Instead of stripping, you could fill the car with a load of helium balloons !!! Should save some weight and if there's a leakage in the car, you'll have a laff when someone talks....

Removed carbon canister a year ago, as I needed the space for a RCM cone filter. No ill effects / fuel smell and fuel economy has never been better - but I guess that is down to the fuelmap

Ive got an 03 plate wrx, its going to be a road going track car.
Removed: carpet, sound deadening, bulkhead sound proofing,air con, airbags and wiring, spare wheel jack etc, many unneeded brackets/long bolts, rear spoiler, side skirts.
realistic weight saving around 45kg
Fitted: lighter DTM mirrors, carbon bonnet
Realistic weight saving 8kg
When funds allow il fit: racing battery,Lighter front seats, glass fiber boot lid, spec c manual windows

Interesting thread.
For a track car, I reckon you can save quite a bit of weight by cleaning up the wiring, as half the wires won't be needed on a track day car.
I'm also about to attack the rear doors with the old plasma cutter, and who needs a spare wheel well?
One thing I wonder is how much of the inner skins I can take off the front doors without compromisng safety unduly? I've got a full welded in cage with door crosses etc, so I don't think safety would be compromised, but I'd welcome input on this subject.

I'm interested to see what you guys have got your car weight down to on the newage models, and what you started with. Mine is a UK blobeye, I am down to 1266kg fully wet with driver when stripped out, and slightly more now with some interior back in.

It would be good to weigh my car, changed the rear seats to spec-c ones, prodrive fronts, all airbags gone and most of the aircon system - trying to keep it useable as a daily drive but shedding anything that is non-essential

Sry, can't tell you that. Chevron keep those types of things to themselves. My car is used as a development car for them, so quite a bit is stuff is their knowledge only. Like some of the engine work, the TMIC, the geometry setup they use, diff setup, etc.
Total saving was a lot though. In some cases it was 10 - 20kgs at a time

I'm guessing WRX? Does that include rotated pipework or is the turbo standard position?
It's worth having a search through the forums because some of the claimed weights on newage cars are, frankly, laughable. There's more than one "track prepared" UK newage STi out there claiming circa 1300kgs (and less in some cases) yet still managing to sport a Max Power bodykit, bling alloys, gazillion point cage and more chintz than you'd find in a McDonald's car park on a Saturday night.
My UK Hawk STi currently weighs in at a little over 1300kgs + fuel + driver. What I've discovered is there is a fine line between weight saving and compromising the car as an overall package. I reckon I could go out to my car tomorrow morning and take 30kg out of it by lunchtime but I'm not convinced the benefits would outweigh the "costs" (I've got TWO fire extinguishers in it for a start) so for me weight saving is more of a gradual improvement over time.

Yeah, it took Chevron many months of prep to establish what could come out and what had to stay. The concern for me was when removing chuncks of metal that safety would be an issue in a collision. A lot of it was differences between the UK variant and the JDM RA R. I'll have to ask them exactly what they did.
Not a WRX, it's a first gen blobeye STI. Standard position turbo. It would be heavier now as I have put on some weight. I was less than 70kgs when I was weighed in :-)
Next step would be carbon or glassfibre doors and roof, but adding the cage that would be required as a result more or less negates the lightweight doors and roof, and a well welded in cage is 65 - 70 kgs.
As you say it's all a compromise, and at the moment it's running heavy as I don't want all the road or rear end noise from the fuel system when I drive to work so the rear seats and carpets are back in. But even in it's present state it blows away anything else I have driven.

My new age track car weighs 1320kgs without driver. I'm planning on getting this down to below 1200kgs by fitting fiberglass doors with plastic glass,light wieght alternator,lightwieght mirrors, fiberglass boot without wing and lighter intercooler.
