Making the STI Lighter??
�
�
Besides obvious things to delete from the intended chassis of the subaru?
What are some of the mods to make the sucker lighter? I mean damn 3350lb curb weight is alot for a track car that most people strive to create?
Thanks

what up,eric? i'd say a titanium exhaust. it's like 10lbs lighter than your conventional exhaust. lexan windows? :eek:
| BoostdBoxer | 10-30-2005 03:28 AM |
Lexan yeah I thought about that.. not sure where the best place to get em though?
| S4toSTI | 10-30-2005 09:49 AM |
I don't know where this was seen or where to find this but i saw that they tried to strip a sti and they only got about 300-400 pounds out of it. You gotta remember you are gonna be adding weight back in... cage seats helmet fire supression.
| BoostdBoxer | 10-30-2005 11:08 AM |
guess the car is just plagued to be heavy. I am sure there are some things that can be taken off to make things lighter.
| STi-MAN | 10-30-2005 11:30 AM |
just think of lighter replacement parts, aluminium body coilovers, CF seats or carbon kevlar seats(i hear the stock sti air bag equiped seats are quite heavy). titanium or thin walled exhaust, and changing from the stock header will yield arounds.
| Evil STI | 10-30-2005 11:38 AM |
I dropped 40lbs just by swapping in a Braille battery and Magnaflow titanium exhaust. I'm swapping/deleting more parts over the winter that will allow my STI to be another 150lbs or so lighter.
| STi-JDM | 10-30-2005 01:52 PM |
take off the A/C, change the seats, throw everything out from the trunk, ti exhaust... I'll do these things to my car later on... :D
| SupraScooby | 10-30-2005 02:00 PM |
you could also get a lighter subframe underneath
| wgknestrick | 10-30-2005 02:11 PM |
Exhaust manifold: 10lbs
Seats: 50lbs
Front Subframe removal: 40lbs
Catless exhaust
Lightweight battery
Lightweight rotors
Front crash beam : 30lbs
spare tire/jack removal
Alum rear suspension links/members
These are just some mods you can do while still retaining some drivability. Try to get dual purpose mods, like the exhaust/manifold/rotors first then focus on the fres ones. You can keep chipping away at the weight.
Lossing 100lbs can be easy, 200 difficult, 3-400 taxing & $$.
With the heavy tranny and diffs, I don't think there is much more you can strip from our cars without going to a tube frame.
Cars are getting rediculously heavy these days having to survive crashes with SUVs (that shouldn't even be on the road)

| V5-STi | 10-30-2005 05:12 PM |
I think that you can save some weight by changing the factory brake discs as well.
The front calipers themeselves are also quite heavy.....!!

one of the most pain in the butt, but effective way is simply buying aluminum or lightweight bolts and replacing all of 'em in ur car.

150 without loosing daily driving abilities
�
�
I've gone down this path with a 996 porsche coupe (290+ lbs while keeping everything intact), a 2003 wrx (180 lbs) and most recent a 05 STi which by the end I want to be ~200 lbs lighter. It's always expensive to do IF your going to have it as a daily driver or street car that see's the track. I noted someone above sugesting weights. One things I've done every time I do a mod is weigh the car and weigh the parts coming off. Lexan replacements for glass is HORRIBLE idea. If it's a pure race car ok, but otherwise it's aweful. IT does save some decent weight, but it's horrible. It's impossible to see through, cleans terrible and the light shears off it completely unlike glass. You end up blind too often to be comfortable. A boxster (986) did this and it felt like a death trap driving in hollywood.
My sugestions are -
SEATS - this is the easiest and one of the best mods you can make. A 1 piece bucket seat will be superior to the STi seats, put you about 2"-3"s lower in the seat and SHOULD save you no less than 80 lbs if you do both fronts. If all your going to save is 50 lbs by doing the seats your buying the wrong seats. Recaro seems to make the best affordable bucket seats. In my expirience (which is limited) the sparco stuff is just as light BUT the actual hardware to install is generally heavier AND on the two cars I've installed evo sparco seats on the height changed was very limited. No expirence with bride, the gody labeling is way to much for me. On a 996 porsche I saved 65 lbs PER seat by going recaro.
Aluminum or titanium hats. 7.5 lbs per front is my current savings and ~13 lbs per rear. Now this is of course the best place to loose weight on a car, but regardless my car weighed 43 lbs lighter post brake rotor/hat swap.
Turbo back - My muffler, midpipe and downpipe exchange (which still has a cat). downpipe was 8 lbs lighter, the midpipe was 13 lbs lighter and the muffler itself was ~11 lbs lighter. ~ 32 lbs of weight, plus hp.
Wheels and tires - STi wheels are light, tires are not. But regardless no real weight to be saved here regardless of what you do. First time I've owned a car where that was true.
Coilovers. My fronts are about 7.5 lbs lighter and the rears are 9lbs lighter per side. 32 lbs of weight are the corners (zeals v6).
Battery is next step for me as well.. But so far we are talking about 190-200 lbs of things that are almost necessary for a track worthy car. Carbon Fiber trunk and delete of the STi wing for the c-spec wing is another 25+ lbs from what I'm told (going down that route myself). Now we are in the 220-230lbs range..
Keep in mind on a 3000 lbs car every 7.5 lbs shed is effectively adding 1 hp to the car.. Plus better braking and control.
It's also worth noting my car with about a full tank weighed a 110 lbs lighter than your stated 3350. The scales I'm using were only accurate to levels of 5 lbs, but when I got back in the car it got my weight extremely close (178 it said 180).

