550/575 H GTC and Fiorano handling packages

I am trying to determine the difference between the suspension components on the Fiorano and GTC suspension packages on the 575.
From my research so far I have come to the conclusion that the Fiorano handling package on 550 and 575 seems to use the exact same part numbers, so there is no difference between the two.
What I can't determine is whether the H GTC package is the Fiorano handling package with the upgraded carbon brakes or an as two magazines I have read have conflicting information in this regard.
I have spoken to my local dealer, but they have no details of the GTC option as yet, let alone spare parts info.
Is anyone here able to shed any light on the subject?

 

Thanks guys, I was actually looking for more tech info on the suspension.
Here is what I know so far;
On the GTC the springs are 35% stiffer front, 15% stiffer rear, rear sway bar 75% stiffer.
Fiorano springs are 25% stiffer alround, rear sway bar increased to 21mm.
The Fiorano spring specs are not confirmed and come from this article:
http://www.theautochannel.com/publications/magazines/forza/number9/pg38.frame
The Oct issue of Forza quotes the GTC Handling pack as being the Fiorano kit with the addition of carbon ceramic brakes, wheels, exhaust etc, which is inconsistent with the specs they quote, being the same as in EVO, listed above for the GTC.

The reason for my research is that I was ordering a Fiorano upgrade for my car, but am now thinking I should perhaps look at the GTC suspesnion option instead. Unfortunately I seem to have an inability to delay gratification, meaning that I want it yesterday, which is why I am trying to get to the bottom of whether they are actually the same thing!

 

No, I only put an enquiry in on the GTC kit yesterday, but as they don't even have details on the car option yet, it may take a while for the upgrade pricing to be released

 

For anyone that is interested, I did some calculations on sway bar effective rates and calculated the Fiorano bar to be around 75% stiffer than stock, the same as the GTC bar.... I get the feeling that the Fiorano and GTX suspension kits are likely to be the same mechanically, although the electronics may be different.
