    I am a future buyer of a 575 and wanted to map out the process to upgrade a non FHP equipped, earlier MY 575 to mimic the performance upgrades those later cars got. I and many others in the market most likely will end up with one of those. So far, the upgrade list based off all my research looks like this:

    1: Upgrade steering ECU with Maranello Skunkworks p/n 175891 ~550$

    2: Upgrade shock ECU with Ferrari p/n 201673 (if available) or 205619 (I’ve heard these can be bought new) ~2000$. I’m not sure what people consider the “best” option here however. There seem to be quite a few options to choose from I haven’t listed here.

    3: MSW anti roll bar 210888M - seems to be NLA but the right one to get. Does anyone know where to source one? How expensive are they?

    4: Springs -??? This seems to be a bit of a mystery. There are random aftermarket springs I’ve come across but no option that people consider a go to or have any solid reviews. Original FHP springs are a non starter as well. Some people go Muller coilovers but this gets rid of the variable damping functionality which I like and nullifies the shock ecu upgrade.

    5: Brakes - Also somewhat up the air. I see no reason to change the stock pads unless they’re extremely dusty or noisy. Not looking for track pads.

    Anything else I’m missing here? Would love any feedback from people who’ve done this within the last few years. Parts availability seems to be the big obstacle.

    Ask Daniel when John will supply him more rear anti-roll bars.

    205619 is better than 201673 and available. 201674 is also an upgrade to 201673, but largely unavailable.

    Springs show up here occasionally. HGTC springs are very slightly stiffer than FHP and work fine. Mixing FHP and HGTC springs F&R would work fine. So close, no noticeable difference in handling.

    I have a set of take-off FHP pads, but they will squeal for quite a while until bedded. After 15,000 miles, mine only rarely squealed. The entire set of brakes was replaced with ceramics.

    I have FHP on my '02 but now dealing with 1or 2 bad shocks, hopefully solved by using a salvage set. In doing research on shocks, etc., if I was in your situation, I would seriously look at an aftermarket solution. One possibility are the MSC coil overs. Probably least frustrating , cheapest way to get on the road with improved handling. No personal experience.

    I just replaced my suspension ECU 201673 with 205618 for about $3600. Andy at All Ferrari Parts was delightful to work with and WAAAAAY less expensive than the dealers. How "future" of a buyer are you? My 2004 575M is getting the dashboard recovered in two weeks and then it will likely be on the market. I just haven't put enough miles on it to justify keeping it.

    Because demand has trailed off for these swaybars since the initial production, we're likely to order the next batch on a 'pre-sale' basis only. That is, we'd have a window of opportunity for customers to purchase the bars before we enter production. But, we'd only produce the requested number of bars plus a very few extra.

    I do not have a timeline or revised pricing at the moment. My best guess would be Q4 delivery to customers.

    Well as of yesterday I just put a deposit on a 2003 575M so the future is now!

    Mr Ricambi consider me a guaranteed buyer when new bars come up for sale.

    When you take delivery double check steering & suspension ECU p/n - many have already been changed

    The cheap(er) solution for springs is to get a set of H&R springs (I think PN 29288, spec'ed for the 456). I don't have documentation for the stiffness but supposedly they are slightly stiffer than the HGTC spec, but progressive so softer vs small bumps.

    Alternatively can hunt for a set of HGTC or FHP spring set (expect to pay $$$). The rear FHP springs are NLA but nearly identical to HGTC (ie specs nearly overlap so if both red label, the HGTC springs are ever so slightly stiffer in the rear but a red FHP rear spring is stiffer on average than a white HGTC rear spring).

    This got me curious. Possibly a dumb question, but what are these rear springs listed on the Eurospares website?

    "Cagnola - PN 175887- Valid for cars with handling - Optional Fiorano equipment"

    "Cosmos - PN 208679 - As an alternative - Valid for cars with handling Fiorano equipment - Optional"

    FHP and HGTC springs, respectively. Again as mentioned the rear FHP springs (175887) are NLA (unless something changed/they made another batch but last I spoke 2ish years ago there was no plan to do so) but nearly identical to HGTC. The main difference in that HGTC are slightly longer and faintly stiffer when apples-apples comparison. I run HGTC rears (208679) as sub for FHP springs on my 456M. The slightly longer travel and stiffness is welcome for the heavier 456MGTA.

    That's what made me curious. 175887 is available to order new for £697/pair on Eurospares.

    Very nice color combo. Do you know the cars history? 5k miles in 22 years is a little odd. Did a reliable shop do the belt service? I'm not sure what to look for in very low milage 575 but I'm sure there are people here who can give advice. Only thing that comes to mind is check for gas smell in trunk and cabin.

    Definitely that. Also, anything that can dry out or seize or be ravaged by ethanol

    I know it’s a Euro car that was federalized (thus updated to US spec with mph gauges etc). I test drove it and it felt like a rocket ship, AC worked perfectly and the sticky buttons were all treated. Never noticed any gas smell, but I’m assuming you’re referencing the fuel pumps rubber perishing? Is this problem common across 550 and 575? Regardless I’m not scared to deal with whatever comes my way. Belts and fluids replaced in 2024.

    IMO, the 575 is the last "old school" modern Ferrari. I've owned mine for 20 years and 115,000 of mostly trouble free driving. Just keep up with the maintenance, which isn't inexpensive but worth it.

    Looks like you are missing the RED key fob and make sure you get the PIN to start the car. If that stuff is not available then you might want to contact gobble on fchat to find out what it takes to make your car complete from that end. You really want a red fob and the PIN. You can get the PIN from Ferrari for big bucks and they fail to produce it at least 50% of the time and an EURO car in the USA makes ferrari want to help you less. Your dealer might promise it but they will 100% never come through. I think gobble can recover the PIN and I'm pretty sure he can get you all the proper FOB's.

    That’s amazing miles! Coming from the BMW M world I’m well aware of maintenance stuff. Just finished a complete top end/VANOS rebuild on my 180k Z4M Coupe. Mechanical maintenance is therapeutic for me so an older school Ferrari with modern performance is the ultimate dream car. Would love to hear your thoughts on weak points to think about addressing preventatively.

    Going to need to investigate this fob and PIN business, was not aware of this issue. What’s the worst case scenario if I don’t have these items?

    It's like having missing tools. The value of the car is lower. Find out the cost of replacing these things and the very real possibility you get no where with Ferrari and you will know why that's important. The RED is a master and has some special features the blacks do not. You can clone extra blacks but there is an issue I can't remember like how the black transmits and after a while of suing blk1 if you suddently use cloned blk2 you have to press button a bunch of times to get the codes to synch. I forget exact details gobble can tell you. The the PIN is the way to start the car if your battery dies in the FOB of if the FOB does not work for some reason. I have needed to start my car with the PIN in the past. It is valuable to have. A potential owner will want all these things. Some buyers will pass on incomplete cars because there are so many cars to choose from. I am being picky. You can enjoy the car just fine with 2 blk fob's. It's just if I was buying a maranello and wasn't fully educated I'd hope someone would clue me in. I forget what ferrari was charging to get a PIN but I think it was in the $1000 neighborhood and you might not even get it. Gobble services could in in a similar cost neighborhood I do not know but he is a stand up guy and provided these services for many owners. I do not know what his current status is but I think he is still active in this area.
