bigger rear disc in rear than front a problem I assume?

So, the reason why I said they shouldn’t fit is because Wilwood says they shouldn’t. This is the instruction sheet for that kit

The diagram indicates the base radius of the hub snout is 3.24”, and the instructions say the minimum hub bore for the wheel should be 3.24”.

The minimum hub bore on a set of Mopar cop wheels is usually somewhere between ~2.8” and 2.9”. Less than 3” certainly, at least all the ones I’ve seen.

So, my concern would be that the hub bore of the wheel is sitting somewhere on that radius, and that would mean the wheel wouldn’t be sitting flush against the face of the hub, and that the lugs are distorting the wheel to clamp it all together.

I haven’t mounted them up, so I can’t say for sure. But that combo doesn’t fit according to Wilwoods instructions.
I have the wheels on my car, I have on issues going down the road with these wheels. Was just trying to help.
