This a great look. Very unique in a "Taking care of business, No BS" manner. What are the wheels and their specs and how was the car lowered (springs or other suspension mods) and by how much? It looks as though the tire diameter is around 26.2 " (similar to stock) so your speedo should be accurate. Do you know how much of a hit you took on efficiency?
I am running Mountain Pass sport coilovers set to their recommended height.
Tires are 265/40/18 which are 26.3" which are the same as the stock 235/45.
I saw a minimal change in efficiency. My average over two seasons was 265wh/mi. Michigan is pretty flat and I'm ~95% highway.
