I only have the rear diffuser for now as I'm still undecided on the front splitter, though it would take little arm twisting to push me over the edge
.
I'll need more fill ups with the diffuser to get an average mpg with the diffuser so I can compare the 2 averages and not just a single fill up. I averaged 26.3 mpg before the rear diffuser install. According to my fuel app, I got 25.7mpg on my last tank before the diffuser install. The one and only fill up after the diffuser install came out to 28.3 mpg (my best so far) which is where the app got the 2.6 mpg difference. Once I get more fill ups with the diffuser, I'll be able to better compare the 2 averages but the initial data is already confirming the claims made by Velox of reducing drag.
