I'm thinking about/planning to replace my stock 11" Drums with a dual caliper disc brake system. I've narrowed my options to Strange and Aerospace and wanted to solicit some feedback/opinions on these kits from you guys. (I'm going with Dual caliper setup since I footbrake and also like to put most my braking to the rear when on the brakes at the finish line, rather than locking up the front runners)

Does anyone have any experience both of these kits and have opinions on which one is better or what you like about one vs the other?
