    Hi Guys,

    Getting some wheel adapters made and want them hubcentric. I need to know the DEPTH of the hub centres for front and rear but don't have access to the car, if anyone has this info it would be a fantastic help!

    I have the following info so far:

    FRONT:
    PCD: 5x108
    Centre bore dia: 58mm
    Centre bore protrusion length: ??????
    Stud hole size: M14

    REAR:
    PCD: 5x108
    Centre bore dia: 67.1mm
    Centre bore protrusion length: ??????
    Stud hole size: M14


    Thanks guys, Paul

    Measured from the brake "hat" surface on my 75 308 gt4:

    Rear: 8mm
    Front: 19mm not including the dust cap. Including the dust cap it's somewhere around 45mm.

    What are the center bores of the wheels you're adapting? What are the thicknesses of the adapters? That dust cap may or may not be a problem.

    -David

    Edit: These are all measurements of the car, not the wheels themselves but I think they are the measurements you're looking for. Let me know if I'm not clear.
