So I've bought an secondhand cooper s rear to put on my Dooper.

What more do I need to order from the dealer?

Dual foglights - Yes (do they come with the needed cable to make both fog lights work instead of just one? )

anything else?

exhaust system lol? d exhaust is on the right cooper s is central?

go to total mini someone ha changed their rear dooper bumper for a cooper s one and centralised the exhaust as well.
