The mixings of dR quarks, hidden from view in the standard model (SM), are naturally the largest if one has an Abelian flavor symmetry. With supersymmetry (SUSY) their effects can surface via \stackrel\ifmmode \else \~\fidR squark loops. Squark and gluino masses are at TeV scale, but they can still induce effects comparable to SM in Bd (or Bs) mixings, while D0 mixing could be close to recent hints from data. In general, CP phases would be different from SM, as may be indicated by recent B factory data. Presence of nonstandard soft SUSY breakings with large tan\ensuremathβ could enhance b\ensuremath→d\ensuremathγ (or s\ensuremathγ) transitions.
