Help me pick a Stud conversion

[Wild Ride]

I'm looking to convert my lug bolts with studs. I am currently running black rota slipstreams and am looking for reccomendations for quality studs and aluminum lug bolts anodized black nothing too long. Any reccomendations of brand and length of studs would be much appreciated. What length should I be running without spacers? I assume the required length of the studs will increase by the thickness of the spacer if I choose to run them in the future.

These are my wheels


I had something like this in mind:

I run the vorshlag studs and 949 racing lugs.
