this ROXXXXXXXXX, keep going guys, but i will Never Ever travel w/o a handgun, so accept that weight

gtdrei

Stock headers weigh more than most of the aftermarket headers, no ? Anyone got those numbers ?

Robin

DCLee

That's a good point about the race headers-- will weigh when I swap out the stockers for longtube headers. Got to be some weight-saving there.

Re Watt: Perhaps if you left the ammo-belt at home?...

Few items that come to mind not already mentioned with approx. weights

* Sparco seats with fixed mount 22lbs (20lbs with CF shell)
* delete entire glovebox (-8lbs?)
* passenger side airbag -10lbs
* delete cupholder (metal part) -2lbs
* delete visors (-2lbs ?)
* Titanium bolts -- they look cool anyway
* Ciara CD (add 1oz)
* delete gun rack -- oh that was already mentioned

Sorry, but I just can't remove my Earnhardt stickers...probably cost me a .01 sec a lap!! Damn... and BTW, I found a titanium gun rack on some NASCAB site- that should save some weight...

GTGTGT

Where can one purchase the titanum wheel bolts? What is the cost - that is an easy change!

Mikey

Oh yea of course the CF wing ... 4lbs vs 8lbs sotck.
The Titanium bolts DO NOT save 8lbs ... the savings is may be 1-2lbs. They sure are pretty. Cost is about $500 per set.

NJ-GT

Who sell those? The BBS Wheels need longer bolts or studs and they are heavy.

We need the following weight figures:

- Catalic Converter
- Headers
- Rear Deck lid vs. Cup Car deck lid
- Stock Airbox vs. Cup Car cone filter
- Stock front and rear bumper vs. Cup car
- Stock transmission vs. Cup Car transmission
- A/C delete option
- rear carpeting
- Stock Steeting wheel with Airbag vs. Cup Car Steering Wheel
- Stock doors vs. RUF CF doors
- Rear side windows and vs. Cup Car Lexan
- Rear window vs GT3RS lexan
- stock wheel carriers and hub vs. GT3RS version
- Trunk and rear deck lid support shocks

Stock wheels weigh 48lbs. front and 55 lbs rear. I weighed these last week.
WOW!!! Was that both together to get the F & R totals, or with tires on?
