I personally wouldn't buy from strc OR gpm. I've seen mixed reviews for both. STRC is making more than just traxxas parts. They make some HPI parts, too(at least for the wheely king). One guy on RC Crawler bought a set of aluminum links for his WK from STRC. Within a couple of runs all four of the lower links were broken. It turns out that the threaded portion of the links were only about 2mm thick.[:'(]
