Can you explain this further - carbon fiber hoods weigh more then OEM? I know OEM is light...but lighter then carbon fiber?

 

It's a good mod if you sit in traffic. Sorry to disappoint you, EJ.


PS. I can't see pics here at work, but did re-read the entire DIY thread as I remembered Mike had something to say about it.

 

Not all weigh more than stock, however, most of us can't afford those. Yes, the crap that is out there weighs more than stock because you're usually getting carbon over fiberglass which is then clearcoated. Replacing the stock hood with most CF hoods for the purpose of weight savings is void of desired results.

Dry carbon hoods would offer some weight savings. The hood would be lighter than stock... and so would your wallet.

Replacing a stock hood in favor of a vented one makes sense.

 

we're talking about those $600 ones made by seibon and the like

 

im glad this poped up... i planned on doing this to my OEM hood. and now I have a OEM hood to practice on.

 

This is how it is with STIs too, its mainly for looks to replace the stock hood.

I may replace the oem hood with carbon fiber vented one because I think it looks cool on Rio Yellow...In other news I wish it was easier for the s2000 to lose weight

 

single exhaust, hardtop with removed soft top, frame and motors, light weight 16in wheels. like 60+ lbs less.

 

You're correct; it's not easy to lose weight on the S. EJ was on the right track.

Replacing the enitre exhaust(header, cat, exhaust) nets a potentially significant loss. When I ran the Rick's header and the T1R 70RT, I saved at least 60 lbs. The downside of this(not applicable on the street) is that weight is removed from a relatively low point on the car, thereby raising the car's center of gravity.

Lightweight battery. For approx. $175, you can have a 14lbs battery. That may be approximately 10lbs saved.

The softtop assembly is approximately 70-75lbs. OEM hardtop weighs about 44 lbs. You save 30lbs and decrease drag. My current hardtop weighed in near the 15-pound mark. Unfortunately it is a little heavier now that I repaired it.

Trunklid is not aluminum like the hood. Weight can be saved there even with pseudo-CF ones.

Wheels are a great place to shave weight, but most times, it'll cost you.

Airbags are heavier than I thought, but most on here street their cars. I DO NOT recommend removing your airbags if you drive on the street. It's illegal.

Spare tire/tools.

Seats.

Carpet.

Stereo/speakers.

 

How about light weight rotors and brake kits? That has to be a big increase in performance for driving... - less weight to turn

 

Lighter weight calipers- yes. Two-piece rotors = lighter. Yes.

The stock braking system on the S2000 is phenomenal and nearly maintenance free. Stoptech/Wilwood/etc. haven't really panned out at the track or rules dictate otherwise.

I guess it comes down to how one plans to use the car and how much one can do to the car themselves. I do most of my own stuff, and stock rotors/calipers are the ticket for me. Just upgrade fluid and pads and you have a track setup.

If you're looking for 1/4-mile, then the high-dollar kits may be right for you.
