I have the head bolt kit, and con-rod bolts from Raceware installed in my Coupe engine. Their quality is superb, as well as outstanding craftsmanship! The head bolts are reusable, and VW Motorsport endorses them! They are vastly superior to the OEM's in every respect! Someone looking to "modify" that turbo engine for higher boost, may consider the headbolt kit! Its cheap insurance! M
