I used to work at Summit in Sparks, NV and always had good luck with the Summit brand. Back then (3 yrs ago), at least, I know that Summit manufactured nothing in-house. All of the Summit brand parts were just rebranded stuff from one of their vendors.
Man, I sure miss the employee discount!! Got a set of Trick Flow heads (Summit owns Trick Flow) back then for a small block Chevy for like half price!
