please can someone tell me if there will fit onto my mini cooper they are multi stud fitment alloys, and also would i need to purchase anything extra to fit them

Can't answer your question without knowing the bolt pattern, centerbore and offset.

if they came off a vauxhall then yes, as they are 4 stud pcd100, u need to find out the offset, you would want something around et45 mark, give or take each way a little, lol
