Most of the performance equipment sold by Turner Motorsports, BMP, etc, was originally designed or developed by Korman way back when. You can perhaps save a few bucks by buying their reproductions, but they are really just parts retailers. Just try and have your head reworked, or ask one of their staff a question about transmission mods, or suspension tuning beyond the bolt ons. You will quickly find out that price alone is not everything. Will Turner is a great guy, and his racing team is respectable (I'm actually a fan) But his business has a ways to go before it can match the full scope of knowledge, service, and products of Korman Autoworks.
