Odyssey PC680 Lightweight Battery

Another really easy weight loss tip: drain all of your windshield washer fluid then add back just a little (in case you need it). Might be worth a good 8 lbs of weight savings or so...not really sure. OR, just remove that huge washer fluid reservoir altogether!

I calculated my weight savings at around 80 lbs...and that includes new battery, no spare (keeping the subwoofer though), lighter tires, HF cats, lighter exhaust....but I am going to add an oil cooler (probably +8 lbs). Realistically, I'll also be running about 1/2 tank of gas...so I HOPE my total weight will be down around 3230 (I have touring with sport pckg).

Started preparations for the upcoming time attack this weekend and weighed a lot more stock pieces. All of these pieces were removed in approx. 10 min. and can just as easily be put back once you are done with the track!

Stock lug nuts = 3 lbs. Muteki open end lugs = 1 lb. The Muteki's are not recommended for the stock wheels though.

I have to disagree here. Coming from an S2K where weight reduction is crucial, I think one member put it best. He also happens to be one of the top S2000 drivers in the US.

If you're building a full race car then yes. Most of us on here wont be trying 10 different sets of springs until we get the right set that offsets weight balance. The purpose of my personal build is to stay within the boundaries of most enthusiast's budget and capabilites.

Honestly... every pound you save on a 3000lb car on the wheels is tantamount to about 1whp. Going from stock 19's to Volk CE's on my G35 made a bigger difference in speed than all the intake mods I ever did... Just food for thought...

hmm...that's rotational mass on the wheels. They are talking about sprung weight...also your 1whp/lb is not all that accurate. Taking 40 pounds off the car doesn't feel like adding 40whp. Maybe more like .25whp/1lb I would believe.

Well I mean... taking 1lb off the cars rotational mass should be equivalent to about 1whp no?

Just out of curiosity, has anyone taken out any of the extra safety requirements such as the air bags by the doors and whatnot?

I'm planning on it... will prob have it done, so I don't have to reset computers and don't want to take the chance that I deploy them... if anyone wants to see what they look like, i've got pics up here, about 1/3 of way down the page

Did anyone weigh the stock intake compared to the Stillen long tube Gen 3?

I'm liking this thread.. the most relevant thread in the whole world..

I have an idea. In the S2000's we were able to vent the hood. By venting I mean cutting the hood itself around the ribs and putting a mesh grill. Not only would this reduce weight but also release excess engine bay heat. Here's what I mean.

S2000 Forums -> The Vented Hood Club

I actually have a guy on LI who does this professionally. I had it done on my S and it worked and looked great.

All we have to do on this car to vent is eliminate the wiper assembly and plastic cover... it opens up about a 2-3 inch gap next to the windshield and creates a lot of airflow
