| from what I have in my mind...The design I like if similar to Strosek, with the exception that the part the meets the door line is gonna be smoother. A guy in Europe did what I would like to do with his widebody Z...He used the Strosek wide rear arches and smoothed them very nice right before they meet the door, so the finish you get is pretty nice and looks like factory...Forget about the extra vents he did to the car. 
Also, one thing that I like about the Strosek WB is that it's not the same wide all aroung the wheel...It gets lets wider on the lower part so it's easier to get it to look smooth with the door. Here's a comparition of the strosek vs. your style (marked in red)...Just so you can get what I try to say. 
Both are nice designs, but I think the Strosek design is a little easier for me to start with and get it to look smooth with the door.
