Hey Chopper,
Thanks for your research and your post...
The one con to SS spinners is weight - I haven't weighed my spinners, but my SS spinners are definitely heavier that my Aluminum ones.
I'm not an expert, but I've heard many talk about "un-sprung weight", and that adding SS spinners only adds to the "un-sprung weight", which I believe is not good - from a racing/handling point of view.
For this reason alone, I use my SS spinners when I have my street tires/Trigos mounted, and I use my Aluminum spinners when I have my slicks/Trigos mounted. I'm lucky to have two set of Trigos
Last, I use a copper based anti-seize compound - maybe this helps with the "dis-similar" metal contact, as I've only had one problem when removing my spinners, and I attribute that to someone else knocking on my spinners one time.
Again, thanks for your research - this is really helpful.
Regards,
Randy R...
