I wasn't aware of a front splash guard for the GT350. Thanks to another GT350 owners recommendations, I added these rear quarter panel protection film, and added the additional protection directly in front of the rear tire.

These look good. I got the Steeda because of the price, I would have consider the BMR but they were about a $100 dollars more. $100 could go to my hood struts :)
I'm just cheap.
I had a call from my dealer this morning and I was told they had received the parts and are going to install it today. My car was on recall hold when I purchased it.
Hey 50, thanks for posting the detailed build thread. I just started following it today, and its been very helpful for a noob like me to the Mustang community. Keep it up man, and the car looks good.
