    Transmission weights

    I searched around a bit, but didn't find anything regarding the weight of the 3 z31 transmissions (T-5, 71c, 30a).

    Does anybody know which of the 3 is the lightest and by how much?

    I can weigh the 30a for you when I get home.
    But I am sure the 71c is the lightest, then the 90a, then the 30a.

    That would be awesome, thanks! I was guessing the same thing if weight scaled with how much power it is "supposed" to hold, but I guess it depends on a lot of things.

    I am just theorycrafting if I can shave weight by using scca update/backdate allowances.

    Alex is correct, but the difference isn't a lot, will you really notice 15lbs in the middle of the car?

    T5 (90A) is the lightest. Then 71C. Then 30A.

    Ah, I guess I was hoping that it'd be a big difference.

    Well I'll be damned, just found the info in an old thread:

    Guess I'll keep the 71C then.

    I'd wonder about the Z32's 30A, considering it's a bit shorter…
