If that FAQ doesn't help, try asking in the Tire/Wheel/Suspension forum. Remember, both S13 and S14 have a bolt pattern of 4x114.3mm. Don't be getting rims that have a higher-than 40 offset (the stock offset for the 240sx), they aren't made for a RWD car. Also, you listed quite a variety of motorsports there, each one has a particularily ideal setup. Try focusing on one or two areas, then look around. What size wheel would you like to get? Different sizes sometimes need different offsets to fit right...
