Anyone have problems using AL wheel adapters on steel drum or rotors? how can you stop galvanism?

 

I use them on my GTR, used them on a few other cars before. Never had any issues. I'd just slap them on and have a go

It's the same as an aluminum wheel on a steel hub/brake. Some OEMs reccomend a sparse coat of anti-seize on the mating surface after both side have been cleaned. Painting one or both parts would help as well.

 

The proper term is galvanic corrosion. It occurs in moist environments where 2 dissimilar metals are in direct contact, or the gap is small enough to be filled with a film of water.
Wheels are not a big deal, as it should only really occur around the outside edge if it's sitting, and if you drive it, the heat of the brakes should dissipate moisture in reasonable time.
As mentioned, anti-seize works great if you are truly concerned about it.

 

its caused pitting on my spacers after a few years. i just hit it on a belt sander.

 

I'd be worried to put any coat of something between a wheel and the hub or between wheel, hub, spacer or adapter.

After all its the friction that holds the wheel on the hub, if you have no friction between them, the whole load will be on you wheel studs or bolts. Thats my Way of seeing it, but I might be wrong!

Isn't there some kind of gasket that is made specifically for this? I'm almost positive that I've seen them before.
