Me myself, have saved any go-fast building for the Zetto, and have just converted the daily driver into Low 'N Slow mode.
Only other real plans for this thing are a custom front lip, the rest of the TRD body kit, new spacers, more lowering(!) and skinnier tires to accomodate pushing the wheels out to keep them from ripping fenders. However, I'm also considering refinishing just the front faces of the spokes of my Meisters (leaving the sides black/lip polished, and copying another WORK Wheels finish: Black Clear Blue
Hmm....should I? After this, it's full steam ahead on all things Z.
