Terminology

isAccessory/isPerformance

Bit columns in product tables, isAccessory and isPerformance settings are for additional “non-stock” items, never exact replacement parts. isAccessory indicates “gift shop” style merchandise not directly affecting the vehicle - hats, shirts, etc. isPerformance indicates vehicle upgrades or products that enhance the vehicle, from upgraded exhausts and wheels to sun shades to polishes and waxes. A ballpark 95%+ of the catalog has isAccessory = 0 and isPerformance = 0. A product should only have up to one of these columns set to '1'.
