Hi can anyone tell me if these alloys will fit a stock not lowered R53 Mini Cooper?

I know the offset is way off from the stock et48/et43 but I'm finding it tough to find decent 4x100 alloys with tyres in 15inch size.

At a guess I think it just might be okay with a reduction in tyre width to 195 along with the fact they are 15inch. Will probably need to adjust the camber and drop the car to make them look right but comfort is my main aim at the minute.
