While I'm thinking about it, it's very common for people with a 4.389 FD to want to swap out for a 4.7 or shorter. You can probably find oodles of 4.3's for next to nothing on forums and eBay. Definitely less than a new 4.0, and still good for an 8% reduction in RPM.

Fun fact: TSX gearbox WITH a custom 4.059 final drive has similar gearing in 6th gear to the Insight's 4th gear. TSX 4th gear is equal to the Insight's SECOND gear.
