WestCoast is the online store of WC Parts Source LLC.

WC Parts Source LLC was formed in 2013. It grew out of what was originally GM Performance, a California partnership that began selling performance cars and parts in the early 2000's.

  • We specialize in parts for Camaro, Firebird, Fiero, and some other select GM models.
  • Our goal is to make hard to find parts available to you. We have changing inventory daily.

By remaining a strictly online company, we are able to add "one only" and low availability type parts without the overhead of store locations, and counter-people. This enables us to quickly bring in new low volume, hard to find type inventory and make it available quickly.

We ship from a warehouse location in Apple Valley California. All orders are shipped via common carrier. It is not possible to pick up parts in person.
Our administrative office is located in Rancho Cucamonga California.
