I need some spigot rings to fit some Peugeot alloys to my 924. (The wheels already have a chamfer on the lip for a spigot ring to sit in) There are Plastic ones on eBay for £9 - linkand Stainless Steel ones for £11.50 - linkAnd I believe you can get Alloy ones too but I haven't found them in this size. My instinct was the Stainless ones would be best but my brother thought plastic so now I'm not sure. My thinking was stainless ones would handle the heat better and be tougher. My brother mentioned the stainless in contact with the alloy might react? I did Google to try and find out but didn't find anything useful. Has anyone here used stainless ones? -Steve- |

plastic. your brother is right about galvanic corrosion between stainless and aluminium. plastic removes the potential problem from the equation. they never support the weight of the car is used correctly, so it doesnt matter how 'tough' they are.

I have used Plastic ones before with no issues with wear etc. The point about Galvanic corrosion is a good one even with Stainless being very resistant
You could argue that the unsprung weight could be less with the plastic ones but that honestly is clutching at straws!

the stainless will be largely fine, as it acts as the cathode. it will be the aluminium that suffers badly as the sacrificial component.

Hi, the electrolytic action is caused by two dissimilar metals, so Ali to steel will suffer from it as well. But a simple coat of paint will lessen the effect.

The wheels have a powder coat on the surface the spigot fits, and the current plastic (ford) spigots seat in them OK. But I might need to scrape the coating off to fit the new rings if the tolerances are as tight as the .1mm implied. I think I'll just go with plastic as suggested. I'm having a hard time finding suitable wheel bolts too. The nearest I have found is these link but they might be a tad short. Its a lot trickier than I expected to get these fitted properly! -Steve- *Plastic ones ordered* |
