    LOL...! I don't mind serial numbers being sent to my phone - as long as some kind of information is included. I have the Simply Unlimited plan, so a barrage of texts would be more than welcome (hint, hint). :D

    Oh, so Dave's post wasn't an suggestive attempt to unlock another obsession within you, i.e., determining where and in what condition every i-phone in the country is located?

    No. The only iPhone I care about is the one I hope to one day have with my current Sprint plan. He sent me a 575M serial number, thus his strategically-placed albeit assembly number-remiss post in this thread.

    Jake, do you have the original books with the car...? Did a Becker code card come with the books...? It looks like this:

    Yes, I do have the card and it also says Becker on the CD changer itself.

    Rob- Most likely they fitted the Becker changer earlier and then made a production line change to make assembly simpler later in production.

    If you ever wondered how your exhaust bypass valves work, here is a factory bulletin explaining how they work plus the applicable parts catalog page showing where everything fits. There is a long vacuum hose (6), which carries the vacuum from the vacuum accumulator (1) to the inlet of the exhaust bypass solenoid (27). This solenoid is a simple on-off valve which opens when the Motronic ECU sends a signal to it based on rpm and throttle setting. Opening the solenoid valve allows vacuum to pass through the "T" fitting (25) and out to the pneumatic control valves on the inner exhaust pipes, opening them.

    The bypass valves themselves are closed by spring pressure and opened by vacuum on the pneumatic actuators. With the engine off, the valves are closed. Once the engine is started and warm, the valves are open at idle, close at 1000 rpm, and reopen at 2720 rpm and 64% power (throttle). Lower throttle settings will keep the valves closed until higher rpm based on a 2D rpm and throttle map contained in the Motronic ECU.

    If you want to try reversibly bypassing the solenoid and having the valves open whenever the engine is running, this is very easy to do. Disconnect the solenoid valve outlet hose from the "T" fitting and plug the outlet hose to prevent solenoid contamination. Next disconnect the long vacuum hose from the solenoid inlet and attach it to the top of the "T" fitting. Again, plug the inlet to prevent solenoid valve contamination. (Alternatively, take a piece of vacuum hose and connect the solenoid inlets and outlets in a loop, saving the original solenoid outlet hose). This will provide vacuum whenever the engine is running and definitely make for a louder exhaust. If too loud, easily reversible.

    For you electronic geniuses out there, it is also possible to set up a remote solenoid override switch, which will allow you to choose when to override an ECU closed solenoid signal. Corvettes have been doing it for years and use one of the interior Homelink garage door buttons. Here is an example of a Kreis-Sieg system on a 599 with remote control of the valves.
    http://www.ferrarichat.com/forum/showthread.php?t=249868

    The 550 system is similar except the bypass valves are closed at idle and open at wide open throttle and an unknown rpm. The 550 WSM says to check at 5000 rpm and WOT to ensure the pneumatic valves are open.

    Piling everything into this thread to give a source for most 575M data.

    550 and 575M wheel sizes, offsets, tire sizes and diameters. Plus how to calculate tire diameter.

    550/575M 18": F 8.5J X 18, offset 43.65 mm, 255/40 18 tires; R 10.5J X 18, offset 32 mm, 295/35 18 tires

    Rear Tire Diameter: (295 X 0.35 X 2) ÷ 25.4 = 8.13" + 18" = 26.13"

    575M/SA 19": F 8.5J X 19, offset 43.65 mm, 255/35 19 tires; R 10.5 X 19, offset 32 mm, 305/30 19 tires

    Rear Tire Diameter: (305 X 0.30 X 2) ÷ 25.4 = 7.20" + 19" = 26.20"

    Henry- Affirmative. You should be able to look on the back of your Barchetta modulars and read the size and offset.

    Carbon- One of our regulars has an early 2004 and I am trying to beat him out of the numbers with no success so far.

    By request of some 575 owners who thought they had to change their cam belts at 3 year intervals, here is the bulletin confirming the interval was extended from 3 years to 5 years on 575s and 612s. There may be some very early 575Ms with the old belts, but all US/Canadian cars came with the 5 year belts.

    Alarm remote fobs next.

    Terry, my obsession isn't limited to contemporary front-engined masterpieces. Serial numbers (11649(?), 14009, 135171) of all Ferraris are equally important. :)

    As promised, here is the low-down on the alarm system and remote fobs fitted to the 575M and 575 SA. Applies to the 550 and earlier V8s as well.

    Carbon- The 575M used for the Owner's Manual was ZFFBT55B000125381 and engine number was 65877. No assembly number shown. Probably a pre-production model since the SN is only 10 higher than the Geneva show car.

    Here is most of the data I have found on 575M pricing and options, including Danish export prices, UK, and US pricing. If you have any trouble reading the numbers, right click on the jpeg image and "save picture as" to a file. You can then blow up the image and read the numbers.

    Henry asked about height settings for non-FHP 575Ms. Here they are for stock and FHP/HGTC according to the WSM. See the FHP bulletin for how to measure. All heights plus or minus 5 mm with full tank of fuel and 75 Kg (165.3 lbs) in each seat. Rest of the alignment specs, too, under the same conditions. Caster is fixed at 5 deg 30'.

    Standard 575M: Height: F 196.5 mm, R 201.3 mm Camber: F 1 deg + or - 10'. R 1 deg 30' + or - 10'
    Toe-in: F 3 mm + or - 0.5 mm, R 3.5 mm + or - 0.5 mm

    FHP 575M: Height: F 186.7 mm, R 194.2 mm Camber: Same
    Toe-in: F 3 mm + or - 1 mm, R 4 mm + or - 1 mm

    Henry- The flan blocks (mistakenly call flamblocks in the parts catalogs) are the bearings/bushings for the A or H arm suspension. Four per suspension arm, the one you want to use is #2 on this rear suspension drawing from Ricambi's site. The measurement is made from the center of the bolt passing through the flan block (flanblock), #20.

    terry -

    if you have a set distance from the ground to the FB (essentially a point on the lower A arm), can't u still have different ride heights ?

    the springs, perches sit above the A arms and arent they adjustable ? wouldn't u also need another height reference point (say to the fender arch or something) ?

    Henry- They are adjustable and that is how you set the ride height. The body is firmly attached to the frame so moving one moves the other. The lower A/H arm mounts are heavily welded to the frame to ensure no movement except rotation around the flan blocks.

    There is another set of adjustments for shock absorber height based on the color on the ring nut on top of the shock/spring assembly. When fitted to the car, the strength of the spring was measured and the springs were matched as pairs and assigned a color based on that strength. The shock absorber ring nut was then painted that color. The ring nut is adjusted to give a correct shock absorber height from the upper shock absorber washer to the lower fulcrum point (mount center). Ring nuts can be unpainted (FHP/HGTC only), yellow, white, or red. The difference is only about 4 mm throughout, but important enough to spell out in the WSM and FHP tech bulletin.

    Note ride height is measured from the aft lower flanblock bolt's centerline, not the front, since flanblock heights vary for anti-dive and anti-squat geometry.

    i found a old note in my files...

    from assembly number 50297 the brake pedal changed position.
    it was mounted more on the left (not to the accelerato pedal),
    so that the space between arrives to 55 mm(before was 35mm).
