Like title states, I am looking to shed about 100-200lbs off my daily driver Evo. Yes, I have searched and read countless weight savings threads on the forums - but I don't want a gutted race car - I am looking for real-life suggestions on how to put the "average Joe's" DD Evo on a budget diet - i.e. no magnesium wheels, AC delete, or carbon fiber doors please...

A couple things:

1) The front/rear crash beams need to stay - I occasionally drive my kids around...

2) Probably best to keep the spare + tools in my daily driver...

3) I will be keeping full interior (carpeting, seats, etc...)

4) I am looking for cost-effective part upgrades to accomplish my goal (i.e. mini battery is first on my list, lightweight wheels and rotors next)


Any suggestions are greatly appreciated...

 

1. you can try a titanium catback
2. lose some body weight - the most effective way

 

yeah, thanks... I've already been hardcore dieting for 5 months straight - still 230lbs - damn...

I think I will be purchasing the $60 Deka 11lb mini battery as posted in a recent thread here, and then making some no-frill DIY tray. That should save, what, like 25lbs from the best location possible - high, front, and driver's side.

Now I need to find another bang-for-the-buck mod like this...

 

I would reconsider removing the jack and tools and tire. I took mine out because I figured that I would never risk running on that tiny little spare. I'll just wait for AAA to pick me up. Instead of getting a mini-battery (terrible cold weather start-up) consider getting an approved sealed battery box and relocate the entire battery to the trunk. This will help with the front biased weight distribution as well as remove all that weight from the front. Also, like the above poster stated, a titanium cat-back or light weight SS cat-back would also help. Maybe also a hollow rear sway bar like the Hotchkiss piece.

 

When your getting lighter weight wheels make sure you get a good set of lugnuts like volk. You may think it doesn't make a difference but it does. It's less rotating mass too.

 

door bars, the undercoating on evos is like 40lbs, light weight battery, Ti exhaust, lighter wheels, rotors, sub woofer, aluminum or cf drive shaft.

 

I agree to remove the spare and the tools. Go with titanium parts if possible. CF hood, and trunk.

 

yeah, I should be used to not having a spare as my last car (M3) came from the factory without one - they just give you a AAA card instead...

Of course, maybe I should start looking for a "lightweight" spare...

Titanium exhausts are just too damn $$$ for me to justify right now.

All right, so if I do the mini-battery + spare/tools delete, I'm looking at like 60lbs saved?

 

Take off ur wind shield ur dog and kids will love it lol J/J. Really tho make sure that u dont have ur cat and rez on exhaust not sure what kinda exhaust u have but full titanium from front to back would help and to dump ur spare plus a carbon fiber hood would do the trick not sure what u do and dont allready have tho just some ideas good luck.

 

anyone know an efficient way to remove the undercoating?

 

1) CF Trunk
2) Lighter Wheels
3) Mini Battery

And the most obvious...Buy Mods to replace stock parts that are lighter.

With that said though, thats all i can think of off the top of my head with your "restrictions." If you plan to go to the track i would remove the tools and spare though...Don't bother getting a cf hood cause it's not gonna be worth it. Some CF hoods are heavier then the stock one. G/L

Edit: Idk why people say get a cf hood cayuse it's aluminum...Literally some CF hoods are heavier then stock!

 

Why do you want to keep the crash beams on? From what I heard there only good for low impact speeds, i.e. 5 mph or less.

Any who, the mini-battery and spare should save you a lot of weight. You'll probably notice the biggest difference once you get light-weight wheels and rotors because of less rotating mass. Carbon fiber roof by AMS could net you a couple more pounds. Maybe take the carpet out of the trunk even though it won't weigh that much. And removing the rear windshield wiper and reservoir.

 

My guess would be some type of abrasive solvent and scraping.

 

Some quality coilovers can also save some weight over stock.

Watch out for CF hoods. Unless they are high quality they will not save you any weight as the stock hood is already aluminum.

As was mentioned wheels and rotors can really remove some weight - not to mention that it is also unsprung rotational mass.

You might consider seats if you can find a reasonable compromise. The stock seats are quite heavy -- granted a full race seat is terrible in a DD.

Good luck -- this task will not be easy.

 

Guys, thanks for all the responses - I knew by posting this thread that I would get some answers that I never even thought of...

I would assume the underside coating helps tone down my exhaust, so I'll probably keep it for now.

I don't know anything about how well the front/rear crash bars work, but I would never forgive myself if anything happened to my two little girls in the back seat, all because I wanted to shave a few pounds off my car...

Ok, so the plan so far is:

1) Mini-battery
2) Spare tire/tools delete
3) Lightweight wheels/rotors
4) CF trunk
5) Lightweight coilovers
6) Rear wiper/reservoir delete

Any more suggestions?
