Interesting, they must have gone to aluminium later on then.

On my hawk its definitely not magnetic

Magnet sticks to mine:Suspiciou

Are all hawk bootlids ali or just he Spec C/JDM `s:wonder:

Tony,

I`m still a bit dubious if my result yesterday was a little on the generous side(As in it was spinning/loosing traction a bit on the rollers?)

I`m happy with the way it drives on the road so not really bothered, Only put it on to get a comparison from the last dyno it had in 2006, Still makes me wonder if it has had anything done to the turbo though?

Gaz.

My EDM STI has a steel bootlood.

My MY06 Spec C bootlid is made from aluminium.

I never knew that.

A few more bits of info here if its anygood to you.

You could have had a bit of slipage on the rollers Gaz, think mine was down because of the winter tyres, ran last time with RE070's, and as the magnet sticks to your boot, its steel ;)

Tony:)

Cheers for the info Shaun. :)

Not until the MY05 Shaun. MY05 onwards they did get a ali boot lid.

Yes. From MY05 onwards. :)

The specs change every year, it's pointless trying to state anything regarding these cars and their differences without stating what year you are refering to.

I made up this comparison, taken straight off the FIA homologation sheets plus the factory spec sheets.

Cheers for the post John! That should answer any question that may be asked in the next few weeks. :D

Prices in Japan using exchange rate at the time
Prices in Japan using current exchange rate in bold
Prices as imported to UK would have been much higher post import duty, taxes and SVA
The Spec C version came mostly as a 17" version, the 16" version was significantly cheaper!

Just looking at the exchange rate differences, you can see why the JDM spec cars are rare and are not being imported anymore, which is keeping their prices relatively high. 2007 was a good year to be a JDM importer! 2012 most definately isnt!

John you got to much time on your hands!! :D

I wish that were true these days! Was in work this morning finishing off a car.

I can never figure out with my Spec C Motorsport is why it comes with factory fitted air con, electric windows and central locking.

Why go for the lightweight version and then add weight back onto it? :cuckoo:

But it's entertaining to drive with no ABS and AP 6 pot calipers on the front. :D

i thought that too,seems odd to save weight and then have heavy items like air con still in it.

I thought that about your car when I bought it over, I think it was missing an oil cooler to for some odd reason. :confused:

16" Spec C doesn't have an engine oil cooler fitted.

Air Con was a factory optional extra on 16" Spec C.

That clears that up then, it was the only 16" spec c I had ever seen at the time.

Juggers, funnily enough I junked the AC when I had the engine rebuilt as the condensor was in the way of my Setrab competition oil cooler radiator.

The only thing left that I'm considering 'sorting out' is converting the DCCD to automatic by the fitment of a controller called DCCD Pro or similar.

how much does the aircon weigh in these things?

Corrected!!

I can second this. I did once have a web page to STI Japan that announced the homolagation of the 05 Speccie.

:lol1:

Great link there! Thanks for posting that up.

So indeed the 2006 Spec C (GDBF4FH) IS FIA homologated.

Tony - how does your UK 340R compare to the Spec C in terms of performance and handling?

I'd say worlds apart in performance terms.
That's based on having driven a spec c in anger, and having owned an MY05 remapped STI with approx 335bhp.
Handling was similar apart from a quicker steering rack.

Dave is a good friend of mine and you Sir,have got a great car,look after it well.

My JDM hawk Sti Type 20 would eat my 340R alive in performance stakes the UK car would need to be 380+ bhp or 400+ to keep up with the response ;)

handling would be similar in standard form. Although I found it to harsh on the road main problem is the very flexible bushes and very stiff suspension doesn't help comfort or handling IMHO

Im not tracking the 340r but if I was I'd would have possibly gone up a spring rate. So I have softened up the suspension with AST coilovers but now need to sort out bushes as too soft

The biggest missings are

No turbo lag
quick rack
Feedback through steering

Tony
