    Wheel to wheel surface measurements

    Finished mocking up both front and rear today (irs), took some measurements (unloaded obviously), with a rough 'alignment'. Can anyone sanity check / confirm this?

    Front, to the outside of the brake rotor, about 54 3/8. To the wheel mounting surface, about 56 1/2.

    Rear, outside of brake rotor, about 54 5/8. To the wheel mounting surface, about 57 5/8.

    I'm not sure how much deflection to expect loaded but my _assumption_ is it will be approximately equal front/rear.

    If anyone also wants to double check this math, assuming the above is correct:

    With front 18x9.5 15mm offset, rear 18x10.5 38mm offset, and the above measurements:

    Front rim distance out from mount: (9.5/2) - (.5/2) = 4.25
    Rear rim distance out from mount: (10.5/2) - (1.5/2) = 3.75

    Front total track: (56.5 + (4.25*2)) = 65
    Rear total track: (57.625 + (3.75*2)) = 65.125

    Sound somewhat sane?
