    Camaro & Firebird Fitments
    --------------------------------------------------------------------------

    Bolt Pattern

    5 x 4.75" or 5 x 120.65 mm

    Lug Nut Size

    19 mm socket (6 sided socket preffered over 12 sided sockets) 3/4" will work in a pinch.

    12 mm X 1.5 pitch commonly marketed as M12X1.5 - Recommend a "Bulge Cone Seat" style lug nut.

    Wheel Fitments

    The numbers in the columns are as follows:

    WIDTH ..... OFFSET ......... WIDTH OF TIRE

    Front and Rear

    7.0" ..... +35 to +40 mm .... 215, 225, 235
    7.5" ..... +35 to +45 mm .... 215, 225, 235
    8.0" ..... +38 to +55 mm .... 225, 235, 245
    8.5" ..... +38 to +45 mm .... 235, 245, 255
    9.0" ..... +38 to +56 mm .... 255, 265, 275
    9.5" ..... +38 to +56 mm .... 255, 265, 275, 285
    10.0" ... +38 to +48 mm .... 265, 275, 285

    REAR Only

    10.0" ... +38 to +54 mm .... 275, 285, 295
    10.5" ... +38 to +50 mm .... 285, 295, 305, 315
    11.0" ... +45 to +56 mm .... 305, 315, 335

    NOTE: 315 series tires DO NOT fit 9" or 9.5" wheels. It will not be discussed any thread posting will be edited, locked or deleted.

    PLEASE READ @ 315's

    Z06 Corvette Replicas:

    17"x9.5" +50 to +56 mm no problems. 275/40R17.

    18"x9.5" +50 to +56 mm 275/35R18 or 285/35R18.

    18"x10.5" +50 to +53 mm. Higher than 53 mm will require the BFH mod. 285/35R18s thru 315/30R18. Over 295 may require rolling the fenderlip and will need the BFH. +58 mm is the typical available offset for the Z06 replica, which will require a little BFH and/or a small spacer.

    Y2k Corvette Replicas:

    17"x8.5" +56 mm

    17"x9.5" +50 to +56 mm

    18"x9.5" +50 to +56 mm

    17"x11" Wheels

    ZR-1 Style for Camaro +50 mm (Known as Grand Sport offset)
    ZR-1 Style fo Firebird +36 or +50 mm The wheel well on the "bird" is a little wider.

    American Racing TT-2's +45 mm

    With 17"x11"s there is always a possibility of needing the BFH and/or fender rolling mods with 315s. If lowered, an Adjustable Panhard Bar becomes a virtual necessity. Some have used the +38 offsets with an 11" wheel but it does stick outside the fender and is definitly not recommended on lowered vehicles. +50 and +56 are the two most common. +50 is the better fit (for the ZR-1 replica).

    For road race only applications a 17"x11" at all four corners can be made to fit.

    I would go staggered in lieu of doing 11's on all four corners...
