I now own a 2-seater Impreza
�
�
I was bored on my day off and decided that I didn't need my backseat. I drive alone 90% of the time, and my GF is the only other person that ever rides with me. So now my car has all the practicality of a two-seater roadster with 1/2 the fun factor.
I went to the fabric store and got some black headliner material. I didn't really know what I was looking for as far as material, but this looked like it would do the job. The material was about $12.
Removing the back seat was pretty easy except for the shoulder belt devices wedged in the corners. I got the right one off after a little struggling, but the left one was angled so I couldn't get my rachet in there. I was getting like 1/32 of a turn each time and ended up cutting my finger. Annoying.
I got everything unbolted and attached (temporarily) the headliner material with on bolt at the top, two bolts at the bottom and some duct tape on the underside to keep it from flapping around. It doesn't look too bad, and it looks much better than just seeing bare metal and wires, but I still need to attach it better.
Pros:
- removed about 30 lbs (2 cushions + bolts and hardware)
- slightly better response when I step on the gas while cruising
- car seems to a jerk a little less when starting from a stop
Cons:
- 2 person seating capacity
- hearing the annoying high pitched whistle of the fuel pump
- trunk rattles when going over hard bumps
- increased road noise
With all the crap I've taken out, my car is about 2300 lbs, and I can definitely feel the difference when compared to stock. (stock FWD L is 2400 lbs). Throttle response is better and passing is actually possible now.
I probably could've gotten the same throttle response by making a Home Depot intake, but my obsession with less weight doesn't require $$$.

BTW, i discovered that you can remove the piece of metal that constitutes the foot rest next to the clutch :p Doesnt weigh much though :lol:

Now all you need to do is get some really long seat sliders so that you can pull over and slide the front seats into the back and make it a mini limo....

Umm lets see you ripped out your back seat and replaced it with some 12 dollar fabric and some duct tape...were you on acid or maybe you smoked some crack when you thought of this...like a hundred pounds lighter thats like an 8 year old kid in the back seat...it aint making your car that much faster...now you have a some place to sit and smoke that crack you like so much...
| subarud | 05-20-2003 05:32 AM |
woah, hater huh?
Removing weight is one of the best things you can do for a cars performance. In the end, it all adds up...
Less weight = better braking, handling, acceleration, etc
Removing a couple hundred pounds off of a car (not easy) is a cheap and very efficient way of making a quicker car (Especially an L:lol: )

hey! i found a way to drop 30 lbs from my car. in about 6 weeks, after my diet is done, my car should hit the 12s on the track :rolleyes: right?
lets see some pictures of this frankenstein back seat.

Hate to tell you, but the rear seat assemby isn't 30 lbs...
At most each piece weighs 3lbs, so that's 6 right there...
The hardware will be a stretch at 1 lb as well...
That sounds like 7 lbs to me...
throw in the seat belts and tensioners for maybe another 5 and you are up to 12 lbs...

Not to make waves, but my rear seat in my 02 wagon was definitely heavier than 12 lbs. the bottom cushion is light, but the back panel is quite heavy ~20+ at least..
id like to see photos of your removed seat.. sounds interesting.

unless you take out about 500lbs you wont be able to
knock off 1sec off your 0-60mph in the streets, so i decided to keep it in the car. 30lbs isn't going to do much for a wrx.

the wrx back seat is different than an L back seat.
I dont know if his L has a pass thru or not.
W/o the pass thru it is very very light.
with the pass thru it is heavy.

Yeah I was guesstimating from somebody who said everything weighed 30 - 35 lbs. I should get a scale and weigh everything though. 30 lbs does seem optimistic - maybe like 15 is a better estimate.
I figured some of you would think I lost my mind. I thought about my level of insanity before I actually went through with removal. I wouldn't have done it if I had a nice new WRX, but it's just a ratty old L, so I'm not worried about resale value or anything. But this it, I'm done tearing out the interior of my car - the next step is ultra expensive lightweight parts, which I don't have the money for.
And I wasn't looking for better 0-60 or 1/4 mile times, I just wanted to make my car a little more responsive, which I did. Tearing out the backseat may not have had much impact on acceleration, but that and everything else I did made a noticeable difference.
I might take some pics when the backseat area looks a little more respectable. It looks half-assed right now.

