(Turbo 2/4WD) Built for the (87-89) Mazda 323... ACT offers the 4-puck discs for Road / Rally / Drift or Drag Racing. The quick engagement is ideal for track use, but uncomfortable for daily street driving. Xtreme discs may chatter upon engagement when driven gently. Because of the non-dampened hub design, prolonged use (such as street driving) may cause noise and premature wear of drive-train components.
