If your primary concern is dirt/mud/rocks/etc. getting tossed up and damaging the quarters.....
Another option to consider is having the 3M Clear Guard, Or 3M Clear Bra material professionally installed.
Stuff works like a charm and you won't have the odd look(s) of any splash guards to detract from the overall appearance of your ride.
Not too mention the 3M stuff will save those quarters as well from any rubber material or other track related debris for those who race their Ecoboost's.
Just a suggestion of an alternative. Enjoy!
