    Near as I can tell the California wheels are 8.5Jx19 F and 9.5Jx19 R. 599 pentagram wheels are 8Jx19 F and 11Jx20 R. Not even close to being a match. No clue on offsets yet.

    Skipper- If you look on the back of the wheel, it should tell you the sizes and offsets and maybe you can publish them here so we will all know. The car is so new, not much tech data is out there except for what the dealers have.

    I am afraid the California might use the 5x120 mm bolt pattern of the 612 and 599 vs the 5x108 mm size of the 308-430 cars. That may be on the back of the wheel, too, and will tell you if it will fit the earlier cars. Otherwise, you can just measure the diameter of the bolt pattern from the bolt hole centers. 120 mm = 4.72", 108 mm = 4.25", easy to measure the ~0.5" difference.

    also measured looks like the 108 mm = 4.25"

    Skipper- Will save that data. Worth trying on your 355. Will at least bolt on and the offsets are pretty deep, so might fit.

    OEM 355 wheels are 7.5Jx18, offset 46.15 mm and 10Jx18, offset 77.9 mm.

    Looks like you might have an offset match on the front and within an inch on the rears. Worth trying.

    Skipper- Might as well do the math. Not too complicated.

    OEM F 225/40 18 R 265/40 18

    (225 x 0.40 x 2) ÷ 25.4 = 7.09" + 18" = 25.09" F
    (265 x 0.40 x 2) ÷ 25.4 = 8.35" + 18" = 26.35" R

    (225 x 0.35 x 2) ÷ 25.4 = 6.20" + 19" = 25.20" F
    (265 x 0.35 x 2) ÷ 25.4 = 7.30" + 19" = 26.30" R

    Close enough at 0.187% smaller than OEM on the rears. Both Speedometer and ABS should be unaffected.

    where else could we verify the bolt patterns on the california wheels
    my tape measure looks like 4.25 but want to be sure

    i think ferrari started using a 110 or 111 mm on the california perhaps.