wowsers that is alot but at the same time isnt. I dont like buckets but damn they are light. Maybe if I had the extra money I could get buckets for the track and nice sparco seats for the streets.

Okay, some of the most important weight reductions you can do, imho are:
Braille Battery
Full Exhaust
Brakes (rotors)
Carbon Fiber Driveshaft (which is actually not frowned upon by dealerships because they are more safe)
Also, if you're overweight, go on a diet ;)
Carbon Fiber trunk (thats what I did)
this might be of help to you too!

you can upgrade to a billet 6 pot or even a billet 4 pot and get some light weight rotors.
a good company to contact about amazing brake products that save 8lbs on the front rotors alone is

how bout a JDM front bumber bar??? plus the BBS wheels are heavy ass hell
| the_colombian | 10-31-2005 11:36 AM |
Forget the weight loss Eric, just get the bigger hotside!
I would start by taking out that sub you have in the trunk and taking everything else out too. Then you can take out the back seat and passenger for track days. The wing weighs over 20 lbs. When I swaped my trunk, I took my wingless trunk off myself but I had to have help to safely remove and replace the wingged trunk. That thing is heavy!
You already got the battery and the bumper beems are a good weight loss but its also part of your safety so that part is up to you. A/C weighs a lot and the air filter box behind the glove box is unnecessary weight too.
Radio, speakers, unnecessary wires, More PT till you weigh 150 lbs hahaha. im kidding. thats all that comes to mind.

The BBS wheels are not heavy at all, it's the stock Bridgestones that are heavy. I think the 04 wheels are 17 lbs and the 05s are 18lbs...but correct me if I'm wrong.

You are right on. Stock BBS for MY04 is 16.5 and for MY05 is 17. As far as weight goes, that's very, very hard to beat without buying 2G+ forged wheels. That's why I'm keeping my stock BBS wheels and using them for winter....

You're right...it is the bridgestones that are heavy. Great tires, but still heavy.
Do a search in the motorsports forum, there are a couple threads on the weight subject.

I totally took off my brakes and saved 100lbs!!!

:rolleyes:
You guys must be ****ing oracles to feel a 1-3% loss in total weight.

Depends on where the weight is coming from bro, ever heard of sprung and unsprung weight? Im sure you have but anyway Im sure if you lose 10 lbs in the drivetrain you will def. feel it. Also I dont rember where I read it but also 5 lbs of unsprung weight is like taking off 100 lbs of sprung weight. Just food for thought

Regarding the carbon driveshaft - there is a ton of info at IWSTI, and that's where I got the group buy. While the feel of most mods fades after a few days, I find I am continually surprised by the strong "pull" my car has. Call BS all you want - this mod is NOT coming off, and my next car will have a carbon shaft, even if I have to have it custom made. The car feels that good! You need to realize the driveshaft spins 4 times the rate of your wheels; any frictional losses or inertia issues happen four times more often than the stuff immediately motivating your wheels. You also get rid of a crappy center U-joint that is bent at 2 degrees or so, and that sucker does NOT feel efficient. The 350z has a carbon shaft from the factory, and Nissan went so far as to make the steering wheel with a magnesium core - all to create a certain kind of feel that doesn't come cheap, or often. Or are they full of it too?

I read the review over on IWSTI and thought this sounded like a really good idea. After reading your review, I'm sold. I will be buying one of these at some point in the future...

Be carefull though some have had vibration problems with the CF shaft. May have been from improper shipping (which most reported) or improper balancing or possibly shaft bowing at high rpms????????????????????? The point is more than 1-2 have reported vibration so it must be addressed.

yeah, kinda seems that way. sure, people could just go post at iwsti.com instead as well i guess. i don't think nasioc would dig that, as it seems to try to appeal to ALL subaru owners.

