Those SSR's are very very nice. If you want something lightweight and Japanse your more or less bound to the bigger manufacturers i guess, rays, ssr, advan, enkei and wedsport, something forged. Wedsport has a crazy wheel, 18" and under 3kg: I don't even want to know how much it is though I came across a set of wheel today for sale in Holland which i have a bit of a softspot for, Work Leadsled: Perfect offset and width, only i'm not sure they will work on the Glanza.
