EDIT here's a couple notes on the errors. Changes that affected the RX8 were correct so we now have open season on STX with 265s:

STX changes that would affect the RX8:
ITEM 14) Change 14.12.4:
“Rims (wheels):
2WD (FWD or RWD):
Width – 9” maximum
Diameter and offset – unrestricted
SCCA Fastrack News July 2008 Page 4
AWD:
Width – 8”
Diameter and offset – unrestricted
Tires:
2WD (FWD or RWD):
Width – 265 mm maximum
AWD:

SCCA Fastrack News March and August 2008
ITEM 15) Replace Section 14.12.7:
“Non-standard brake rotors may be used provided they are of equal or larger dimensions (diameter and thickness) and made
of ferrous material (e.g. iron). Aluminum rotor hats are allowed. Cars originally equipped with solid (non-vented) rotors may
utilize vented rotors. Cross-drilled and/or slotted brake rotors may be fitted provided all such voids are within the disc area,
and comprise no more than 10% of that area. Brake calipers and mounting brackets may be replaced provided they bolt to
the standard locations and the number of pistons is equal to or greater than standard. Drum brakes may be replaced with
disc brakes of a diameter equal to or greater than the inside diameter of the standard drum. Such conversions must be bolted,
not welded to the axle/trailing arm/upright. Changes to backing plates/dust shields/brake lines to accommodate these
changes are permitted but may serve no other purpose.”

I'm looking to campaign my '04 in STX in 2009. I'm thinking the new Direzza Star Specs are my best bet for a tire. Will 265s fit on the car? I thought we had trouble with 245s before. Goodness! Any idea on an appropriate aspect ratio?
I'm not sure about 17" vs 18", either. Hmmm...
