2. Tein double adjustable aluminum coil overs 46 lbs ''saves 19lbs over stock''
3. HKS Hypermax weighs 46.8 lbs ''saves 18.2 lbs over stock''
4. Tein Super Street coil overs weighs 52 lbs ''saves 13 lbs over stock''
5. MAGEN Racing coil overs ''street'' weighs 45 lbs ''saves 20 lbs over stock suspension''

DMS 50 mm suspension 58.2 pounds
Stock EVO suspension, 64.6 pounds
Tein Super Streets, 52 pounds
Tein DBL adjustable aluminum, 46 pounds
Apexi N1's, 34 pounds (10 pounds ea. front and 7 pounds each rear)
Meagan Racing coil over 12.3# front, 8.6# rear
HKS Hypermax Front 13.7#, rear 9.8#
Apexi S1’s, 51 pounds, 15.2# front, 10.3# rear
D2’s, front 10.8 #, rear 7.5#

Has anybody else weighed the Apexi N1 coil overs? I believe those numbers came from David, and I don't think he was wrong, just hoping for some secondary validation.

I've been looking around a lot and those things are a LOT lighter then almost anything else out there. The swift springs drop another pound or two per corner too...

[mullen]

i just picked mine up today so ill see what i can do

[xcelr8]

Im about to scrape the entire undercoat off my 04. I may weigh it. Not sure if its already in here but all of the interior sound deadening weighed in at 22.4lbs

[03whitegsr]

Let us know how that goes. Sounds like a serious pain in the ass. At least the stuff inside of the car can just be frozen with dry ice and it pops right off in under 30 minutes.

Just FWIW though, I did find out, unintentionally, that gasoline strips that stuff off like nobodies business. Not the best clearner, but it did work well. I assume what is on the bottom of my car is factory anyway, it's softer then what is inside of the car and thinner. More like roofing tar.

I hope to one day just acid dip my evo to get all the seam sealer and undercoating off.

[evodan2008]

can anyone tell me if any of the aftermarket sway bars are lighter then stock? and if so what is the lightest one?

[David Buschur]

I just got a Hotchkis rear from Emery, amazing how light it is, 6.x pounds. I need to check on the front and see if it's lighter than stock too.

How does that compare to the OEM bar?

[David Buschur]

I have to check my notes at the shop but it's quite a bit lighter than stock and I've got some big ass after market bar on my car, so can't wait to swap mine!

[yellowevo42]

going to let u know dave that the front sway bar is a pain in the ass to install, but im sure you will manage.

[8thWonder]

I've got the Hotchkis rear on mine, which is very light compared to stock, but haven't done the front, because of that^^^.

[yellowevo42]

i have a godspeed rear sway bar here at my house that i havent installed yet but i weighed it and it came in at 5.6lbs... i have to re do it though to make sure im accurate

[Evilution09]

Does anyone know the weight of the Tanabe chromoly rear sway bar. I even called tanabe and for some reason they didnt know how much their own shit weighs.

[evodan2008]

no i dont. but the hot chicks ''or whatever its called'' from what i read is the lightest you can get.

[mullen]

Anyone know the weight of the stock evo 8 wheel without a tire? Im trying to decide if I should run these of buy a set of the rpf01 in the future for a roadcourse. Setup

19.7lbs a rim i believe. or its 21lbs. im pretty sure its 19.7 because the BBS rim is 17.7. the rpf1 is what 15 or 16lbs? do it.

[blackout]

I would have to agree with the rims being just a wee bit over 21 pounds from what I remember

[mullen]

Ya im debating on 17x8.5 +30 or 17x9 either way with stretched 235/45 kumho ecsta xs

[mullen]

I found it odd that the majority of bigger shops aren't running the carbon fiber driveshaft, what's up with this other than the price tag
