He suggested if I only plan to take it to a road course a couple times a year that a cheaper option would be to mix in 5 gal of 110 octane with each tank before track days. This would provide some extra safety margin and should only run me a couple hundred dollars a year.
Is there something I'm missing here? I imagine most of us will only track our cars a handful of times a year and just buying the race fuel as needed would make more sense.

The Toohighpsi system is around 2k. You should be able to get that with PI injectors, with JMS booster for around 3k.
Your engine isn't going to last long with boost on 93 with road course racing. So E85 could get you several more years of use out of the stock bottom end.
