I have tried the rims to Thunder Tiger SSB
the only thing about these rims is that the hex is a bit to deep, easily fixed using a flatwasher as a shim.
The price in Sweden for these is 8,59€ / 5,62£ / 11,19$ for all four wheels.
However i do prefer the "brighter" colour of the Kyo-rims over the paler (spelling?) TT rims.
