Back to the car, I finally took some pics of the "finished" product this morning. I have the hubcaps off atm as my commute is in the city and they are 17 inches, 3 inches wider than the rims, so they sit flush with the most outward part of the tire, but cover the valves, so I'll just install them for my trip.
The skirts hold with 3 screws in each wheel well and black silicone adhesive.
I basjooed the front end using clear silicone and clear tape on the bigger gaps.
Nice ubolt dragging down eh? The pipe broke just after the cat yesterday, I'll have to fix that during the weekend, but will just hang it up in the meantime so it's not right in the middle of the flow for the first part of the trip.
