500 is alot on a car thats all ready stripped. You can go to lowe's and get sheets of lexan and just cut it to fit your need. Not gonna need lots more stuff removed...

You can do it, but you won't be street legal.

Lexan windows, gut all internal body bracing. Inner door structure, hood, bumpers, bumper supports, gut the radiator support. Get under the dash and start gutting and removing. All the heater components, any leftover AC components.

If you are still stuck after that, take an old trick from that sneaky bastard Smokey Yunick and acid dip all of your sheet metal. Yunick was a master of grey areas.

Get rid of the brakes. Theyre for pussies and the only slow you down.

Post an image of the state of your car and we can make observations.

I know the interior is stripped and the sunroof comes out

METDeath

Yeah... fiber glass fenders will save you a bit of weight, but not much. maybe replace the hatch with CF and Lexan?

Also, you need to find some seriously light weight wheels and not stuff too much tire on them...

Also, not sure how much of your original wiring harness is still there, may want to remove unused wiring?

Get rid of the doors then use a crash bar and panels. You could also just weld the stock outer door skin to the crash bar and still maintain the stock look. Use netting for the windows.

Mafix

i've estimated about 20 lbs in wiring i could remove. that will eventually get done.
rules dictate that i need to have working doors. i am however working on lexan windows (which will net the majority of that weight i think)
half the crash bars will be removed as well. but that's 8 lbs. lots of work for not a lot of gain. but when you are picking like this it all helps.
rims and tires are NOT getting changed anytime soon. i've got a 9 inch contact patch and to change that will cost about 4K, all to gain an inch (and not lose any weight).
the cage and passenger seat will not be removed either. occasionally i have a passenger (even racing)
i'm not going to use a fuel cell at all. it will destroy the weight balance of the car and honestly for mabye 5 lbs. i can just run the car on damn near empty. easy weight there.
i can't imagine stripping anything more from the engine bay. there really isn't much there left to remove.
i need heat, they start racing in february...lol. but i have yet to remove the evaporator (3 lbs)
the body can't get any lighter. i've done what i can and without destroying the car (literally) i can't do any more.
i've kept my larger brakes to a minimum weight and size as well.

any other ideas?

Do lights have to be functional? Eliminate the headlight motors/lights. Remove rear assemblies and replace with fiberglass/lexan blanks.
Does the rear hatch need to be functional? If not, maybe remove gas struts, wiper/motor (not sure if the 162 came with rear wiper though). Maybe removerear hatch and weld in a blank?

I guess I should ask, what sort of racing are you doing?

Gut out the doors so they're just a skin and a latch.

good idea, I'd remove the hood release and trunk release handles and cables as well, if you're using hood pins and don't mind having to use the key to open the hatch. Or, strap the hatch shut and ditch the latch alltogether.

the stock spoiler weighs nothing really. besides the car looks stupid without.
also, i've abandoned the lexan. the weight savings vs cost and PITA are not worth it. we are talking about less than 100lbs. so f-that. guess i'll just have to get more skilled at driving, lol.

do you have power windows?......ditch them for Manual .... dash weighs a good 20lbs...remove and set your gauges up differently ?..........gas tank would be close to 50lbs...maybe find one from the yard thats smaller and will fit?

ditch your rear bumper support?...make new one of lighter materials?


the back hatch weighs close to that hundred pounds......can you make your own outta another material besides lexan?

A few more ideas if you are still going down this route.
I know a lot of people get rid of the alternator and run off the battery when they race.
Also, there is that sound deadening material on or floor pans that could come off (if you havn't removed it already).

Just some thoughts man.

passenger seat and everything with it removed, headlights removed, hood swapped for dry carbon one, splash gaurds gone, not 1 extra bracket left behind, all sound material removed, power mirror switch, most creature comforts, sunroof swapped, all wipers and motors and transmissions deleted, 99% interior removed, nearly every toyota extra on engine deleted...on and on. still 2500lbs.

And now you get to play with corvettes and vipers in FP as of the newest fasttrack.

Mafix

where did you see that? the vipers i'm not worried about, but the z06 vettes with good tires on them just scream around the track.

Corvette (2005-2012) (Naturally Aspirated)
this is the only one that sucks ass.
although all the vettes in my area run ss i believe.

wiring stripped (more like dramatically simplified), blower removed, heater removed, evaporator removed, all unused interior things removed, dash completely stripped
getting there. not much left inside the cabin left. under the hood is next. 1 harness section left to strip in there (body). then i'll be removing the coolant overflow. i don't think i'll have much after that. should be near enough to race weight after all that.
i've already filled 3 trashcans with stuff. which is amazing for those of you who have actually seen the car (dragon meet)

I'm amazed that you can still find stuff to pull off of that car.

I read your build a few years back and there wasn't a lot left on that car to begin with, any idea how much weight you've lost in this last bit?

Mafix
07-19-2012, 01:26 PM
easily 200+ lbs. i'll be corner balancing the car...again...soon. i'll know the weight then. then realign the car. then find the next weak link.
BTW firewall padding is heavy as hell.

Mafix
09-05-2012, 09:59 PM
damnit...all that work. still too heavy. i'm nearly out of weight to strip so i'm guessing it is an "is what it is" car at this point. 2600 fully loaded.

Hookecho

Plastic doors?

Mafix
09-08-2012, 06:17 PM
yeah no shit. target was 2200 unloaded. that's just not going to happen though. i need a coupe chassis to do that. and an n/a at that. although it is tempting to do one, with a 2.4l...that'll be nice and light. but i'm not made of money.

already done chris. and it's 2700 fully loaded...corner weighed and all. nothing left to cut out. and after this weekend i've found that i am physically at the limits of grip with all the tires...again. damnit.

now to get the car lower to the ground, correct the lower control arm angle, and contemplate the meaning of life.

I can help with that... the meaning of life is to end all other life that is not "us".

Sounds like you're at the point where you seriously have to consider how comfortable you want the car for regular driving, or start spending lots of time &/or $$ on custom parts.

I wonder if I could get mine into the 30xx weight. I remember weighing it way back when at 3285.
