunk with limited wing
LW deka battery
SS headers and up pipe
SS catless tbe

any thoughts? i want to get the car down to 3100 pounds with with me in the car and a 1/4-1/2 a tank of E85 :) i figure by dropping 200 pounds there is some good gains to have, btw is losing 200 pounds worth anything on the car, like for every 1 pound loss you gain XXX type deal????

any thoughts? i want to get the car down to 3100 pounds with with me in the car and a 1/4-1/2 a tank of E85 :) i figure by dropping 200 pounds there is some good gains to have, btw is losing 200 pounds worth anything on the car, like for every 1 pound loss you gain XXX type deal????


thanks[/quote]

That's basically what I've done or am in the process of. if you want more details PM me.

But in short, I'm sitting at 3090 lbs, so I'd say about 3150 with a full tank, more or less. I've dropped about 210 lbs so far and that alone has shown me a huge difference. I'm still going, only thing carbon on/in the car right now are my seats. I'm aiming for 2960 lbs (full tank of gas, without me in the car), or 400 lbs under stock weight.

EDIT: Oh and I believe it's every 10 lbs is about 1 HP. but you also have to take into consideration that now your car is at less mass than before so it will move forward faster than before... make sense... but what I'm saying is, it feels like alot more than just that supposed "added HP".

well seeing how you have an STI im sure i would be sitting alot lighter than that, but i cant wait to get that extra weight off, see the after affect.

Just about going in there and tearing it all down. Mostly just time consuming, I've never done it, since mine is a DD; but I've taken my interior apart to where everything was out of the car. It didn't seem too complicated to pull the air bag system out. Just make sure you disconnect the battery.