we don't question ur sanity, u've proven to have none. un;ess u rig something up for the back, whether its extending teh trunk space or dropping in a couple of subs, the n chucking the rear seats qualifies u for teh [B]Heir to the King of Idiots[/B]. :lol:
Honestly man, level with us that ur drug habit is out of control so we can take ur money instead of some non suby owner:cool:

ignore these guys. Yes for some this may be a bit extreme, but if weight reduction is a goal of yours (as it should be for more people, if they were more educated about the results) props for doing this. I thought about it, but my backseat is used too frequently. And yea I'd love to see some pictures when it's done.

All the people who are bashing weight reduction have probably never felt the difference that 200-300 lbs. makes, and probably never will. [b]To all the haters: please stick to your carbon fiber boost-guage a-pillar mounts, "intimidating" blowoff valves, and poser STi badges and stickers... :rolleyes: [/b]
To those who are actually part of this conversation: the 98-01 2.5RS seats (fixed back, no passthrough) were very light, but if he's got a rear seat that folds down, 30lbs is probably accurate. The seatbelt assemblies are pretty heavy, especially the inertia reels.
There's even more weight to be saved in the front seats, but it costs a pretty penny. I'd estimate that the stock front seats (plus brackets/sliders) in my car weigh a good 30-40lbs each.
I would recommend that you avoid making any permanent modifications to your car though, it would suck if you change your mind later.

pics would be nice...

BTW, I'm not biased, I use my back seat too, so I left it in. Would love to pick up a european or japanese seat that folds all the way down though. I like fold-down rear seats, they're good for beach trips...

I would do this if I didn't use my backseat any, except instead of putting carpet over it, I would strip it down to bare metal. A 2 seat wagon, now wouldn't that be neat.
I know my seats are completely different, but I had my interior out the other day doing some wiring and it's EASILY 30+ pounds for the back seat...

I had my back seats out the other day and weighed them, each was ~15lbs.
So yes, it is 30lbs.

there is no way on earth the bottom bench portion weighs 15 lbs... unless the L uses a really different piece... I have taken mine out many times and it weighs 2 maybe 3 pounds... It's foam with fabric on it...

That isn't always true the weight removed for those gains should be a percent of the total car weight, location, etc. Maybe for a Suby this is right, but for a Corvette 100lbs isn't going to be much.
Lighten the driver anyway....most of us can afford 10 pounds off the spare tire ;)

Losing 100 lbs has the same effect on the power to weight ratio as gaining about 5 HP.
stock weight - 2400 lbs
stock HP - 110
stock weight/power ratio - 21.818
add 5 HP - 20.869
lose 100 lbs - 20.9
Reducing a little weight on a lighter car has more of an effect than on a heavier car.
2400 lbs - 100 = 4.16% reduction
3400 lbs - 100 = 2.94% reduction
Just so you know, my backseat did not have a pass thru. It is just a lot of foam and fabric, but I think they weigh more than 3 lbs each.
scotty305 - you have no idea how many permanent, completely irreversible modifications I've done. I'm past the point of worrying if I'll regret it or not.

When I take my sub (~40 lbs), spare tire, and jack out of the car for an auto-x, I swear I can feel a difference. That's "only" about 70 lbs. I can imagine that 100 pounds off of a 2400 pound car would make a noticeable difference. I don't know why this guy got flamed so much. His lack of a back seat is worth just as much power as your blingin' air intake.

Except with an intake, you get to keep your backseat, and you get a nifty new sound from the engine, rather than an annoying whistle from the fuel pump. Buying an intake makes more sense than losing the backseat. When you're poor and bored, logic goes out the window.
Also, I noticed the fuel pump is louder when I have a full tank of gas. I didn't hear the whistle as much and thought I was getting used to it - than I filled up my tank and it came back. And what I thought were my front brakes squealing is actually my rear brakes. Not having a backseat made it easier to tell what direction to squealing was coming from.

if him losing 100lbs is as good as 5hp
don't forget that not only is 100lbs more to a 2400lb car than a 3400lb car, but 5hp is mroe to a 110hp car than a 227hp car

I think another thing that is not being pointed out that, lets say you do save all that weight in the back, you're upsetting the front/rear weight balance even more that may help for straight line dragging but hurts in cornering performance and worsens understeer. But since the weight loss is pretty minimal, it really doesn't matter ;)

you have any pictures to show what your 2-seater looks like. cause i have a 99 OBS and i NEVER use the back seat. Well since a 2 inch drop and 18's on my car it sucks having someone sit in the back. A little rubbing here and there so i am thinking of doing the same. But wanna see what it looks like.

