Awesome new site, Sam! I can't imagine the amount of work you've put into this instead of your dissertation.
The Organization/Records tab output is wrong in many cases (Spirit, PiKA, Fringe, CIA to name a few.) I vote for this as #1 priority for raceday for the home audience.
Really minor stuff:
No design trophy count on the Orgs/Trophies tab? (At least my Spirit of Buggy made it.)
Could you have the "Make a Gift" link open in a new tab?
