Evo 8 and 9 weight reduction thread

[dsmrunnah]

I had a chance to weigh my street and slick setup when changing out tires.

Stock Evo 8 Enkeis w/ 235/45 Falkens = 48lbs
Stock Evo 8 Enkeis w/ Motorcycle Slicks = 35lbs
Motorcycle Slicks alone = 14lbs
Konig Daylites (17x7) w/ MT Slick =30lbs

What size of spacer are you using with the daylites in the front?

[06MREvo]

awesome...i like this thread a lot...a bunch of good info in here...

[03whitegsr]

Does anybody have the weight on the front EVO 8 cloth seats with sliders and the front EVO 8 seatbelts with the explosive charge?

[yellowevo42]

i may be able to get you weight soon of just the seats, i might be taking mine out saturday to try n fix the seats

[03whitegsr]

Cool, the seats didn't seem terribly heavy when I had them out but I didn't have a scale to weigh them to find out. But with 12 pound seats being fairly reasonable in price, it's worth looking into.

The seatbelt assembly has me quite curious though as it looked pretty beefy and I've been told it has an explosive charge in it similar to an airbag in weight.

my driver seat is worn out, i have no idea what im going to do, i def need something that reclines if i cant fix this seat.. im going to take it down the way here for an estimate to fix it.

20mm.

Lowest offset I could find was 40+

Here are a few things from today:

Seibon carbon fiber trunk ($539 shipped from CVRmotorsports) - 12 pounds

AC compressor, condensor, fan, bolts, bracket, lines from under hood & firewall padding/cover - 39.x pounds

Evo 9 Enkei OEM rims & BFGoodrich 225/45/17 drag radials (60% tread life) - 43.4 pounds

NEW Enkei RPF1s (black) 18 x 8.5 & Mickey Thompson 245/45/18 drag radials (NEW) - 43.3 pounds

does anyone know how much the big cross bar under the dash weighs? if its heavy what is it made of? and is anyone interesting in having one that is light weight made???? or what other options do we have for this thing.

very tempting to pull the a/c...

any weights on the abs delete?

[dd_man]

Not sure if anyone mentioned this but, I just put coilovers on it it saved me about 30 pounds.

any weights on the abs delete?

STM sells a kit and they claim around 15LBS. I would like to do this but im waiting to see if the ecu editors can somehow keep the ABS light off so us street people can get through inspection.

[mullen]

ya i would like to do this but ill have to wait, trying to lighten this beast up

It's pretty damn heavy. It's steel.
Hydroformed into a taper, about 2.5" in diameter on the driver's side, 1.5" diameter on the passeneger's side. I didn't measure it, just a rough estimate.

It has brackets for the steering column and dash supports. Overall, I would think 20 pounds, possibly more. Hard to say though as the wiring harness is hooked on to it in numerous places and the harness isn't all that light either. It appears to be a structural part of the car though. Making it lighter could have chassis stiffness downfalls as hydroformed steel often gives very good strength (and stiffness) to weight ratios.

If you were caging the car, I'd definitely remove it and built it into the cage, along with a light weight steering column. For a "street car" it may be hard to drop weight with this piece while retaining chassis stiffness.

Or safety. If you plan on driving on the street thats just a very bad idea. It provides about 50% of the cars front end protection in head on collisions. Mainly keeping the motor out of your lap.

I did weigh my old wheel setup.

Rota P45R 18x9.5 w/ 265/35/18 fuzion ZRi's 50lbs per corner

[03whitegsr]

Any basis for that claim of 50% of the protection?

I would think the double wall firewall and multiple crush zones have a signifigant impact on crash protection. By saying it was a structural component though safety was also #2 on the list. If you are caging the car though, I think you could make a dramatically lighter bar that would still offer lots of protection.

[evodan2008]

yea the car is in line for a 6 pnt cage. i wanted to get a bar and make my own light weight one. using chromoly. or just modify the stock one. i have a few idea's in my crazy head of mine. to make one and build it into the cage would be a good idea for a car getting a full blown cage. but on a street car i think id be adding more weight to make that happen.
