Has anyone tried or know of someone that has tried these wheels. Does back spacing and offset seem like they will fit the S197.

Looks like they custom weld the centers for each order. Should just be a matter of telling them it's for an S197 and they should be able to provide the proper offset and backspacing you'd require.

To be honest, I only recently learned what both of those terms mean. I'd recommend reading these two things before you go too much further.
