You will only need the right side UPR, unless you are constantly tracking or racing the car. For normal driving and occasional track days the right side only is fine, the left side will not collect any oil.
I went with the FP version to keep the factory look and simplify the installation. The unit works great but the main issue you will read about with the Ford Performance unit is about removing the oil that is collected.
It is not a big deal, just remove 4 easy screws, pop the cover and use a large syringe to empty the chamber. It takes all of about 2 minutes. I use my vacuum brake bleeder to remove the oil, then I can measure the amount on the spot.
