Complete set of titanium rod bolts and nuts designed to fit the factory rods for 2.7 and 3.0 motors. Each rod bolt weighs 16.6 grams less than a factory rod and each bolt weighs 2.5 grams less. These save a total of 38.2 grams per rod. Porsche used to make titanium rod bolts for these motors but discontinued when they were retired from racing. These work great for helping the bearings last on higher rpm motors.
