my car is a lil bit less than 2300.

i removed the frame that supports the rear storage bins. i removed my sunroof. i replaced my spare with the lightweight one. i got convertible rims. i got an aluminum hood. efan. str8 pipe. i still got A/C n powersteering. no emissions pump. i also replaced the old 80s sound deadening crap with new 21st century one. (it weights a lot less). oh and no overflow tank lol.

i have all of my comfort. brand new interior n reupholstered seats. the only thing not comfortable in my car is the fact that my suspension is superstiff for drifting.


before i redid my interior. i had my interior gutted n i used to chirp on 3rd gear no lie. n this was before all the performance upgrades.

 

where do you get your sound deadening redone?

 

redone as in taken off? you can either melt it, or put some dry ice on it and chizel it off. both work well, though the dry ice route may be a bit safer

 

did you actually weigh it? the stuff you described is MAYBE 100 pounds worth of stuff, so i find it extremely hard to believe that it weighs under 2300 especially with a full interior.

 

Sound material is taken off with a wide scraper and a heat gun, or a light hit with the torch.


When I was into bmw's people could remove over 900 lbs from their e36 M3's before the cage, and that was with power steering.

but they have 3lb composite doors vs the 100+lb 3 series doors

 

3lb composite doors??? a door made of plastic food wrap would weight more..

 

 

I've removed alot from my vert. ALOT. I have Sparco 14 lb seats, 17 lb rims, No AC PS Spare tire STereo, Manual top, wiring harness gone through. I could go on and on. I've even chopped metal out of the chassis. But I do have carpet and in general it doesn't looked stripped. It looks a little bit different from factory though.
2690 lbs with a full tank, me NOT in it. As far as I can guess there probably isn't another 20 lbs I could remove without really seeing it.

 

Heres a not-so-stripped int pic

 

Okay, here's the new no-compromise list, based on comments, in no particular order:
Aluminum hood
Lightweight rims
Spare tire + jack removed, fix-a-flat in its place
Stainless exhaust
Flywheel
Replace sound deadening with more modern materials (remove w/ dry scraper and/or heat gun)
Lighter seats (Sparco 14lb.)

Maybe:
cut out storage bins & support frame
lighter/smaller battery

Other weight reduction, based on comments (compromises something):
emissions equipment
power steering, A/C
washer fluid reservoir & pump
carpet, upholstery, door panels, head liner, dash, plastic & storage bins, sound deadening
hatch shocks & straps
radio, speakers, speaker housing, antenna
sunroof motor & harness
cut off tire sump, door support bars
lexan windows & hatch
cold start assist
composites

Anyone sell aluminum doors? Other components? Lighter mechanical components?? (I'd like to see an alternator with aluminum wire, hehe)

 

You dont have to cut out the storage bins and frame... just take the screws out :p

 

Strip everything, as much as you could. And what the guy above me said. Anyone had experience on 2+2's?

 

there's a guy in Japan who sells fiber glass doors, not skins but whole doors for like 125 each plus shipping. he also sells FB fenders, hoods, and rear hatch main frame I believe. I'll have to look around for his site.

 

rep rep 2386lbs.... and still has full dashboard and full sun roof crap!
Pics in random order!!!

 

No, as in switching from the "80's crap to the 21st century crap" as the poster on page 2 said.

 

Hmmm........With the minimal ammount of weight that it actually takes from the car and the added noise, I dont think im going to be taking the sound deadening material off of my GTUs like I planned.

 

Sound deadening weighs a good amount ive removed alittle under 30lbs from my car and ive weighed it. Thats not including the carpet which weighed about 15 lbs.
So far ive removed the following

all carpet and sound deadening
powersteering
ac compressor
ac condesor
all ac lines
storage bins and rear carpet
spare tire and jack
single exshuast<<<<much lighter
removed rear exshuast heat shields
one seat
acv
smog pump
ps and ac bracket
cruise control

Id say gut it...Ill never look back the steering response and braking have improved alot not too mention the ecceleration.

 

The company is MAShaw and they have the strongest stuff around, unfortunately the only people who have them are people who are get sponsored builds -$$$

They are 7lbs as full doors and if you gut them they get down to 3


There ought to be a resonably priced fiberglass parts rx7 company. widebody fenders, sunroof replacement panels, hoods, doors, etc

 

would they make doors for the FC?

 

Nobody would buy them. Everyone will say they will, but when it comes time to shell out cash everyone loses interest. Just the way it goes with FC owners.

 

Once you get the weight down enough, removing P/S won't be sacrificing much at all. My '87 MR2 weighs about 2300lbs and feels great with manual steering. What's the lightest S5 TII we've got on here? And does anyone make carbon driveshafts? That would shed some killer weight as well as cutting down on parasitic drag.

So far I've removed:
carpet
spare tire and jacking equipment
A/C
emissions equipment except for cat
replaced power mirrors with fiberglass RE Amemiya mirrors
power seatbelt motors and tracks
rear washer bottle
stereo and speakers
lighter headlight units (diamond crystal or whatever)
lighter aftermarket fogs
3" stainless single outlet exhaust
a bunch of little fiddlybits like unused bolts and clips


I gotta get mine on a scale to see what it weighs... I've still got to get rid of the rest of the deadening, get FG fenders, sunroof, hood, and rear hatch, rear glass from a non rear-wiper model, (to remove rear wiper), remove the strut tops, jack clip, antenna mast, power steering, install lighter seats and steering wheel, switch to manual windows, and get lighter wheels, tires, and suspension pieces. I'd also like to get a custom crank pulley made because it will only need to power the alternator (because I plan to install an electric water pump to reduce parasitic drag even further). If I make it a dedicated track car I'll go for the FG doors and remove the heater core and HVAC unit. Oh, and does the fan shroud serve any purpose other than preventing you from cutting your hand off? Cuz I'd like to remove that, too, as well as possibly installing a SPAL electric fan in place of the big stock clunker.

 

Oh, and everyone should pick up the August issue of Sport Compact car and read the article on the Opera S2000 buildup. They got an S2000 down from 2976lbs to 2167lbs caged with a full interior and all amenities by using carbon body panels, drilling/chamfering all nonessential chassis pieces, stitch-welding, lightweight wheels/suspension, racing buckets, etc. . Absolutely incredible.

 

Yes, I read that artice too. That guy put an extreme amount of work into that car.

 

Anyone notice how an S5 glove box hact is about 4x heavier than an S4? or maybe mien was just lightened in my S4. That'd probably be like 4 lbs right there.

 

There is a metal plate behind the face of the glove box door.
