I just threw up (no really, I threw up, haha) a Hail Mary and called Delta Vee - it is confirmed the Sachs 575 units cannot be rebuilt. They were intentionally made to avoid that, apparently.
Delta Vee is alive? I thought people hadn't been able to get in touch for years, and were resorting to lawyers to get their parts back?
I’m confused. Madeno racing say they can be rebuilt, as another member also wrote in a thread from 2022, but Delta Vee are saying they can’t? Who is right?
I tried to contact Madeno, not sure it went through; I got an error message in Dutch requesting a number (?). As your are in Denmark could you contact them for information related to 575M shocks. Thanks! I stupidly assumed when I was notified a few days ago that I had a leaking shock, I would pay a Ferrari premium but otherwise not a huge deal.....Wrong!!
The Sachs units were not designed in a way that rebuilding is easy/straight forward. I can't comment on possible longevity of a rebuild either. Current most cost effective solution is either used PAIR (unless you want to introduce a potentially violent lateral instability). Personally I would not rebuild the sachs units unless someone can show proven rebuilds on 575 units. Not the similar but different 360/etc but 575
Right?! I figured it would be high, but this is absurd. Am I to assume all four corners would run you close to $40k?!
That I do. Full pics on my build thread. https://reidperformance.com/collections/ferrari-v12/products/550-575m-coilovers
So Stephen, i just called Madeno Racing. This is what i have for you. He told me that he can do rebuild of the Sachs dampers on the 575 Maranello. It's complicated to understand how they will do it. I didn't completely understand the technical side of it, but what i think he does is this: He cuts off the top part and opens the damper tube, and puts a new top mount on it or something like that. I don't know if it makes any sense? I am in the medical field, so mechanics is far from my strong side. He said something that is made of aluminium, which he rebuilds or something like that. Also he told me that he can do two dampers at a time if the customer prefers, but it will be more expensive. His reason is that it is a labor intense process and will be cheaper to do all four at a time, which he prefers. He told me the price of the rebuild is around 3900-4000 euro plus VAT (Holland VAT is 21%), so around 4800 euro inclusive VAT. He also told me that the alternative is to buy his Öhlin dampers which he offers for the 550 and 575. They will cost 5900 euro plus VAT for a complete set inclusive top mount and bushings. He says it will improve the handling a lot over the Sachs dampers. He asked me if i sent him an e-mail, i told him a friend from the forum had sent it. He told me hasn't gotten to your e-mail yet, but he will answer it.
Wow, very reasonable!! What spring rate did you go with? Wonder if they can produce units that will work with my FHP springs?
Thank you J. A. for taking the time to work on the problem. The Ohlin shocks may be an option. After market may end up the solution if the original Sachs aren't available at a "reasonable" cost.
You’re welcome. Just thought it’s easier for me to call them from over here. I hope you find a solution. What price did you get for new Sachs?
I've got a similar situation with FHP. My car is worthless due to mileage but, best I can tell, it is one of about 15 imported to the US with a combination of Manual and FHP and the only(?) Red one. I guess I have a somewhat misplaced sense of "responsibility" to keep it stock. I've told my wife to keep it another 20 years, it might be worth something.
I guess another question for the decision tree is what are the possible consequences of continuing to drive with a leaking shock? Permanent damage to other components of the suspension? Dangerous alteration in road handling? Sudden, catastrophic, failure of the shock? Other?
Well, my take is there is leaking and there is LEAKING. The latter is a problem, but I’d say you will start noticing some untoward behavior prior to a massive failure.
Well, can’t use FHP/HGTC springs, but so far the most cost effective option. Waiting for numbers on the spring rates available
Taz, they are referring to aftermarket coil overs requiring springs that mount/match the coil overs. As such you can’t reuse the OEM springs. the other way of saying it is that no aftermarket insert substitution exists for the OEM shocks that retains the factory perches/hats/spings
Are there anyone here who has one of these aftermarket shock absorbers on their 575? How is the handling and ride compared to Sachs?
