Lower rod angles reduce friction and piston skirt wear by decreasing the piston side loading.  Long rods also can enhance torque in the higher rpm range.  These rods require a piston with a 2mm reduced compression height or a 4mm shorter stroke crankshaft (EJ25 with EJ20 crankshaft de-stroker setup).
