Copied from the GCR:
Subframe braces may be updated to stock 1997 configuration
utilizing the MAZDASPEED Motorsports Development Spec
Miata kit. 2001-2005 (VVT) model years must remove the
additional intermediate underbody/floorpan attached bracing
(Mazda part number N067-56-G11A Base plate & part number
N067-56-H10A cross member).
This rule was written befor NB cars where allowed. A change should be made via errors and omissions to specify that this is for all 90-97 cars.
Change to "Subframe braces on 1990-1997 cars may be updated to stock 1997 configuration ..."
Maybe cousin Jim can get this done easily
