I may be over-thinking this, but regardless I'm curious about opinions on upgrading the 909.

Series completion PR is 65.1, and to achieve that you go to level 5 on Engine and Body (capturing the final two R$ upgrades), but then you have a choice of Drivetrain, Suspension. or Exhaust for one final GC upgrade to hit 65.2. Drivetrain looks a little more potent than Exhaust as a speed upgrade. The real question is more speed vs more grip, which one is better for this TT?