Aparently the RS is closer to 58/42, but I just checked the door panel on my L and the ratio came out closer to 52/48, and wagons have the better weight distribution due to the extra weight on the back... WRX's have far more equipment in the front of the car, and have a 61/39 ratio with something closer to the RS ratio for the wagons.
There are alot of variables in this though, like some of the L's dont have ABS and have lighter hoods than the RS along with a lighter clutch system, tranny, and master brake cylinder, among other things.
So its pretty easy to get the ratio on most of the N/A cars close to almost exactly 50/50 if you try hard enough. (relocated-to-trunk battery, lightweight front bumper beam, no A/C, etc.) But with a WRX or a turbo car you wont be able to get quite as close...

[B]Aparently the RS is closer to 58/42, but I just checked the door panel on my L and the ratio came out closer to 52/48, [/B][/QUOTE] Now I don't have an L, but I can say that I've never seen a car that has unladened weight distribution info on the door jam panel. What it lists there is max gross weight, which is irrelevant.

what kinda cf hood is that brucelee? can we see some pics? and a review maybe too?
| garface | 05-25-2003 05:42 PM |
According to iSR, the stock RS hood weighs 34lbs and the OEM Subaru aluminum hood weighs 15lbs. The really good CF hoods probably weigh 7-8lbs because they don't have the crap fiberglass frame underneath.
| Handsdown | 05-25-2003 07:02 PM |
yeah CF hoods are insanely light... i lifted up SpamMansXe's this last weekend and its really really light, i wouldn't besuprised if it was 14 lbs or less.
has no one talked about the placebo effect? when you do something and you're thinking "wow there's like 100 lbs less on my car" you'll think it preforms better, when in reality the gain isn't near what you think it is. for example... when i fill up to a full tank of gas i feel like my car lost 20hp. or when i'm lugging around one of my friends, i feel like i lost another 20hp. i mean you have to look at it in a subjective point of view.
a car with all the normal weight reduction done to it(~100lbs) and a full tank of gas is going to behave similarly to a stock car with a 1/4 tank of gas.
obviously the weight that is lost is lost in different areas so handling will be different... but acceleration and power/weight ratio will be about the same.

Weird thing is that my car feels faster after I fill up the tank than when I have a quarter tank, same thing in every car I've driven and I know other people who say the same.

Ya, I realized that after posting it :(
I honestly have no idea what the distributions are, I got rid of all my old dealer brocures that listed specifications a couple months ago...
BTW, the bumper beam weight reduction does improve handling as you are taking that weight directly off the ends of the car.

[B]thats why you never fill-up full :) [/B][/QUOTE]
If you're not filling up full because of the extra weight and extra gas to carry that weights it's pointless. No matter how little gas you put in it will add weight and burn some gas carrying it.

[/B][/QUOTE] Why is it pointless? If a full tank weighs 100 pounds, but I never fill up over half, wouldn't my car be 50 pounds lighter? What's the problem with that?

Ok, edit for the extra weight I'm not talking about pure weight, when I autocross I go down to 1/8. But I've heard the argument not to fill up completely for gas mileage purposes.

It works then, too. If you're always carrying 50 pounds less weight, your car will get better gas mileage. You'll waste more time going to gas stations more frequently, but that's the tradeoff.
| rohde88 | 05-27-2003 12:34 AM |
No, you are still arguing about something different, something I agree with. I am talking about the gasoline weight, for example an airplane has to carry say, 30,000 lbs of gas and 2,000 lbs of that is just for carrying that gas into the air. Some people claim that putting in say 25k will save the 2k needed to lift, but 1,500 will still be needed to lift the 25.
That was a bit complicated, but maybe you see what I'm arguing.
