They are made from surgical stainless steel on a cnc machine,heat treated to stop future rust and highly polished to a mirror effect.
I was going to put a set on my car but i bought a crap fitting VS bodykit with new indicators mounted above the fin but the fit is so bad ive changed back to the original.
The 2 sets available

an unpolished prototype on my car

If anyone is interested,Make me an offer!!
