Sup guys I just wanted some suggestions. I am trying to run a little quicker this yr when the track opens up in March or so. I’m looking for things that I can take off to reduce weight. I weighted the car at the track last time with full interior no ac it was 2650 exactly with out me in it. I know little stuff like back seats and spare tire and that stuff but I need to take off something to make it lighter at least 100-200 pounds. I don’t really have money for like a one piece front end or even if did it’s a street car so can’t do that.

So far im thinking

Remove back seats 20+ pounds
Spare tire w/ tools jack 30+ pounds
Remove Power stearing don’t even know
Remove plastic all around the back seats and taillight area 10 pounds


I already have weld rim they light as **** so that part is straight.

Thanks in advanced

Sorry buddy but the back seats are lighter then you think I wouldn't say 20 lbs.

Since it has 500 hp why don't you concentrate on traction problems to get your ET time down rather then minor weight reduction especially since it's a street car.

Here's a thread on TI.net which someone has listed the weights of the item's they have removed from their Teg. Hope this helps...

That's good advice, although his times are pretty damn good. But yeah, I agree that concentrating on traction will do more for his ET than minor weight reduction.

four words carbon fiber fuel door

with that much hp you gonna need a huge wing to keep that f.er on the ground

i have a GSR with 200hp. I should focus on weight... You have 500hp, you should focus on traction my friend.

but really
I removed the sound dampening material located in the back by the spare tire area. Its a long process with a hammer and chisel but if you get bored do it. I don't know what the differance in weight was but every bit adds up. Also ditch the ac components Like SHAYNED said and go for more carbon fiber and maybe some lighter wheels. I use desmond regamasters that are like 8.8 pounds a wheels.... Hope this helps...

If you have that much power, focus on unsprung weight, like lighter engine and transmission components, lighter drivetrain components (driveshafts, wheels + tires, any reciprocating/rotating parts). Power steering can save you some weight, as well as HVAC components like AC and the heater. Focusing on lightening the parts that actively move will help it drive and move much better.

Racermech

remember 100lbs is about .1 sec off you 1/4 mile times.

well he's running 10.8 right now on slicks with a 1.7 60-ft. time... got traction bars? If not those would probably make more of a difference than weight reduction.

mystikalstriker

change out the windows, but that will get pricy, cf hatch if you don't have one

Don't forget the aluminum flywheel. I'd go with clutchmaster, mine hasn't given me any trouble. Anyone know off the top of their head how much the stock one weighs? Has to be like 30-40 lbs right? Teg hoods are heavy as hell too, no need to replace the whole front end with a one piece, if you replaced the hood with a Carbon Fiber one and replaced the flywheel that'd have to be about 50 lbs of the 100-200 you're looking for, maybe even a little more. BTW, engine and trans aren't considered unsprung weight, unsprung weight consists of the wheels/tires, hubs, brakes/rotors, and suspension arms, pretty much everything else is supported by the springs.

Clutchmasters flywheel will save you 15-18 pounds maybe (stock is no more than 25 I'm pretty sure).

CF hood would save maybe 15-20 lbs. The stock hood is NOT that heavy.

These are some of the parts I've removed in my track car. The numbers listed are to the best of my knowledge, but do not get technical with me. I'm just providing some info for someone that wants to shave off some unnecessary weight.

If I had the money, I would also go with a fiberglass hatch with a FAL replacement glass, remove the power steering and purchase the Padawan kit and UR underdrive single pulley.

I know only from doing some 240sx's some extra things we have done that havent been mentioned here and might help you out are:

Light weight battery - maybe 10-15 lbs.
ABS - about 15 lbs.
Pulleys (unsprung weight) - 2-3 lbs.
2 peice rotors (unsprung weight) - 3-5 lbs
Carbon Hatch - 10 lbs

Every pound you can lose in unsprung wieght is good for about 10 lbs dead weight.

when i put my act prolite flywheel in the first time i weighed my stock on in at about 17lb

BTW this was in a 2001 integra gs

I've taken off quite a bit of weight on my road race EG, and though I weighed all the parts, my scale might show different weights than others so I won't bore you with specifics.

I will say, that you can EASILY lose 100+ pounds the night before a race, just in bolt-on parts alone. No permanent removal necessary! I'm assuming that your car has full interior other than what you listed.

To build a 500 hp car, you have to be pretty savy with a wrench. Use it on your interior, 100+ pounds easy!

There is no way a 3rd gen Integra rear seat assembly weighs 27 lbs. I've stripped out the rear of my car too many times diagnosing water leaks to know they're not that heavy... 15-18 lbs at the most.... unless later models had heavier seat assemblies or something.

sorry buddy, but your wrong on this one. Maybe it's your leather seats or something? But I have my rear cloth seats stored in my closet and just weighed them again, 27lbs. I was a little sketchy about my weight specs since I weighed most of my interior parts over 2 years ago, that's why I wrote in my post "do not get technical with me," so I felt the need to make sure it's correct. My specs are not estimates, I actually took the time to weigh everything listed.

weight reduction has always interested me. good thread, i know there has been other but i like to see some numbers.

how about before and after track times?

there is a reason why the Lotus Elise handles so well and is so quick for having a 190 hp/130 tq engine -it weighs in just at 2000lbs i believe.

what did you use to weigh the items? I'm with Patrick because i know forsure those seats can't weigh 27 pounds. Because ya know bathroom scales aren't that reliable.

skunked

allot of BS estimates in this thread. My GSR has been on Jenny Craig for the last two years and I have it down to 2060 w/out me.

The car still has all of its glass w/exception of the sunroof. All interior from the front seats forward and ll the rear plastic is still in. Power door locks and power windows still work as well.

PS, CC, AC,ABS, Heater/Blower, rear winshield wiper, air bags, bumper supports, sunroof, stereo, cat back, sound detoning have all been removed. Some of these items some may "need" if you daily drive the car but I don't.


And Bogarts/slicks on all 4 corners.

e-thugs now days, sheesh. Whatever already, go by your own specs.

The upper part of the rear seats with the metal backing is what weighs so much and yes they do weigh around 27lbs. I'll go weigh the set I have upstairs with my postal scale if you'd like. Anyway, the stock flywheel weighs roughly 16lbs (the GSR is actually about 2 lbs lighter then the LS I had). Thus a lightweight flywheel wont save you but about 8lbs. Dont forget to yank the rear seat belts as well.

just swap your shell, easy 600lb weight loss.
