Just got it all done, made the side plate and painted to more Mini Challenge style look, and I able to made it so will clear the antenna when the boot open. here some pictures what you think

 

nice job on those end plates

 

Very nice keep up the nice work it just fit the Mini like a glove..nice set up..

 

I like the look of it being lower but I wonder if the spoiler/airfoil is really seeing that much clean airflow. The roof on the mini has enough of a curvature to lift the envelope slightly. Granted I dont know if you were really going for pure performance. If you liked the lower look it would be best to move it farther back I would think. But honestly, great execution.
