I do not have S197 brakes, but curious as to where is the interference issue with these wheels?

What are your wheels?

Holy cow I posted some pictures

Washers??? Don't let MS see that picture!

it is hitting the spokes....but my install was a little differnt I went with v6 11.2 rotors and the v6 caliper brackets . One theory I have is its got the caliper hitting wrong spot on a 17 inch rim. I had to stack 3 washers on each studd to clear the caliper..33 inch. I am thinking maybe I can try a 12.5 rotor and a 13.2 rotor and appropriate caliper bracket with rotor it will change the spot it buts the caliper at the wheel.

My suggestion would be to mark the wheel where the interference exists, then measure how far out the caliper would need to be placed to gain adequate clearance. 
Or, you could try the caliper brackets for the 12.5” and/or the 13.2” rotors (or rig up something to simulate where the caliper would be) w/o getting the associated rotors, you’d be able to determine whether the caliper will hit the wheel or not.  Remember to make sure the various diameter rotors have the same ‘hub to rotor face’ depth measurement.

Billy, how thick is the stack of washers?

There are 2 different wheel hubs that are very similar.

The offset of the mounting flanges are slightly different.

MS and RPM know about this issue.

Billy, I hate to hear you are having fitment issues. I've thought about changing over to the V-6 calipers and brackets to be able to run a 16" rim for a tire with a taller sidewall for a better ride. It will get pushed out several years since I now have new tires on both ends of the car!!! 

My rims are American Racing VN527 Mag Grey Machine Lip. Summit part number ARE-52778012400. The part number isn't found on the site today. You would have to google the part number for pictures. 

As you can see, the new brake calipers are located past the mating surface for the wheel on the rotor. The factory calipers were not like that. When I was shopping for wheels, I had to make sure there was enough clearance there to make it work. In 2017 when I bought the rims, returns were not allowed once a tire had been mounted. 

Your best shot might be to add a 3/8" wheel spacer. What would that do for clearance to the fender lip? 

MustangSteve has a saying about wheels and cars that I'm surprised he hasn't tossed out here. He did for me.

You mean this one?

IF IT HAS TITS OR TIRES, IT’S GOING TO GIVE YOU TROUBLE

I WOULD RATHER MESS WITH TITS THAN I HAD TIRES.....WHERE IS SALLY YALL USEING KEY WORDS THAT WAKE HIM UP.

I wish I had ordered a 16x7 and a 17x7 when I ordered I already put new tires on the 17x7's I figured them being 17's I would have no problem. I did not realize the made them in 16x7
 

as mysterious as I saw the16x7 in that wheel, now after searching for them It is like they dont make them.

Dealing with issues like this is never fun. Its kind of late now, but finding a drawing like this prior to wheel purchase is a must when we start using different brakes. It's what let me know that what I bought should clear the rotors. Hopefully, the link works. It was the first thing I could find.

Added rambling!! American Racing may have quit making them. Other companies could still make a similar version. I had found the same style by another company years ago that had the back spacing that was more desirable, but it doubled the price. In retrospect, I should have paid the double cost. Coys is someone that sell rims, they would have been my next choice. I talked with someone there that was very confident the wheels would clear any brakes.
