#99684 Grab handles, mudflaps, glovebox, audio, bonnet sound deadening pad if you have one, lightweight trailing arms (Just ordered some from ksport - £85)... that's off the top of my head, there'll be plenty more I'm sure.

#99723 im keeping most of the interior in tacked jsut making it lighter as its a daily driver :) the trailing arms sound a sweet mod :)

#99776 How about the blower motor, rear speakers, intake manifold brace, ECU bracket, knee bolster, and front and rear bumper supports?

#99948 I've been thinking about weight reduction in general recently, more specifically for the people around who say "it'll make you faster".

Lets just analyse for a second.

A UK VTi hatchback weighs 1080kg. Book time 0-60mph is what 7.2s? Not bad.

Compare and contrast with an EM1. Same engine, heavier car. 1250kg to be exact making it a whopping 170kg of difference. 0-60mph? 7.9s.

Wow, what a difference. 0.7s give or take in acceleration, from losing 170kg. Epic.

Now, I know that weight reduction has other benefits. Slightly reduced braking distances, teeny bit more nimble and easier to handle as you have less weight to transfer, higher MPG (quite possibly the most boring topic ever to grace the internet) blah blah blah

But, consider that in a vast majority of cars you'll struggle to lose 50kg or so if that without being really stupid. Is it honestly worth all the effort some go to for supposedly 'free performance'?

Personally for all the effort I just put in I'd want significantly more gains. And consider what you have to put up with, increased noise levels, less comfort...

Worth it? hmmm I'm not so sure. Yeah, if you're building a track weapon go nuts, strip the lot out. If you're not planning on hitting the track that often though and drive on the roads fairly regularly is there much point? Me, I'm gonna say no. I'll be very happy staying cool with my 'heavy' A/C, comfortable with having a full interior and somewhat reduced noise levels.

Just thought I'd throw a curve ball in the mix.

#99968 I agree. I wont dispose of my creature comforts in a car that is used primarily to get to work and back. But some things serve no real purpose (not to me at least) and are so effortless to remove, that I'll just remove them.

Aerodynamics prove much more effective. For instance, you can get a front lip spoiler from an Si/VX, a VX rear diffuser, and an AC delete (or fashion a grill block) and it will have much more impact on the quarter mile times and FE than weight reduction.

#99969 My view is there's different ways of doing it dependant on your overall goal, and how hardcore you like your car. Some examples of no/low cost weight reductions:

Stock look
Lose air con/spare wheel, tools and jack, replaced with inflator/sealer, lightweight trailing arms/light weight battery relocated in boot.
Pro - Retain full interior/stock image. Substantial weight drop/no increase in noise levels or increase in driving effort.
Con - Removal of air con may be an issue if you really need it.

Stock look, part stripped
As above with sound deadening removed in part or in full/ABS delete/PAS delete.
Pro - Retains a full interior/stock image. Further substantial weight drop/performance increase.
Con - Dependant on the extent of what's removed day to day drivability may suffer significantly.

Fully stripped
As above with rear interior/carpets/trims/audio/ecltric windows/sunroof/etc removed.
Pro - Performance benefit.
Con - Undrivable for most people on a daily basis. Best left for the track or for the hardcore road driven brigade only.


Personally, I never had air con or ABS anyway, and had only intended to go as far as the "Stock look" I described, but after driving without the rear interior in for a couple of days since not bothering to put it back in yet and feeling the benefit to how the car reacts, I've now decided to lose the rear seats but make a matching carpeted flat floor in the back. Most people can find a degree of weight reduction on a daily driver they're happy with, and it all helps.

#100494 OEM VX rear diffuser costs like $35 from the dealer.

#100549 i was thinking of making summink like this

wouldnt be to hard to get some alloy bent like that make sure its perfectly flat when mounted and angle very slowly.

and if i want to be a right pain in the ass on strip get soem gaffa tape and put it over all th eholes in the body work haahha

but back to the weight reduction the reason its soo important to me is saved fuel quicker cornering over all better car unless its wet ;)

#102255 i was wondering is there any direct swaps for no power steering rack ?? as i have done the cut and loop pipes before but i was wondering if theres a direct swap

#102267 Manual steering Civics are more common than power steering Civics. Only the automatics, EX's, and Si's had power steering. Possibly all the four doors, I'm not sure.

Besides the rack and the pinch bolt, you also need the crossmember. The mounts are different.

You dont happen to know the part number do you..?

#102276 i ahve a manual rack and noticed this in my integra but also the splines are too small to fit in. i was thinking of just making a plate on the cross member to fit it but the conection sides didnt fit either.

the car im getting is an lsi duel poitn injection fairly light weight but i want to make it even lighter. have you got any info/pics on how the manual rack would have to be fitted