What are some of the mods to make the sucker lighter? I mean damn 3350lb curb weight is alot for a track car that most people strive to create?
Thanks[/QUOTE]
Hmmm let me think....
Ha!
If You do this, Youll lose up to 800 pounds:

So far I have
stripped trunk(obviously)
JDM bumper beam
Pulled AC, lines, belt, pulley, and condenser
Do luck aluminum subframe
CF trunk / no wing (weighs 7 lbs!)
Braille battery
Lightweight pulley
Two piece front and rear rotors
Invidia dp and full Ti exhaust.
Carbon fiber driveshaft
Future plans include:
17" Volk ce28n's and better lighter tires (although the 070's are very good)
Poltec titanium or carbon lat links and trailing arms
Recaro cf SPA profi seats x2
Cobb or Hotchis sways
Aluminum or carbon axles
APS header and uppipe
High end Ti/ Aluminum coilovers
Titanium hubs (if the are produced and the price is not astranomical)
Perhaps a Carbon body kit if it looks good
I have done some calculations and 500-550lbs is quite within reason without gutting the interior. But it is VERY costly. I will probably keep the car for a long time so what the hell. My eventual goal is drivable 350-400whp at 27-2800 lbs

Just spend your money on good suspension, brakes, and then make more power. Weight is NOT the killer of a great track car, and 3300 lbs by todays standards is rather light. You want a light weight track car buy a RX7, miata, or elise
| thebigshow | 01-10-2006 04:12 PM |
[QUOTE=ndw1138]Aluminum or titanium hats. 7.5 lbs per front is my current savings and ~13 lbs per rear. Now this is of course the best place to loose weight on a car, but regardless my car weighed 43 lbs lighter post brake rotor/hat swap.
Turbo back - My muffler, midpipe and downpipe exchange (which still has a cat). downpipe was 8 lbs lighter, the midpipe was 13 lbs lighter and the muffler itself was ~11 lbs lighter. ~ 32 lbs of weight, plus hp.
[/QUOTE]
care to share which manufacturer(s)? thanks.

Ditching the 6 spreed and doing a PPG dogbox 5 speed and you'll save 100 lbs. And be a stronger transmission, plus the sale of the 6 speed would almost pay for the PPG box.

Heres what I have done so far to reduce weight...
Removed metal from in glove box door -1.4lbs
Removed metal plate from under steering wheel -1.6lbs
Removed owners manual -2lbs
Removed Spare tire, jack, tools, and spare tire cover -42.4lbs
Removed brackets from behind and below rear seat -15lbs
Removed rear center seat belt -2.2lbs
So thats 64.6lbs off
Next I replaced some parts
Exchanged stock wheels/tires/lugs for Enkei RPF-1 17x8.5 rims and Falken rt615 2554017 tires and kyokugen lugs
Saved 13.6lbs
Exchanged full turboback for modded hks downpipe and invidia TI cat-back
Saved 37lbs
Exchanged the stock intake box, silencer, cold air for a short ram with stainless filter
Saved 5lbs
Thats another 55.6lbs for a total weight savings so far of 120.2lbs
Swapping my front lower crossmember over this weekend to a aluminum custom gunmetal cusco v2, Wing to a syms one and maybe a lighter battery...
I plan on shaving 300lbs at least while maintaining a full interior and full drivability.
I also wanted to ask...Is the CF trunk really any lighter than stock? If it is I may get one, but I plan on painting it so if it is heavier then I wont bother.

| Freon | 03-24-2006 11:19 AM |
A CF trunk is probably lighter than the stock steel one, but not by a whole lot. But add the weight of the wing and you're getting somewhere.
I'd rather remove weight from the front of the car first if possible.

Davenow is correct, this does NOT belong in the 2.5L FFI forum. By trying to convince anyone that this is where "General STI" posts belong, you're basically ruining the forum for anyone with a Forester turbo, Baja turbo, Legacy turbo, and even the 06+ WRX's.
That being said, in older Imprezas there was plates under the steering column and in the glove box door meant to protect you in an accident by making you slide down, rather than into the dash. People have said these were 10-15lbs. each, though I've never taken a look. These may be in the new cars, as well, and would be an easy 20-30lb. weight loss. Who cares about an accident, if you're hitting the dash, the car is most likely totalled and you're not going to be in good shape either.

These are all good ideas to save weight, however i read earlier in the post about Lexan windows. This is definately NOT a good idea. All companies use the front and back glass as part of the structural rigidity of the car. Removing or replacing them with lexan will create handling problems, much like removing a steering stabilizer, sway bar, etc.
| bboy | 03-24-2006 01:40 PM |
We need carbon fiber doors and side panels to really drop weight. Replacing the U-brace with a Do Luck one saves you ~25 lbs.
| jtewell | 03-24-2006 01:46 PM |
Seibon makes a lot of carbon fiber parts for the 04 and 05 sti. You might wanna try checking their for wieght savings.
| dowroa | 03-24-2006 02:17 PM |
Hmm... some of the suggestions in this thread, and the various weights for those parts are useful in thinking about removing weight from the car. However, I have a question:
- What class are you tracking the car in?
If you are after a 'track car for fun', then take whatever you want off. However, if you are entering this car into a class, you have to deal with a lot of the weight, or work within a ruleset.
Just curious as I always see a lot of people say "I am doing this for racing/performance" and never really *think* about what they are racing in. To me, it is the same as putting a wing on a honda.
