    Wheel bolts are a function of the wheel for a given model, not the car model itself. Of the 90s era cars, the 456 and 355 use slightly deeper bolt seats and longer bolts.
    550/575 (All OEM18/19in wheels): M14 conical bolts of 52mm shaft length, 60 deg taper
    456/456M (OEM 17in wheels only): M14 conical bolts of 55mm shaft length, 60 deg taper

    (AKA if your running 575 wheels on a 456, you technically should use the 52mm bolts as you risk not fully seating...I discovered this when I mounted modulars on my 456)​
