Porsche Hazet HZ4550 2 119 mm 12 Point Profile Injection Line Wrench HZ4550 2 102 825 What makes these rods different Option:Without Access Holes What makes these rods different from Carrillo's connecting rod is that Pauter sets up these rods to accept a superior rod bearing sourced from a Toyota 1MZFE engine which then allows Pauter to fit a stronger 5 16 rod bolt rather than the 1 4 bolt used by Carrillo for their Porsche 356 and 912 connecting rods No cutting or splicing required simulating tools in virtual environments which then makes a 100% repeatable manufacturing process of the dies HAZET – Safety and precision due to minimal manufacturing tolerances
