I only have four 14" wheels that fit the car, so I had to do the 2 and 2 approach.
Good point about gear ratios: the 15's on the rear would have been spinning the diff/transmission 7.5% slower than the 14's. So, some of the apparent rolling advantage of the 15's was from decreased driveline drag.

More comments from strangers
Brief conversation today at a stoplight...
Guy in SUV: "Excuse me - what are those discs for on your wheels?"
Me: "What's your best guess?"
SUV: "Well, they say 'eco-something' on them, so I'm guessing wind resistance?"
Me: "Exactly."
SUV: "So they save gas?"
Me: "A tiny amount"
SUV: "Is it worth it?"
Me: "It all adds up!"
SUV: "Last question: are they expensive?"
Me: "Nope - I made 'em!"
The light changes and we part ways, and I'm wondering if he'll be trying to find "eco-something.com" on the interwebs later. I also wonder if he asked about price because he liked them? |

thats why a 28´ bike rolls better than a 26´, less rounds for the bearing. |

C.a.d.
I've progressed from paper templates to Cardboard Aided Design for the fender skirt...
And I wonder what will happen first: get the cardboard skirts on, run out of good weather... |

I wonder if he thought they were carbon fibre (because flat black)? CF = desireable!

Are you producing the bumper line straight down? What will the back edge look like?
