Why not purchase GOPRO and stick on car, then ditch the passenger weight. If you are going to drive all the way to Mexico to race, why not race with best set up? Weight equals HP does it not.
This is awesome. I have a local guy claiming all rights in our little hatch group with this same set up because "it's a super light car." This should shut him up even after explaining that his 110 trap speed wouldn't cut it.
