Its long story about 2nd set, nothing wrong with this 2nd set and they are brand new in the box with Tanabe certificate and stickers too.
Your 15" and my 16" will be pretty much same diameters with tires, you won`t have any problems for sure.
roughly what are we talking here $$$$ wise...?
2015 Micra S (manual)
no A/C /no power options
Feb 2015 build
9,999 purchase price + tax..no additional 1600$ because it was a 2015 purchased in 2016
so receipt says $8,399....+1600 .... so they look good i guess...for a brand new car!
