Heres my weight savings so far,
Odyssey battery saved 20lbs
removed spare/jack/tools saved 42lbs
titanium lugnuts from japan saved 4lbs (1lbsx4)
thats a permanent 66lbs, there is also draining most of your windshield washer fluid, and racing with 3/8 to 1/4 tank of gas.

While racing it's not hard to drain a full tank to empty in about 35 laps. 5 mpg X 14 gallons at 2 miles per lap.
So less fuel is not a valid weight savings when racing.
Maybe for shifty shifty stuff or a 60second autocross.

For anyone who questions the benefit of weight reduction.
Fill the back seat up with 300 lbs of rocks.
(or better yet a few passengers, 2 if their big ugly dudes, 3 if they are sweet hunnies you picked up with your phat EVO ride, you'll have to let one ride up front, or all 3 if your that good)
And drive around
If you can't notice a performance difference, I'd be surprised.
More noticeable with the fat dudes or the rocks, cause you'll have less distraction, but not as much fun.
Then just think if you could chop 300 more lbs you would have similar results.

a further extreme would be a motorcycle.
Its amazing what can be done with a whole lot less power because of the almost 3000 lb weight reduction.
No if only motorcycles performance wasent limited by traction or center of gravity issues.
That and you cant get all 3 hunnies on back.

Shifter Karts give one of the best examples. 25 HP? BAH right?
Well in a 225 lb sled at 1 inches off the ground you can hit 120 mph faster than most any street legal car and run 1.3gs around corners all at 50 mpg!

I broke this down as follows:
Enkei 17x8 RPF1 wheels with Hoosier 245/40ZR17 tires, secured with Zenki forged aluminum lug nuts. About 10 pounds at each corner. 40 pounds total reduction.
Removal of spare tire, jack, related tools, and floor mats. About 25 pounds total reduction.
Running with just over 1/4 tank of fuel. About 60 pounds total reduction.

The rest sounds great.

Since a gallon of liquid weighs roughly 8lbs, i usually only go to the track (1/4 or autox) with 1/4 to 3/8 tank, but my friends and i usually bring a few 5 gallon containers with gas. Just a cheap way of weight savings, afterall racing with 5 gallons of gas in the car instead of 14 gallons saves about 60lbs+. I was also looking into titanium bolts for most of the car as that sounds interesting, anyone know where to get them?

The aluminum nuts had very little tolerance for repeated use or overtightening.

Here's the nuts (and the supplier, Mach V) than I have: http://www.machv.com/forallugnut.html
That page states:
Note: These lugs are made of extremely strong high-strength forged aluminum, but they can still be damaged by impact tools. Use ONLY hand tools to tighten or remove the fasteners.

BUMP for a super old yet very informative/useful thread.
I am going to list down the stock weight parts that are featured in an article in Lancer Evo Magazine Vol. 17. Weights are originally listed in kilograms, I will be using conversion rate of 2.2
Oh and one more thing, this is based on a JDM Evo 8. Some things may differ to USDM, I can't verify because I don't have USDM Evo.
STOCK PARTS WEIGHT:
- Carpet (total front and rear) 3.0kg 6.6lbs
- Wooden boot cover 2.1kg 4.62lbs
- Trunk carpet 0.9kg 1.98lbs
- Entire rear seat 10.8kg 23.76lbs
- Front seat, each 14.9kg 32.78lbs
- Spare tire 14.3kg 31.46lbs
- Jack and tools 2.9kg 6.38lbs
- Full rear windshield wiper fluid tank 3.8kg 8.36lbs
If you do all of the above (i.e. take everything out, including the passenger seat) it will add to 52.7kg or 115.94lbs.
OTHER STOCK PARTS:
- JDM front bumper (no support beam) 7.9kg 17.38lbs
- Trunk (possibly with the wing) 9.5kg 20.9lbs
- Front strut tower bar 3.3kg 7.26lbs
- Catback exhaust 17.2kg 37.84lbs
- Bonnet 7.8kg 17.16lbs
- Wheel with tire 20.5kg 45.1lbs
- Radiator 4.5kg 9.9lbs
- Intercooler 4.2kg 9.24lbs
- Oil cooler core 1.4kg 3.08lbs
Next I am listing down the AFTERMARKET PARTS that replace the list above:
- Stillway front bumper (no support beam) 6.9kg 15.18lbs
- C-West carbon trunk (without wing) 4.8kg 10.56lbs
- ARC titanium front strut tower bar 1.8kg 3.96lbs
- ARC titanium catback exhaust 5.3kg 11.66lbs
- C-West carbon bonnet 6.2kg 13.64lbs
- Work Emotion wheel with tire 17.1kg 37.62lbs
- ARC radiator 5.8kg 12.76lbs (heavier than stock)
- ARC intercooler 6.0kg 13.2lbs (heavier)
- ARC oil cooler core 1.5kg 3.3lbs (heavier)
Once again I repeat these are straight off a magazine. If anyone feels the info is inaccurate kindly chime in. I have only verified the rear seat with a digital weighing scale.
