So one of my wheels started to show some corrosion/defects near the lug nut holes on the face (see close up picture) of one wheel and another wheel lost its center cap.
The center cap gone missing was probably due to when my driver's brake caliper locked up and heated up the wheel, causing the plastic tabs to lose their grip and finally sent it flying off one day.
I contacted Tony (Norcal SS) with a picture of the corrosion and he had Factory Reproductions send me out a new wheel within one week. The new wheel was mounted yesterday and I had the shop take the center cap off the corroded wheel and put it on the missing wheel. The damaged wheel is already on its way back to California.
Hopefully that wheel is just a one off issue. Back to status quo for today.
