Would like to hear suggesrions too, I reckon you can shed some weight of wiring without removing aall thats necesary... im at that weight too but havent got a cage in, also havent done doors/windows and bucket seats.
Removed rear wiper?
Theres got to be some weight reduction on the steering column..
Rims..
What about changing the firewall to fiberglas?
I did some good trimming on the front crash bar...

Not much if any. You still have a big lump of steel for a manifold, turbo is much bigger but weighs a bit less than the twins put together, but then there is the extra weight of a big/2 small external gates and extra exhaust plumbing.
The only thing you have less of is the plastic and rubber intake pipes and mafs.

Put some carbon wheels on
TBH; I think you'll be hard pressed to loose another 50kg without it turning out mega-expensive...

wiring loom is a stand out area for improvement - must have a lot of unused cables in there now.

Its crazy - the other car (Impreza coupe) weight 1187 in race trim with full metal doors, CDS cage and electric windows/mirrors hehe

Adam,

I think that the steering column would be a good place to loose some weight, it's such a safety critical item that any modification would require careful planning.

Cheers

Hugh

Is the roof double skinned?
Alloy engine mounts and gearbox mounts/braces?
What anti roll bars are you running? I was reading a thread the other day about how some are much heavier than others. Will obviously still need to do the job though.
Carbon prop? Even just a one piece steel prop is quite a bit lighter than stock I believe.

Buy a really good hole saw as well lol

Would have decent weight to lose with a good internal gate setup like the EFRs, you'd also get to dump your bovs (and return pipe if still there)

I've got a set pf Cusco anti-roll bars in the corner of my kitchen at the moment so I can weigh them for anyone interested.

They're tubular rather than solid like the Whitelines and non-adjustable so not sure how you'd compare stifness. Whiteline only quote a packaged weight on their website unfortunately so someone will have to weigh some Whiteline bars to get an accurate weight for them.

Whiteline
Front 22mm
Rear 24mm

Cusco
Front 24mm 2.7kg
Rear 30mm 4kg

If anyone needs a front Cusco bar by the way then I have an unused front for a R32 GT-R which I keep meaning to advertise. Basically I bought a front bar and then I came across a pair of secondhand bars which I'm going to re-furbish and use on mine.

Cheers

Stu

any info (links / prices) on a carbon prop?

I'd imagine them to be about £1000 - which in the scheme of things doesnt float :lol: I'd rather spend that on fresh tyres.

Carbon props are very expensive.
Could get you current 2-piece prop converted to one-piece steel?
I think it cuts about 6kg off and gets rid of the sloppy rubber bush in the middle, bit harsh for daily drivers but beneficial for track cars. I think Bruce-m on skylineowners has one

Not made any changes, but a lightweight column has been a topic for conversation with Rod.

No conclusion yet though

the one area i dont like removing weight from is the rear of the car as it makes it even lighter than the heavy front, the engine bay is where you want to take the most weight from but you can only remove so much i know!!!!

Weigh the wing separately, it is surprisingly heavy!
