Default Spec C - why so light??

I understand that the spec c Hawkeye is 90kg lighter than the type uk, how does itamage this?

I know in general it has lighter panels an less sound deadening but does anyone know the details of all the parts that are different and how much each part saves?

I'm looking for a few ideas to lighten the Hawkeye and I figure this is a good place to start.

I also noticed the wrx is around 90kg lighter, how come??

Get over to the type-ra.co.uk site loads of info on there, but basically light weight glass, panels, carpet, stripped out boot, lightweight rear seats etc....

Lightweight glass and panels ???

Thought they were Subaru myths. Well on the classic they are anyway.

I believe removing the spare wheel, jack and tool kit saves about 54kg. A can of tyre weld is much lighter.
If you really want to save weight then remove the air-con, fit titanium exhaust and carbon fibre rear spoiler.

Boot lid, roof skin, and glass are definitely lightweight, spec c's don't come with an STi spoiler just the low level wrx one, also lightweight battery and if you get the BBS magnesium wheels they are even lighter than the standard enkai ones

To be honest i have never bothered to weigh it but a bloke at santa pod with identical car claimed he did weigh it. Thinking about it 54kg does seem a bit lumpy as that's like 2 sacks of spuds. It is surprising how heavy the space saver is though.

Mainly the glass, less paint, roof skin, light weight carpet, smaller a/c pump, redesigned front subframe, no side impact bars, no deadlocks, less switches, less electrics, smaller battery, smaller fuel tank etc.
All those small things add up

Sound deadening alone adds up to 25kg. The spec c also uses a different AC unit which is lighter.

Anyone know how much lighter the BBS wheels are than the standard enkeis?

Anyone have an itemised list of all the parts and their respective weights? Would be interested to see that.

For example, how much weight can really be saved by thinner glass and lightweight panels?!

There are no lightweight panels except the roof, the 17x7.5 BBS come in just under 8kg, which is light considering a similar sti one is a good couple of kg heavier.

Alloy bootlid saves a bit then the battery, lack of front crash protection u frame, sound deadening removed, thinner roof skin, thinner glass, no underseal, no passenger sunvisor, no boot release, no boot trim, lighter rear seat, smaller washer bottle, smaller fuel tank, all the small savings add up. The wrx is lighter mainly due to lack of six speed box, smaller brakes and diff no high rear wing, narrower wheels and probably a few more bits.

I think ive just gone off spec C's. It's nice to have a light car but at what cost. I'd rather have front crash protection, side impact bars ect and lose a few horsepower per ton.

The body is strengthended, its the only new age to be properly seam welded, and I doubt you would notice much in crash tests, all the classics had neither the front crash protection or side impact bars, and their shells were not as stiff as a new age.

I wonder how they would score in the Ncap tests today and what they would be comparable too?
I can understand a light weight shell without the safety features like a spec C if it were a competition car and likely to have a cage welded in. But one of the reasons i chose my scoob was because of its safety in a crash. I sold it to the misses as a performance car that was also a safe family saloon car

Those are not side impact bars, someone put those in there to stop the doors blowing off in the wind

Yep always makes me laugh when i see someone on about making their car lighter and and spending a fortune an a titainum exhaust, carbon boot, bonnet and door cards ect,ect and they are a lard ar$e,

They could save a fortune in food bills and carbon parts if they just ate less and slimmed down, then take a dump before they go down the drag strip.

I work on the theory that even a spec c with some safety items removed to save weight would still be a lot safer than most cars from a few years ago, my cossie is 1200kg approx but has no safety gear at all, but am I worried, not really. In a big off you need more than door bars and a front subframe to save you from injury.
