    Robie- The FHP springs and HGTC springs are identical, as are the rear anti-roll bars. We think the FHP steering ECU was made standard on all 575Ms sometime in the late 2004-2005 MY, because it is not listed in the HGTC package. In late 2004/2005 MY the rear shock absorbers (from assembly number 55769) for the HGTC package were made standard on all 575Ms, possibly the fronts. Too hard to tell on the fronts because there are two different numbers, one for the HGTC package and one in the parts catalog.

    Also at 55769, a new shock absorber ECU was introduced, but it is different from the HGTC shock ECU, misnamed as an FHP shock ECU in Ricambi's parts catalog. Some of the HGTC shock ECUs were fitted before the new shock absorbers were introduced as standard. But those shocks may have been fitted only to HGTCs until assembly number 55769. Do not know. Only way to know would be to check the part numbers on a very early HGTC car, and that is unlikely to happen. I think the shocks were late 2004 shocks on very early HGTCs, but am not sure.

    The HGTC F1 shifter ECU was unique, as far as I know. It only speeded up shifting, no other features. FHP never included any shock absorber related or F1 shifter related components, as far as I know. F&R springs, R anti-roll bar, steering ECU, and calipers with Pagid 4-4 Orange pads. The 19" wheels were a separate option and available on any 575M, but standard on HGTC 575Ms (18" wheels do not clear the CCM brakes) and on all 575 SAs.

    Do not know how different the HGTC shocks are from the 2002-2004 shocks. If I were spending money, I would buy the HGTC shock ECU (~$1000) and forget the ~$2500 each HGTC shock absorbers. If you have a 2005 car, you likely already have the HGTC shocks anyway. The shocks on our 575Ms will likely never wear out because Ferrari got rid of the troublesome 456/550 Bilsteins and introduced bullet-proof Mannesmann-Sachs shocks.

    Thanks, good to know re: the shocks. I'm getting the FHP springs, sway bar, steering ECU installed but will probably hold off on the (much contemplated shock ECU) for the time being. Might be a good gift idea, though!

    Any stats on how much faster the GTC shifts are vs. stock? I drove an SA GTC a couple years back and the shifts didn't seem faster (though the brakes were much different), though that was right after I tried out a 599, which may have skewed my perception of the speed.

    Robie- The 575M upshifts in Sport take 250 ms (1/4 second), on the HGTC it is 180 ms .

    Carbon- Believe we have a typo here. Could you double-check these numbers?

    122976 - 46985


    122976 is earlier than all the Barchettas. 129x76?

    122976 should be, although unconfirmed, a Modena, it fits well in a chain of cars of this type. Earliest Barchetta is # 108995, said to be a PF Prototype. There are 12 Prototypes in total in addition to the 448 production units: 121389 121680 121933 122529 122544 122760 123074 123652 123654 123655 and 123657. First production car is 123075, second is 123674 and the last is 124426 (all in order of its S/N, the ass. # shows the "real" order of production). Ass. # of those early cars are meandering roughly between 40550 and 41100.

    Ass. # 46985 should be beyond S/N 128700.

    Mathias- A friend of mine has a much later US HGTC 575M, SN 141817 and assembly number 59570. Very nice car with custom gray paint, CF, Cuoio Daytonas, leather shelf, etc. A really desirable car and must be very close to end of production. Updated list attached.

    Thank you for this, Terry,

    I know, the Book is "incomplete" and ever will be, but, I guess, that's quite normal as long as the Factory does not publish any full Serial Number list, what they, in my opinion, never will do. The Book in its printed version covers approx. 120.000 cars of 150.000 produced, the error ratio of the data should be around 0,1 %. The update, planned to be published as a fully revised version of the Book with many additions shows the quota of covered cars has risen to approx. 130.000 cars at least and is due to arrive in late 2010.

