If your speaking of the door reinforcement bar no matter what your doing that is the dumbest idea in the world. Street or track use that is unbelievably stupid.

A car that weighs less is much more fun to drive I think, and handles way better. And ya, can be a bit faster on the 1/4mile.

But if the weight in the car is balanced properly then there is usually no need for a weight reduction. Unless the car is really heavy.


I don't bother with taking out back seats or anything like that, but I do remove everything from the trunk, and remove a/c and cruise control and stuff I never really use or can do without.

HA! Sorry MOM! The JDM doors dont have the bars in there either. So... I guess in your world, the Japanese engineers are stupid too? Its a drag car fool!

Agreed. I have a daily and my plans for the coupe involve street driving it very occasionally.

92civlude

Not a DD. When inside the doors, there are access holes to service the regulator and door handle. I made the holes larger. I used a sharpie to draw out a template before I cut. The doors are really light! And its a lot cheaper than $1600 carbon fiber doors.

Uh, the JDM doors defintely have side impact bars in them.

If it is a daily driver it is stupid, i tried it, its loud, annoying, and ugly.

Thanks for that input Nancy.

I heard if you shave/reduce 100pounds of the car it like shaving 0.1 on 1/4 is that true! or what is it correctly?

Those bumper "supports" are actually your bumpers. You know that, right?

Your car is going to crumple like a tin can in even a minor accident. You might want to consider putting those back on.

Does anyone know the weight of a gas tank from a Civic Hatch? Mine is a '95 Si.

VTECROAR96typeR

here you go I dont know how many people know of this car Ariel Atom powerd by a Supercharged CTR b16b motor.

Its a supercharged K20, not a b16

I just put my heavy 89 EF Si on a diet. At Mission raceway it weighed in at 2240 pounds. So far I have removed
Dash 23.5 pounds
Heater box/core/controls/ducts 17 pounds
carpet 8.5 pounds
firewall rubber underlay 4 pounds
rear seat 25 pounds
door panels including speakers 16 pounds
rear quarter trim panels with speakers and hatch lid 29 pounds
exhaust (I run just a downpipe now) 40.5 pounds
total 163.5 pounds
car should weigh in at 2076 pounds
it ran 13.1 at Mission before weight removal
just an estimate using an E.T. calculator with 230 flywheel hp it should run 12.79 with hp staying the same

egimplantb20

well the only thing i dont have removed which will happen during the motor swap is the aBS pump which weighs a good bit. in my 94 hatch i have no....
carpet
air bags
sound deadning
ac and all parts (lines etc..,...)
ps
inner doors have been cutout for lock actuators (lost about 4 pounds in metal gaind a pound in actuators maybe)
jack
spare
dash bracing
no metal or styraphome bumper pieces
and plenty more im sure that i have lost more than 228 and with power costing more than pulling **** i have out i guess that its easier to trim down than build up.... hope this helped a little ill get a dry weight with everything gone and repost later

Pothole987

Cut out your intestines, they weigh like 20 pounds apparently.

seriously, i like my interior. and i hope all you people driving around without your bumper supports do know that if you get in an accident your dead.

hondacurious

door side impact bars and front/ rear bumper supports. save quite a bit. Its safe for the road right? ahhh who cares? who wants to go fast?

ElliotSiR

Why do I feel like these numbers are so similar to:

"Ok so guys I just bought a cold air intake, header, and muffler for my d15b8. Now the magazine said +15hp from the CAI, +25hp from the header, and +13hp from the muffler, and I believe everything I read. So I must be putting down like 123hp!"

I'm sure people have weighed their items so I'm not discrediting numbers, just seems goofy to think saving 100lbs will help you smoke your friends down the 1320 or win the next autocross event, really the only place weight reduction is going to actually help you is on a road course if the race is 50+ laps where a tenth to three tenths of a second a lap would actually be of some assistance to either catch someone in front of you or run away from someone you passed. EDIT: Oh and that's assuming you're good enough to race at that level anyway which 99.9% of the population isn't.

Disclaimer: I fully understand that in bracket drag racing and SCCA National Championship Autocross events every millisecond counts, my comments are directed at the average Joe who works 5 days a week but hits the strip or the autocross circuit once a month and maybe does a few HPDEs.

Just like my signature says keep the bumper support. That **** will save your life. Unless you want a motor in your lap.

Also gutted cars were cool when i was 18, I thought I was a badass because i was rocking a fully gutted hatch. Stock motor, with a few bolt-ons. LOL! Now being 30 and when looking back at it all, I shake my head and lolz. Keep the interior in the car, and build a motor. That extra weight wouldn't make a huge difference on a DD car.

I took the back seat out and picked up some spray foam at homedepot.

thanks for the idea of the thread... We just have too many all knowing KIDS here who dont understand weight reduction because their mother wont let them do that sort of thing in the car she bought for them.... Its all about looks with most of these children. The ones that do understand are following right along. Too many ****** ......

If your mother bought you your car then you shouldn't be doing anything... especially racing ... to it but paying her back for it.

Weight reduction in my opinion is an all or nothing sort of thing, if you want a measurable performance boost you need to go all out on weight reduction, otherwise minimal weight reduction is going to net you next to no gains at all.

My personal goal is to reduce enough weight to offset a full cage install, which will do several things (a) improve chasis stiffness (b) improve safety on track (c) make people not want to ride in the car.

There is nothing wrong with weight reduction, just make sure if you do it you do it right.

A lot of what's being discussed here is in a topic I started here in 2002:

92-95 Civic Hatchback Weight Topic

My 1992 Civic CX hatch weighs 1990lbs. currently. Super fun to drive, and for the people puking out "weight reduction is dumb for a street car" it's all personal preference. If I want some level of refinement or comfort I'll hop in my 1990 Civic Wagon w/B18B swap, or the 2011 Fit Sport in the garage.



You can have it both ways.

MauricesExoticP

Exactly, most people who own some form of modified car have a second DD as a backup or it'll be the the wifes or husbands car, what have you.

There are a ton of reasons to reduce the weight of a car, for me it is a matter of fact that a lighter car drives better than one that is several hundred pounds more heavy. If I can gut a car enough to add the cage and still end up lighter than stock I will do it.

Given two cars with similar power to weight ratios, the lighter car will be the winner in my opinion. Mainly because the lighter car will be much more fun to drive than the over powered lard butt car.
