XJ6 Dimple Wheels

I’m looking for a set of Dimple wheels for my newly acquired XJ6…

I noticed that there’s a 7J and 8J version for the Dimple wheels. What’s the difference between them apart from being wider and the 8J is slightly more ‘concaved’?

Should I buy the 7J or 8J if I’m hoping to achieve a more classy and elegant look?

Any suggestions are welcomed. Thanks!
