To answer the question if 20" wheels will fit or not, it depends more on the tires than it does on the wheels.
The stock circumference of the RX-8's OEM tires is 26".
That would mean that technically you need a 245/30 R 20. Only Pirelli Nero makes a tire with those dimensions that I know of. A 30 aspect ratio on a 245 tire is a VERY thin tire and is meant mainly for show. To prevent rim damage, you will probably need to run the tire at a very high PSI and ride quality will suffer.
The next best thing to do is to cheat a little and go with a 245/35 R 20 tire. There are a few companies that make tires of this size including the Bridgestone S-03's which are 26.7 inches in diameter. Your speedometer will read about 3% low because of the difference (i.e. at 70 mph your speedo will display that you are only going 68 mph)
If you really want dubs on your car, then the second option is really the only way to go IMO. Put those tires on a 8.5" 20" wheel like the one shown on Ebay and it should fit. You want to make sure that the offset is at least 40mm for them to fit without problems. The closer the offset is to the factory 50mm the better.
