    Hello,
    I'm currently looking at ordering some new wheels for my 348tb and the wheel manufacturer requires some dimensions.
    I will only be putting the car on a lift in over a month and would like to order the wheels ASAP.
    Would anyone be kind enough to help me fill in the following dimensions for the front and rear brakes?
    I looked with a vernier and measuring tape with the wheels on and was able to get these rough dimensions for the front, but I can't get most of the dimensions so I gave up (I can't jack the car up and remove wheels at the moment).
    Any help is appreciated! Thanks in advance.

    Front:
    A: 30mm
    B: 120mm
    C: 155mm
    D: 180mm
    E: 67.1mm

    Takes only 15mins to take the wheel off, measure and put it back on
    I can do that tomorrow
    How accurate do you want the dimensions to be
    I only have a caliper and a ruler so +/- 1mm is the best I can do

    Thanks Frank, that is VERY kind of you!
    Trust me, I love doing this kind of stuff but my current formula of a very tight garage and pulled sciatica doesn't add up too well. +/- 1mm is perfect for me.

    Luigi,
    Here they are (348TS 1991)

    FRONT and REAR:
    1) there is no diameter F, so G and J do not exist
    2) E = dia 67.0
    3) R = 0, there is no radius since this is the brake disc sliding over the wheel mount

    REAR:
    1) G = 7.9
    2) D = 180, C = 155, B = 115, M = 105, K = 40, L = 5
    D, C and B are difficult to measure but these have some safety
    3) the disc base has a dia of 190, there is a small recess of 0.7mm at dia 145
    4) A = 11

    FRONT:
    1) G = 10.8
    2) D = 180, C = 155, B = 115, M = 100, K = 40, L = 5 same remark as rear
    3) disc base = 160 to 161
    4) A = 32 (you measured this as 30)

    Hope this is sufficient
    Took me a bit longer than 15 mins :)
    Frank
