AC Racing Subframes duplicate the stock subframes except out of aluminum. We use square or round tubing depending on the OEM manufacturer. All tubing is CNC bent for quality and accuracy. All lugs and mounting points are made of 6061 billet and CNC machined.We use stainless steel inserts where threads are to eliminate rusting and threads from wearing out from repeated service. All subframes are heat treated for maximum strength. These subframes are also lighter than the steel stock subframe.
