Also, I noticed in the pictures the Challenge lip attaches from the top, the bottom of the lip extends a couple of inches under, then just stops. I wonder if this will create air turbulence under the car. I hope not since i periodically track the car.
The front lip will have an air dam effect blocking air from hitting the front edges of the wheels. The GTS lip also ends after its front leading edge with positive downforce results, so you should have any worries about negative effects in any way. The rest of the front oem undertray is retained still.
