More progress... Got my third front panel installed, covering the entire engine subframe... Also got my front-mid pan installed...
There is an uncovered gap between front and front-mid pans, due to a subframe brace which I didn't deem feasible to cover... I also didn't want to cover the lifting brackets, for ease of getting the car serviced...
And it's not 100% flat and smooth, not sure what gains I can look forward to, maybe a little less engine load at 50mph? That's all I have tested, other than a high speed test to make sure it wasn't gonna blow off... So far, it's good for short bursts to 100+mph...
