DC2 Weight Reduction

[LaZaZaL89]

Hey I know lots of people my age wanted to start weight reduction on their cars but dont know where to start, so I was doing some research on weight reduction and couldnt find too much around on the forums here, mostly because im useless with the search function. But I found this on another website about DC2 Integras, even though I drive a DA9 I found it pretty usefull too, i converted the pounds to kilo's.

It is from the website www.importmodifications.com (http://www.importmodifications.com/integraweightreduction.html)

1994-2001 Honda Integra


Listed below are some easily removable items:

1. Passenger Seat - Removing the passenger seat is a very easy and effective way to give your Integra a small boost in power. The nice thing is that the seat is only held in place by 4 bolts.

2. Rear Seat - The rear seat is a little more complicated to remove than the passenger seat. When removing just remember where everything goes and it should be easy to put back in place whenever needed.

3. Rear Seat Cushion - The rear cushion should be removed at the same time as the rear seat.

4. Floor Mats/Front and Rear - This has to be the easiest weight reduction available for the Integra owner.

5. Tire Floor Cover - The tire floor cover is right underneath the rear hatch carpeting.

6. Spare Tire and Jack - Another easily removable item.


Intermediate Skill Weight Reductions

The weight reductions included below can even prove more effective than some of the reductions included above. However, once you start removing these items you are taking away from the cars overall appearance and in some cases its more predominent ammenities.

7. Air Conditioning - Be sure to remove everything from the engine as well as behind the dash. Should be completed by the experienced only.

8. Front Hood - Replacing the Front Hood with a lightweight fiberglass or carbon fiber hood is a great way to remove some weight around the front end of the car. If you dont intend on replacing the entire fron hood you could also remove the sound dampener on the inside of the hood. This should help in cooling your engine a little.

9. Stock Wheels - Replacing the wheels is a must for anyone seriously interested in increasing there cars performance. The stock wheels are quite heavy and can be replaced with a variety of aftermarket models. We would suggest searching for lightweight wheels. Replacing your wheels with lightweight wheels will dramatically increase your cars acceleration. We suggest not going over 17 inches if maximum performance is what you desire to achieve.

10. Front Drivers Seat - Replacing the two front seats in your Integra with lightweight racing alternatives can save you a dramatic amount of weight. We suggest going with lightweight carbon fiber or fiberglass seats.

More Weight Reductions

Stock Flywheel - Can be replaced with lightweight aluminum flywheels.

Stock Steering Wheel - Can be replaced with lighter performance steering wheel with no airbag.

Passenger Airbag Removal - Can save some extra weight as well. (Not recommended for normal driving)

Interior Panels - Both the drivers side and passenger side front door panels as well as the rear panels can be removed.

Stock Speakers - The power antenna as well as the stock stereo and amplifier can also be removed to save weight.

Rear Hatch Cover - This can simply be removed whenever needed.

Replace Stock Exhaust - The stock Integra exhaust weighs considerably more than some of the aluminum aftermarket exhausts. We suggest going with GReddy Cat back exhaust or Borla Cat back.

Wiper Motors - Although they are generally needed under almost all driving conditions they CAN be removed if need be although we do not personally recommend it.

Carpet - Removing the carpet as well as the carpet lining underneath will reduce the cars overall weight.


Hope this helps,

Stock Weight - 1199.55Kg's
Stock Wheel Weight - 7.41lbs each/without tires

The 1994-01 Honda Integra's weigh approximately 1199.55Kgs, dividing by the horsepower of 140, we get about 8.57Kgs/hp.

a summary of the above

take out anything and everything you don't need...

[Kazaf]

Don't think you are allowed to remove the airbags from a vehicle, along with the passenger seats too.

[xntrik]

2. Rear Seat (13.18kgs) - The rear seat is a little more complicated to remove than the passenger seat. When removing just remember where everything goes and it should be easy to put back in place whenever needed.

I dont remember my rear seats weighing this much wtf. LOL

[LaZaZaL89]

@ Kazaf
That really sucks if you cant remove the passenger seats >.<, and yeah the guys at motoquipe said it was illegal to remove airbags, but it does say not recommended for normal driving :)

@xntrik
13kg isnt that much when you actually lift it though, did you weight yours lol? especially when you consider the size of the seats only weighing that much... Nice car btw LOL

[dynosaur]

6. Spare Tire and Jack (14.55kgs) - Another easily removable item.


it is illegal , dude.

