i'm gettin myself a mazda here really soon too and have been doing alot of research on them, b/c i am new to them..i've seen up to a 20 inch rim with a body drop..the correct wheel offset plays a big role as well. for the rear i've seen em all, 2 link, 3 link and 4 links as others are common. mine will be a 4 link of some sort, i'm undecided at this point..there is ALOT of useful info in past forum topics, i know b/c i've already spent hours looking, and there are alot of baddass mazdas in the owner profiles...check em out and have fun..and on yeah..there are some REALLY knowledgable mazda guys on here that will be able to help u out 10 times more than i can..a few would be russd, cris, rudy, leif and many others..hit them up, i'm sure they'll be glad to help..good luck
