"back-seat-remove" option.
 

I wish we could opt to "back-seat-remove" option when ordering. For those who wish to shed at least another 100 pound and have no use for the back seat. This way the manufacture could cover the surface in a neat manner.

I wonder if Toyota & Subaru are reading these posts.
What do you think?

I think this is one area where the aftermarket will pick up ie: with the Ford Mustang seat delete

LMAO @ 100 lb back seat

They must carve the seats out of dead hippos if they weigh 100 pounds.

Maybe its massaging chairs.

Or just use subwoofer box carpet that most closely matches and glue/tape it down..

it's not hard to cover that area so it's not wide open.

And the weight.. maybe 20lbs.

Yep good old MDF

With a little bit of fiber glass and some carpet you can get rid of them yourself.

Going to a single exit exhaust will save more weight then pulling out the rear seats. I'd prefer something more like the ITR, where the don't apply the undercoating and sound deadening.

I removed the rear seats in my 911 to give it the GT3 look...it saved me about 12-14lbs. I'd think 15-20lbs max in the FRS/BRZ

I doubt that deleting the less than 2 foot long 2nd exhaust pipe from the muffler will delete anything more than 3-4 lbs. However I'd agree that an aftermarket single exit exhaust will delete a substantial amount of weight. So would an aftermarket dual exhaust (to a slightly lesser extent). :party0030:

material ie: Titanium but w/ that also comes cost

That would be the biggest "gain" yes, but even a good stainless system will drop some poundage. The Invidia cat back system I have on my S2000 is 20lbs lighter than the stock exhaust, and it's stainless.

If I recall correctly, the stock s2k system is 50 lbs, and the lightest single exit systems weigh 5 to 6 lbs.

Reasonable stainless single exit systems can be around 15-25 lbs.

Exhaust and unsprung weight are the best and simplest weight reduction measures IMO.

I think if the 86 weighs in at 2680, we can get it down to 2600 with a proper selection of exhaust, wheels, and coilover suspension alone.

Thanks everyone for the input. So I think the exhaust and forged aluminum wheels would be the first choice for weight reduction.

Now they did say, the BRZ STI will have carbon roof and maybe carbon hood. But, wonder when the BRZ STI will show up.

That was just for the concept at the LA auto show. Would be nice if it actually makes it to the production model Sti.

I think I'm going to keep the back seats only for storage purposes. I need some where to throw my jacket and books.

The car already has an aluminum hood and roof...CF versions will save a few pounds, but might even add weight (most CF hoods have a glass backing... on the 04-06 STI/03-05 Evo a CF hood weighs considerably more than their OEM aluminium hoods).

Considering how light this car is (relative to all other modern cars with all the same safety items), in order to accomplish any further weight reductions (beyond wheels) you'll have to start deleting convenience items (radio/hvac/airbags/carpet/panels/glass).

Here is a good list of obvious easy weight reduction:

-exhaust
-wheels
-suspension
-spare tire/jack
-misc plastics (motor cover, etc.)

Next level:
-sound deadening from interior
-firewall mat
-undercoating from chassis

Next level:
-replace with FIA approved racing seats (illegal in US to remove side airbags)
-remove front airbags (illegal in US) racing steering wheel.
-remove rear seats, carpet, interior
-install cage and proper harness for seats


anything above that level is getting beyond street car level IMO. Even the racing seats are borderline. If you remove the side airbags, and then get in a wreck, the insurance company can deny your claim due to modification of the safety system.

Also remember, removing rear seats, or any weight for that matter, automatically puts you in the SM class for autox. SM can have engine swaps, turbos, etc. Big modifications! If you want to actually have fun in competitive driving, keep your interior in tact!

Don't forget to replace the heavy battery...I think it is at least 35 pounds. There are good 3 pound lithium ion batteries....for less than $300....

More importantly is lowering springs. Then this car will very nearly have the lowest COG in the world. Main reason its not already is the ride height.

back seats from the factory mean less $$$ on insurance. not planning to do any real weight reduction mods (maybe except for wheels and CSL style trunk lid made of aluminum/CF). this car is already fairly light weight for what it is amongst new cars.

MY GOD the ghetto shit people do to cars!

if done right it looks good....

I am going for this look myself

^^ That looks like shit.

Because it is in a tan interior (which neither the FR-S or the BRZ) will have, I didn't dig through the whole site to pick a black on black it gives the idea of a seat delete. :thumbsup:

here's a darker picture

I just don't understand the reasoning.

I'm going to replace 2 pieces of foam, with two pieces of wood?

There is no weight savings.

:word:

The idea in general is shit too., no piece of cloth is going to look right just separating the spaces.

The general idea is much like your opinion. Other manufactures do it from the factory (911 gt3rs, mustang boss 302) and they don't necessarily look much better. Not to bring up any extra bracing that may coincide with the rear seat removal, it's just aesthetics. If you don't like it, you don't need to go out of your way to say something negative about it.

None of those cars use a cloth with plain backing to cover their spaces, try again.

It really is just silly, if you want to lose weight that bad, do not add anything.

:word:

But hey, to each his own right. I don't plan on pulling stuff out of the car once I get it since I'm planning on it being a DD.

LOL at the "performance" drivers who will take out the back seats to save less than 20LB and the add 150LB of amps, woofers and speakers.

most people thinking of doing this should leave the seat in and spend the time you would have used taking it out and making some cover on reading up on driving theory and race technique.

its all ways silly to me that people that can't run consistent laps think that ten or 50 pounds is going to make a big difference. once you hit a plateau then try taking it out and see how little a difference it makes

plus as i see it, the car is 53/47 so you want weight from the front out, not the rear

keeps your seats

Best mod anyone can do straight out of the box is going to be tires. Removing this and that is trivial if you can't drive and if you can tires are still going to be the best place to start. Why is everyone complaining about a car that, in a world of 3,000lb plus "sports" cars, is already pretty damn light?

I can tell you removing the rear seat in

ALL IMPREZAS SUBARU

= 2 bolts, weigh=5lbs, literally the seatbacks and cushions are just very light pieces of foam.

You will be able to pull it out, and save it if you need it. Getting it without would save you 100, 150 bucks?

you are better off changing your front seats to save weight, and ditching the side airbags.

just loose 20 lbs , bonus you will look better too

Haha yeah, fix the nut behind the wheel first. If I pick this car up, you better believe I'm taking it to a couple of autocrosses before I touch anything on it.

^ THIS. You've read my mind good sir.

+ As mentioned, the Exhaust System, Wheels, and Springs/Dampers will be easiest ways to reduce the weight. Maybe even lighter Rotors would do some justice. If the CF Roof is offered as an option, take it. I'd imagine it'd only be slightly lighter, but definitely structurally more rigid.

I'd keep the rear seats for functionality unless you were focusing on track only where every pound counts.

I don't see the point. It's not a track car, you can get as much weight removed as you want, but you'll still be left behind but almost everything on a trackday.
Just enjoy the car as it is!
If you want a fast car to remove stuff from, just by an Evo or a old M3.

By the way, most of the light exhausts on sale drone a lot when cruising and are build in Taiwan / China, Invidia is one of them, I wouldn't fit on of these on my car.
A nice note it's good but when it doesn't compromise the daily use.
and the read seats...what's the point? They're just foam cushions, and they could always become of some use, it's just not worth it.