I suggest u just go to get a shopping trolley , install ur engine on there and then drive it....

then ur "car" will go alot more faster.......if u want to "lightweight" lol

[xntrik]

i swear it only weighs like 5kg at max.
>_> my bonnet was actually more heavy.
my spare tire and jack feels way more heavier.

[milkman]

Gotot the toilet before you drive. I weigh roughly 2kgs more at night and that can only be attributed to holding water among other things..

[ricki_kalsi]

I found that awsome! Thanks man... Most of this stuff I have done, or I remove before a track day.

I must have to say, this is not recommended on a stock DC2R with stock sussy. Reason being is that it throws out the weight distribution. Did you know Honda Japan balenced the sussy with a 45 - 55 kg male in the car?? Who the f**k weighs this little! This is where after market coilovers come in handy, where you can adjust the corner heights depending on corner weights.

Make sure you get the corner weights done when you are sitting in the car, with all the weight reduction you are going to have done for a race day, where cornering and stability really counts.

[Paul1985]

it is illegal , dude.

I suggest u just go to get a shopping trolley , install ur engine on there and then drive it....

You sure that ones illegal?

[bennjamin]

removing anything that is OEM from your car , is illegal unless engineered.
IE defectable ! Guys , be safe and dont get too carried away , some things are there to save your life ! (airbags etc)

[ricki_kalsi]

when you remove your back seats, take out your seat belts also... It saves a bit of weight there. Also the side mirrors are a bit bulky too - replace with Vision /Spoon mirrors.

Also... Adding stickers actually reduces weight! :P

[LaZaZaL89]

Also... Adding stickers actually reduces weight! :P

:O, im going outside to sticker mache my car right now!

[ricki_kalsi]

hehe.

[LaZaZaL89]

Hey guys, do you think if you replaced a steering wheel in the DA with another non honda one it would be defectable? The guys at motoquip said you only need an engineering cert if the wheel is under 300mm in diameter, because it doesnt have an airbag...

Your thoughts?

[milkman]

Anything non-standard is defectable. In saying that you're more likely to get in trouble ifyou replaced an airbag'd wheel with a non-airbag'd wheel.

[ricki_kalsi]

If it has an air bag don't replace it. If it doesn't bring on the Nardi Deep Dish!

[shebangs]

That's full of shit.

Front and rear seats don't weight 16 and 13KG respectively.

[LaZaZaL89]

if only they didnt cost so much :(

[LaZaZaL89]

shebangs, you comparing that to an integra or your EG? im just quoting the site as well, and its american... by that i mean the seats they use in their models may weigh a bit more, i dno why they would though

[shebangs]

shebangs, you comparing that to an integra or your EG? im just quoting the site as well, and its american... by that i mean the seats they use in their models may weigh a bit more, i dno why they would though

No, I used to have a DC2. And I've stripped the interior of both the DC2 and EG.

[DC2108]

correct me if im rong DC2R 1087KG ?

[LaZaZaL89]

hmmm, ur probs right, im started to think this site is full of shit in many ways LOL

EDIT: you are right, according to drive, the kerb weight of the dc2r is 1087kg, im gonna go through and delete all the amounts of weight

[m0nty ITR]

I just removed all interior trims excluding door trims and upper dash from my car. This included passenger seat, all seat belts, rear seat, roof lining, carpet, centre console, stereo and speakers, tools, spare wheel, floor brace, both airbags, bonnet, rear wing, AC system and stock wheels.

Will be refitting carbon bonnet and rear wing, Sparco wheel, Bride seat, 6 point cage, Carbing front strut bar and Takata harness. I'd be amazed if I got 50kgs off the car. When it's all done I might get her on the weighbridge and compare to standard weight of 1150kgs.

It's one thing to strip a car, but retaining it's daily driven characteristics is another thing. When stripping cars out for racing you have to add other things which increases weight. All in the name of safety I guess.

[xntrik]

correct me if im rong DC2R 1087KG ?

Yeah thats correct.

[Chuckz]

i removed the driver the other day, and my car lost some wright :p j/k

1. Passenger Seat - Removing the passenger seat is a very easy and effective way to give your Integra a small boost in power

Lollllll

[ricki_kalsi]

Recaro's do weigh around 16 kg's each as I remember. I THINK!!! They are heavvyyyy. IcemaN on the forum weighed them.

[LaZaZaL89]

Lollllll

lol, i myself dno why ud wanna remove a passenger seat for a tiny boost in power, whats the point in having a car if you cant drive anyone but yourself... may as well get a bike :P, unless you want a bit of safety metal around you...