    Thank you, Don. I don't believe that the engine number can be seen on the engine while the engine is still in the car. So if you want to pull it out and check, I don't think any of us mind waiting. :D The easier way, of course, to find out your car's engine number, is on the first page of either of the warranty cards that came with your car.

    Matthias, you say there are 12 Barchetta prototypes, but only list 11; do you know the 12th, or is it still unknown? Also, I have 108995 as a 550 Maranello, not a Barchetta. Do you know for sure that it's a Barchetta...?

    I have assembly numbers 22488 and 22513 with 105039 and 105096 respectively.

    I have 142227 as my highest 575M (through Carfax), but it's also a discrepancy with a European F430 F1 Berlinetta that was for sale at Kroymans back in December. Do you, perhaps, have a picture of the VIN?


    I saw this car at the 2006 Ferrari French Quarter Classic in New Orleans, LA, date of production, November, 2004; leather interior, black leather steering wheel with tan leather on the bottom, modular wheels, carbon ceramic brakes, Texas plates.

    For you serial number collectors, Ferrari did a service compaign to update all the F1 ECU software on early 575Ms. Included in the tech bulletin was what looks like a pretty complete list of early US serial numbers. Here it is. I can do a Word version, too, if it makes it easier for someone.

    Thank you, Terry. Oooh, RHD! Sweet!

    Now this is awesome...! Thank you, Terry...! I've found some discrepancies with information I already have - perhaps you and/or Matthias or others can help. I put the serial numbers into a Word document as well as an Excel document (attached).

    One s/n that was not on the list helped me determine that it was actually a Euro car, not a US car. But I have a US car, 127585, that's not on the list but has been identified as an F1. Is there any reason why an F1 that falls between two cars on the list wouldn't be on the list...?

    I have pictures of 128467 and it's a manual - but 128467 is on the list.

    I have 128474 as a European 575 with a manual transmission. Can anyone confirm that it is or it isn't...?

    I have 128658 as a manual through a few different sources.

    I have 129315 as a manual - and so does Sheehan - and pictures on duPontRegistry.com prove it's a manual (a Google search of the VIN has it as a manual in a bunch of different places).

    I have 129440 as a manual - can anyone prove/disprove...?

    Looking through the 575M/SA technical bulletins, I came up with three new sets of numbers, but know nothing else about the cars:

    Service Campaign 153 involved checking and possibly replacing the electric fans if they had insufficient clearance and could hit the fan shroud. Affected cars were between SN 137514, Assembly # 55063, and SN 138899, Assembly # 56292.

    On the 575 SA, screw fasteners were changed on one of the roof hold-downs from SN 145120, Assembly # 62504, and needed to be replaced on earlier Superamericas.

    If anybody has additional info on these three cars. Please post it. Easy to see where these three are in the list.

    This car, TdF over dark blue, was for sale at Autosport Designs last year in February; Daytona seats with red inserts, dark blue dash an steering wheel, shields - advertised as having a Fiorano package - 1,000 miles from new, $176,500.

    I saw this car at the 2004 French Quarter Classic, titanium with charcoal leather, Daytona seats with gray inserts, shields, modular wheels, black calipers. Since then, it has been for sale in various parts of the country including Louisiana, Missouri, Arizona, California and Nevada.

    Grigio Silverstone with black interior, GTC; but I don't know the transmission type.

    All three of these assembly numbers were new for me, thank you, Terry.

    Carbon- The latest update with the additional information added. I found out some more interesting things about the MY 2004 575Ms, but I think I will do a separate thread and perhaps also paste it in here to keep everything in one place.

    Terry, do you know what issues this software update addressed? Also, any idea whether the campaign extended to Europe/Asia as well?

    Robie- I just glanced at it at first, but it actually changes both left and right Motronic ECUs to work better with the Lambda sensors. I believe it should have been done to all early 575Ms, but I only have the Ferrari North America technical bulletins. A visual or SD2 test can tell you whether you have the latest version software 001. Here is the entire technical bulletin.
