Weight saving measures?
 

Since the main strength of the BRZ/FRS is really being light with great handling, reducing weight further would only improve upon the handling, braking and overall performance.

How much weight can you save by removing the spare tire /jack etc. and replacing the battery with a dry cell light Odyssey battery, removing the rear seats and using light weight 16" wheels?

40-60lb?

50-80lbs. might as well delete the AC.
and i find it funny that this car needs a 8 speaker stereo system. remove 4 of those speakers and the wiring.

You could probably save at least 10 lbs by searching first.

Not to go off topic but OP, does it say you drive an 09 GTR and a 12 optima? Did I read that correctly? Does not compute.

:lol::clap:

Yea I agree. If you own a freaking GT-R you should somewhat already know about weigh savings!

How much do you weigh yourself?

A good quality stainless steel exhaust system could shave off 20lbs. Even more if you went full titanium and/or replaced the exhaust headers with stainless steel pieces. Lightweight wheels could easily save you 5lbs per corner.

I think I'll get it under 1100 kg. I'll remove everything inside except dash and door panels. No navi, no A/C, lightweight rims, exhaust, CF roof. 1000 kg if no roll cage.

.

LOL

What does not compute?:thumbup:
The GTR is for fun weekends; the Optima SX Turbo is a great daily driver and the FJ is a about as good as it gets for a 4 wheel drive sporting SUV.

hahahah :happy0180::thanks:

Looks slow ;)

My f-ing spare tire weights a solid 30 pounds. Man that thing is heavy and its not even a full size spare.

I like how you guys are trying to get below 2600 pounds in the FRS...How low can you go?

:lol:

I used to own a 1994 NSX; I removed the spare, jack, engine cover, stereo system, speakers [14lbs for each of the door speakers and 12 lbs for the one from the passenger footwell!!], replaced the battery with an Odyssey [16 lbs] and on days when I felt like it, I even removed the passenger seat [50lbs]....for a total of about 110 lbs. So that the curb weight was just about 3000 lbs.

You have to remember one thing. In a car that is already light, removing every lb has a much greater percentage decrease in weight than in a car that is heavy. That is why the FRS, which is already very light, any few lbs of weight decrease will make a very significant change in acceleration, braking and turning. Top speed is not affected much if any.

I loved that NSX and should have never sold it. It was a much more fun driver than the GTR. That is why I am so excited about the FRS. It should be a FUN car.

You could save more weight by replacing the factory seats with some aftermarket recaros. Maybe 15-20lbs per seat?

As an aside I do NOT like the way those headrests cant forward so much. Is that going to be an issue when you're wearing a helmet?

The headrests are adjustable and a few reviews said they don't jut into your head.

Alright I hope so, b/c I have a big head!:thumbup:

I don't know why all these headrest designs of late have the headrest pointed so far forward. If people are too stupid to properly adjust the headrest themselves then if they suffer any soft of head injury as a result they're probably not losing too much computing capacity:laughabove:

Damn you had a NSX and you have a GTR?

U da man dawg!

Did you ever have a Supra Twin Turbo?

Actually I had a white 1994 Supra TT !!
That thing was a straight line machine. I got more tickets in that car than all others put together. Sometimes the cops would stop me for any excuse in the world, like you need to put front license plates on or just to check my license and insurance and crap like that.

The Manual FRS gear stick looks almost identical to the Supra's where you had to lift the ring to put the car in reverse.

I am going to have to dig up some pictures of the Supra, it was a while ago.

I am a Japanese sports car junkie. Other than the RX7, I have had all the Japanese sports car including the Miata and the Honda S2000.

The Miata and the S2000 have the best manuals in the business by far. The S2000 is great for track but on the every day drive it seriously needs more low end torque [hell needs more torque period]. I used to feel guilty beating the engine mercilessly to get much acceleration.

If the FRS is anywhere near as much fun to drive as a Miata, it is an ABSOLUTE winner because it has the advantage of being a tight proper coupe, with two additional seats and more power.

By all accounts it will be at least as much fun as the Miata. We are lucky.:happyanim:

Holy hell! 14 pounds speakers? that's ridiculous. If speaker technology hasn't advanced any since the NSX that's 112 lbs we can cut out of the FR-S right there! :bellyroll:

Low calorie high protein diet should help.

I know! Considering all the money spent on making the NSX all aluminum to decrease weight and then to put these ridiculously heavy speakers sounds and was preposterous! I hardly ever listened to the stereo anyway, what with the glorious engine singing right behind you:)

Funny only because on the first page of that thread is a link to a thread that preceded it and also talked about reducing weight in vehicles.

SEARCH FAILED!!!

Uhh,.. that was his post as well. :laughabove:

All things considered the NSX was still incredibly impressive. If I was a bit older and had more disposable income I'd be looking for an older NSX to pick up as a weekend car. IMO for the current prices there's not many cars that beat it in the looks department.

Instead of weight reduction how bout lowering springs. Lower the car one inch and it will have the lowest COG of any car in the world. Sorry off topic I know.

Losing weight helps almost everywhere. On your car or yourself.

I had an MR2 Spyder which I removed about 200 lbs from and got it under 1975 lbs. Even with 138hp it was a fun little car. I hope I can get this one down to about 2400 lbs.
