The first time I bought steel, I didn't know what I was doing and I got brushed. My polisher hated me for it because he had to sand it first. So I did only one set from my brushed stock. The sheet just sat in a corner and got old. But recently a TT.net member asked for a custom brushed SS WingZ and it turned out nicely, so I decided to make a "spec" set. It is specifically made for the Howe/AMS(PWR), but it will work with the Koyo. The core support holes have not been drilled, so the buyer can choose TT, or NA if his Z32 is converted. Mounting hardware and instructions supplied.
