    Would be a bare rod if I weighed them but those were from old notes and could have been gathered from other's posts.

    I am out of town but back in a couple days, I will pull some rods I have out and throw them on a scale

    I have a few sets I can weigh

          i dont put too much emphasis on mass, its way over emphasised for a lowish rpm engine. i didnt choose the lightest rod out there.

          its interesting the pauter 135mm rods are heavier than the 140mm

          BMW Rods: 325E, 325i, 635, 318is, 318ti, M52, 330i, M54, M60, M70, E90, N54, M3, M5, M6, S14, S54, S65, S64B40, S85B50, M20, M30, M42, M44, M50


          its good they come with BE and SE mass though for a 6cyl its less relevant

          as an FYI the ZRP i have are 399g and 165g which also calculates out that the BE is about 70% of the mass like the pauter
