TR/512/M - galvanic corrosion an issue?

Since they are made of steel and aluminum is there a problem with galvanic corrosion on these cars or no? Don't really hear about issues pertaining to this, curious if anyone has any input.

Ferrari developed a special alloy sandwich designed to cut down galvanic corrosion. Forget the name but it should Google up pretty quickly if you try.

Yes, I recall something like that as well. But I can't confirm if it was used on the TR/512/M though...furthest back I can confirm is the 550.

I don't do body work so I can't really say what happens between the skin and the skeleton. I will say that there is an issue with corrosion in the suspension, where the steel bolts interact with the aluminum uprights. The plating on the hardware fails, allowing corrosion to occur between the two metals.

Yes, common on many cars with aluminum suspension parts.

I would assume the corrosion could be removed pretty simply from a raw aluminum part, then I would replace the hardware with upgraded items. Maybe even powdercoat the parts?

Sometimes. Sometimes the corrosion degrades the aluminum too much to salvage. As far as the hardware goes, if it isn't also compromised, you can simply re-plate it in a more durable coating, if originality isn't an issue. Tolerances are usually a concern as well as cating hardness in the areas where corrosion will occur. Powdercoating wouldn't be possible.

So it seems like making sure the hardware doesn't degrade is the key. If you notice any issues with the hardware, take care of it and don't let it be. Then you should be fine...

Didn't even know about this. Will be important when I go looking for a Testarossa myself. Is it only the 512's? or the Testarossas as well?

Any car with steel and aluminum could have the issue.

Since my current car is made out of plastic (mostly) I didn't even think about that. call me silly. I have heard of severe rusting issues in the wheel wells if your not careful, but that is on any car.

But it is nice to know something i can look out for and try to keep an eye out in the future when I purchase my car.

Is this sped up by keeping the battery connected? I usually disconnect mine while inactive.

Makes sense....just like not using the Gold connector kit on the tin ECU.

Would disconnecting the battery during periods of non use really help the situation, or is that an old wives tale?

Would the lack of power to the ECU, etc when disconnected effects things or not?

Seems like most use trickle chargers and leave it connected?

Curious...

Hey guys, galvanic action can occur between any two dissimilar metals which are not insulated from each other even in the absence of any external electrical flow. Disconnecting your car battery will make no difference in the galvanic action between two suspension pieces.
