weight reduction
im off to the scales tonight and i was wondering if there was any more weight i could take out... like sound deadning i might have missed... i got all the stuff out of the back and the wood there... spare.. jack.. and the usual engien stuff... is there any more sound stuff hideing on me... my car weighed 1130kg last time i weighed it... and i believemy buddys was 1030kg... and he took 150lbs more out of it today.. i need to catch up, i know i will not get that light but what else can i take out? im off soon so any help quick would be great! thanks

Sheez, that's fricken' light!  Care to tell us what exactly did you do to get the weight down that low?  I would think getting it down to about 2500# would be a major pain!  2500# = ~1136kg.

Ok inside your doors are a anti-crash bars
wieghts like 30+ pounds x2
lighter rims then the stock ones
there you could save some wieght
plastic smaller gas tank
fiberglass hood
take out the metal bumpers and just leave the covers

yea
well you know the bumper covers are made of plastic urethane
under those are the METAL (heavy) Bumper's
Take out the bumpers and put the covers back on and no one can tell you dont have bumpers
except when you get into an accident
then you can tell

Have you removed the most heaviest parts of the car???
Such as:
I will remove power steering, stereo/speakers/cables, A/C/compressors, resonator/air box and replace it with CAI, rear seats, trunk struts, washer fluid pump and bootle, center console.

I'd only worry about the bumper skin deforming at speed, without the metal support. Haven't seen one without the metal underneath, so it may not be an issue.

I wouldn't do much to the doors, they are heavy, but unless you're prepared to remove the windows entirely, you're pretty much stuck with it. You could use a hole saw and drill some of the metal out, I suppose, but for the effort involved, probably not worth it.
Lexan rear hatch might be worthwhile. Being on the rear, it won't get pitted like a windshield would, it's lightweight, and if you take care of it, it'll be just fine. Kinda pricey though. Mazda Comp sells them, if you're interested.

Edit:
Found the article from May 2002 SCC
The most modern of the exterior details is the scratch-resistant Lexan right rear window. Lexan windows on rally cars are usually scratched to the verge of opacity since the simple act of wiping dirt from them will leave permanent scars. The Percy's Speedglass used on the EVO II, however, has a scratch-resistant coating hard enough to withstand steel wool. The lightweight right rear window serves both as a weight-saving device and....

2500 lbs seems a bit too low to me... especially considering the small amount of stuff removed...

I am deciding wether I should get the hand roll window RX-7 or the one with power windows.
For some stange reason, the one with power windows is a much better deal........
Anyone knows if I can replace the stock power windows with a manual unit?
