My plan for tuning the VG was to make a full width version and experiment with its fore/aft position in relation to the upper back glass seal until tuft testing showed attached flow down the back glass... However, given that profile picture, it appears that I should be building a partial kamm-back... I already have done an air dam extension and rear tire spats, but I don't have hubcaps, just the plain steel wheels... Future plans are lowering at same time as strut replacement(by means of cutting small amount from spring), adding at least a partial undertray, rear wheel skirts, grille blocks, and the kamm-back on the roof...

The end goal is to have a car that is still aesthetically appealing, and can achieve 40mpg highway with cruise set and A/C on if applicable... Given that I set my cruise at 80mph, that's a tall order, but nonetheless it's my goal
