    Hi Paul, I'm pretty sure the offsets are different. Check the wheels for the offset number.

    Here's a great offset thread.

    Ferrari in the end standardised on the same offset for the front wheels of Mondial t and 328 but the rears have a different offset but 328 rear wheels can be made to fit on a Mondial with a 25mm spacer.


    Mondial T wheels

    Front : 7j x 16 offset 50.8 mm
    Rear : 8j x 16 offset 51 mm

    328 ABS: 7" 38mm Front; 8" +63.5mm Rear

    Hi Paul,

    Answer: NO, they are not.

    The fronts rims of the "série 2" 328s (137079, after #76626) is exactly the same, including the 38,3 mm offset, as the 129791 front wheel of the "Mondial 3,2".
    These are absolutely interchangeable, which is no surprise as the front suspension of the "Mondial 3,2" and the "Série 2" 328s is interchangeable also (same triangles, or "A-Arms", etc...). However, just to distinguish themselves visually, the style of the dimension's markings on the rims: "Ferrari 7 X 16" is different, making these identifiable, but again: the two are fully interchangeable.
    BUT the 7 X 16 front rims from the "Mondial T" (Speedline 138857), despite looking identical to the others above, could not be substitued to any of the two above, as it has a different offset of 50,8 mm (vs 38,3mm)

    As for the rear wheels: no wheel can be substitued for any other, as the three have all different offsets:
    126949 for the "Mondial 3,2" (with tyres in inches, not TRX and mms): offset is 51 mm
    130905 for the 328 "serie 2": offset is 63 mm
    137087 for the "Mondial T": offset is 51,8 mm
    (although 126949 with 51 mm is really close to 137087 with 51,8 mm)
