so it's not a tested diffuser (as most diffusers), but I'm pretty sure it does a great job as a diffuser since we have followed design cues from proven diffusers...Also, people would need to make a custom metal sheet or something that goes underneat the car to make a better use of the diffuser. If the diffuser was a tunnel wind tested product, believe me you wouldn't like the asking price at all!!
