yeah...we already knew you didn't know what you were talking about!

CF doors will save over 100 lbs.

How could I forget my favorite mod...

My Craft Square mirrors.



Not only are these things disturbingly light weight but they give you a field of view that you wouldn't believe. There IS NO blindspot with these mirrors.

That's a mod worth doing for some one with composite work experience, good winter project when I get the garage organized + a compressor.

Are CF or fiber glass doors sold for the S2000?

[GChambers]

Yep, CF doors are sold by one of the JDM tuner shops. I think they are about $7000 for the set.

Hey Gus, you get the garage organized and I will supply the compressor. Lets make some carbon fiber stuff!

Just hope you don't get t-boned by a red-light runner w/ CF doors...I don't mind a little extra weight there for the additional safety on the street.

As easy as it is to spend a lot of money pursuing weight reduction, I'd just go w/ an Elise!

Why not just ditch the passenger seat altogether? while you're at it, you can also remove the seat belt and tensioner. also take out the crappy factory stereo and speakers. since you don't have a passenger, you can also remove the door trim on that side.

If you just want the car to be lighter, that is fine. But, most of us are cutting weight to compete in autocross or some other motorsports. Most class rules do not allow removing seats, seatbelts and interior pieces.

Get a header. The stock header, while very efficient, is very heavy as well. A Mugen, J's, Rick's or Toda header will lose about 10 lbs and maybe gain a few hp as well.

Get a set of 17in. Volk CE28Ns. These are absolutely THE BEST WHEELS FOR AN S2000. If anyone says differently, they are wrong. They are the right size, have the perfect offsets and look great. Most importantly, they are the lightest 17in wheel made for the car. They will save you about 4-5lbs of unsprung weight per corner with the right tires.

If you do not need it, get rid of the air conditioning. It is 40-50lbs.

The right exhaust could save you up to 45lbs if you don't mind a lot of noise. I briefly had a Magnaflow Titanium exhaust that weighed about 7lbs. It was loud as hell though. A Mugen exhaust weighs about 25lbs but is very quiet. Almost as quiet as stock. An Amuse Dual Titanium is a bit more expensive than the Mugen but reportedly gains a few more hp and is about 15lbs.

A cold air intake could also save you a few lbs. Most importantly, it will help eliminate the heat soak problem. On a hot day, my AEM V2 probably does not make much hp but it does an excellent job of drawing in cool air as opposed to the hot air from around the radiator.

You could also remove all of the trunk lining along with the tool kit. The trunk lining may weigh about 7-8lbs.

Also, consider getting a nice set of coilovers. Some are much lighter than stock. I am certain my Ground Control/Koni saves a few lbs per corner since the springs are about a third the size of the stock springs.

I, personally would not mess with relocating the battery. It is in a good place to start with. Also, if you relocate the battery, you are going to have to run a new battery cable. This is a very heavy wire so you will actually be adding weight to the car. If you do gut the air conditioning and don't add a stereo amp, you could replace the stock battery with a riding lawnmower battery. They are very cheap and weigh about half of what the stock battery weighs.

I could go on...

In the middle of fantasizing about the S2000 eventually being legal for a SoloII Street Touring class, I figured that I could easily get the car down to a very streetable 2550lbs with little problem and maybe under 2500lbs with some serious effort. With maybe a 10hp bump with all these mods and the lower curb weight, you could go from about 11.7lbs/hp to about 10lbs/hp.

Are the seats comfy?

Where are these aluminum parts you speak of??

[OVERSTEER]

Comptech wishbones.

[GChambers]

The asshats at the GFL on the "other site" have some light suspension pieces. But, buying them means dealing with those freaks.

If you are asking about the Mugen or Buddy Clubs, yes they are. If you are small enough to fit in them. I don't fit in the Mugens. I have not sat in the Buddy Clubs. There are many other light weight seats that will fit the car.