[ricki_kalsi]

I guess this thread was intended for removing weight for racing purpose... where pwr to weights really counts.

Doing half the stuff for street sounds stupid.

[danny_2132]

is it really illegal to remove the spare tyre and jack?? lol

[string]

lol, i myself dno why ud wanna remove a passenger seat for a tiny boost in power, whats the point in having a car if you cant drive anyone but yourself... may as well get a bike :P, unless you want a bit of safety metal around you...

Bikes don't get lateral forces around corners, cars do :)

[EG30]

Our dc2r aust spec weighted in at 1113kg, on the scruntineering weighbridge at my local race track with 1kg resolution. It had bit less than 1/4 tank fuel, itr floormats, all other junk removed from car, oe space saver spare wheel, tools and jack intact, washer fluid about 80&#37; full.

[tekung89]

imo. jack, spare wheel, tools etc deleted, lighter hood, aircond deleted perhaps, light weight pulley and fly wheel, header and exhaust and lighter seats. everything else is jus too little. rear seats weighed almost nothing to me. 5kg max

[Fitzy]

remove all interior carpets and seats.
use dry ice on the sound deadening stuff that you can see thru out the car.
helps a little.
like everything else.

by the looks of it, youd need it wth those giganormous chromies.

4. Floor Mats/Front and Rear - This has to be the easiest weight reduction available for the Integra owner.

lol..

[u mad?]

bump.

[newpaddy3]

They reduced overall weight by around 284kg.

Thread Revival....

I weighed my dc2 (vtir) on the scrutineering scales at phillip island on the weekend.

Car details:

DC2 VTIR, full tank of fuel minus ~2L, retains trims on doors/sides/boot, head unit and front/rear speakers in stock positions, all front carpet, dash etc.
Stock exhaust manifold and cat back, x force cannon style muffler.
Sprint Hart CP-F 15 inch rims / nitto 205/50R15 NT01's (14.1kg ea, yet to weigh the stock fat fives but the space saver weighed 11.1kg so a bit more than that I would think)
Drivers seat Bride recliner copy (haven't weighed this, doesn't feel lighter than stock though), stock passenger seat
Exedy lightweight flywheel (4.4kg vs stock 8.18kg)
CTR N1 crank pulley
280mm front brake upgrade - 4 stud pattern, didn't weigh these when installed but heavier than stock 262mm setup.

Removed:
P/S
A/C (still has evaporator - anyone know how much this weighs?)
Rear Seat & seatbelts
Rear Wiper
All boot carpet, spare tyre, cover, jack
intake resonator box in front of drivers side wheel, rest of stock intake kept.

Added:
280mm front brakes
19 row oil cooler plus AN10 lines/remote filter mount.
1kg fire extinguisher and bracket
Rear boot brace
Beaks bar
4 point 3 inch harness

FINAL WEIGHT - 1124kg (includes gear bag with helmet, race suit, shoes jacket approx 6kg total).

Not too bad, based on initial cvm of 1176kg. None of the removals were particularly difficult, would like to get under 1100kg.

Will remove more for next event - rear speakers and antenna first off, sound deadening if I can be bothered. Car is mainly used for track and not daily driven.

[bennjamin]

rc_ IMO

either go all out cause race car or dont bother.
Sacrificing the comforts of a daily driven car isnt worth 1/10th of a second. Make more power or play with gearing if you want proper results :)

I see what you're saying...but my car isn't daily driven. It pretty much only gets driven on the road to the track and back, occasionally a mountain run to test changes.

In terms of weight reduction, I would say 50kg is definitely significant on the track, i noticed a big difference from first time out dead stock to next time with A/C & P/S removed and rear seat etc.

Also it is FREE to remove things you don't need!!

Other performance upgrades are in planning, but they have to wait for funds. I just blew this years budget with an engine rebuild so no more major parts for a while.

[bennjamin]

Having been down the same route with alittle EG and a B series motor I found the only real difference in performance was from removing both the AC and PS. Everything else is tiny and not noticeable.

[Vvvtec]

my car feels faster with rear seats removed and washer bottle nearly empty

[u mad?]

Obviously little things on there own don't make fuk all difference, but a whole lot of little things add up.

Last time i weighed my dc2r it was under 1050 with no fuel

Would be maybe 1030 after taking more shit out atm

Take a dump before re weighing will make a difference.
