Q: What is the difference between the High Efficiency and High Downforce options?

The High Efficiency version is tuned to cut drag while adding some rear downforce. The High Downforce version adds a gurney flap that raises downforce significantly; the flap trades away some efficiency but nets out roughly drag-neutral despite the much higher downforce. Pick High Efficiency for range and stability, or High Downforce if track grip is the priority and you can accept the tradeoff.
