    To my understanding, the "tight" was refering to backlash... like I didn't have enough backlash to account for thermal expension. And as stated above, it may be thru for racing, but OK for normal road driving. As I intend to track the car, I will increase the backlash a bit, still within the TIS spec.

      This.
      To me it looks like the pinion's too deep.
