I'm ready to address the leaking rear shocks on my 458. What's the latest? Did you go with Nagengast? Has anyone used Maderno?
I used Nagengast and communication with Raf was good. I placed the order on a Sunday and he was emailing me.
Finally got my shocks back from the rebuild and happy to share the details My friend from Moscow has recommended a shop in Novosibirsk called "Workshop #1". He had a shock from his R8 (also Magneride) rebuilt by these guys some time ago. Their website is https://2148226.ru/. They specialise on rebuilding Magneride shocks for GM SUVs (Escalade, Suburban etc), but happy to work on other marques too. Price was $350 per shock + shipment which is about half price of the Polish shop mentioned further up in the thread. Shipment from Dubai took 7-8 days, their turnaround time was 2 days, shipment back to Dubai another week or so. The guys are great in comms, constantly updating on the progress, steps they're taking during the rebuild and recommendations post install. They give 1 year unlimited mileage warranty which may not be such a big deal for Ferraris since we're not doing crazy miles, but for SUVs it would be an important consideration. Post install shocks operate as intended with the button on the steering wheel and manettino in wet-sport-race. Car feels firmer and tighter on the road. I understand this option may not be of much interest to the US or Western Europe members, but for those closer to Russia this shop is definitely worth a try.
Hi F-Serge, Thanks for sharing your experience. I have a similar issue with my shocks as they’re leaking. I’ve already reached out to the Workshop #1 in Novosibirsk via their WhatsApp contact. They quoted me $500 per shock, citing increased prices due to taxation and other factors. Could you please share more details about your experience? 1. How much was the shipping cost (both to and from the shop)? 2. How are the shocks performing now after some time? Are they still holding up well? 3. Did you notice any issues or changes in performance after the rebuild over an extended period? Your feedback would be incredibly helpful as I decide whether to go with this rebuild option. Thanks in advance.
hi Fawaz Shipping from Dubai was I think around AED 400 with Emirates Post. Return shipping was around $150 at the exchange rate back then The shocks have been performing absolutely fine, no issues at all and no changes in performance - they're stiff in sport and race modes, and Bumpy road button works as it should
Ferrari dealer charged $3300 to rebuild my California T rear shocks. They sent them off to somewhere in Europe and my car sat in their warehouse jacked up for 6 weeks. It was winter so not a big deal for me.
Has anyone used RMT to rebuild their shocks? I talked to them but he didn't know about the MagneRide system (magneto-rheological (MR) fluid) and said they don't refill them which doesn't make sense. Called back and spoke to another sales person and she said they use transmission fluid in their shocks. Their pricing is 2k cheaper than Nagengast for all 4 shocks. Going to call back Monday and speak to a tech will update then.
They seem a bit flaky. I was going to use them to rebuild some suspension air bags on a CLS550. Originally, they had the rebuild service for them on their site. I called and confirmed they could definitely do the rebuild. A few weeks later, I was ready to ship the air bags to them and they changed their tune and said "we don't rebuild those air bags. We only sell aftermarket replacements" even though the rebuild service was still listed on their site.
Sounds like a place to avoid. Mag dampers by definition have tiny magnetic particles in the oil which when an electric current is passed through, energizes the oil which thickens the oil which in turn makes the dampers stiffer. Putting any other typre of oil in there no longer makes them function as intended. Nagengast have 1st class reviews on R8talk with plenty of satisfied R8 owners having used them. I know where I will be going if/when the time comes.
I went with Nagengast and was pleased with the process. They seem to be the leading resource for rebuilds right now. And sometimes they even have a pair on the shelf ready to ship out.
