Back in 2005 I purchased a West Coast Fiero 12" C4 brake rotor kit for my 88. I purchased the full kit with rotors and also the braided stainless steel lines.
I no longer have any need for the hardware from this kit, so it is up for sale for $75 shipped (New sells for $215 +shipping from WCF). The picture shows the brackets/rings for the rear, but all 4 brackets/rings and hardware are included in the $75 shipped price (I just haven't taken the fronts off yet).
The rotors have 40K miles on them and would cost $40 to ship, so you would be better off to buy new ones.
Could ship as early as Monday!
