S550 Mustang First Mods | 2015-21 - S550 Mustang First Mods | 2015-21

It is hard to believe that the S550 Ford Mustang model started over 6+ years ago. During this period the S550 Mustang received many changes especially beginning in 2018 in which it received the most significant revamp. It consisted of updates to the exterior, interior, and engine. These changes sort of made the S550 into two different generations in one due to the many significant and non-significant changes over this period.

In 2015 many changes occurred after the conclusion of the S197 Mustang. One of these moves was from a solid rear axle to an independent rear suspension. Also in 2015 marked the beginning of the EcoBoost engine as well as the 2nd Gen Coyote Engine. Horsepower for 2015 Mustang models ranged between 310-526 HP and in 2021 this number has improved from models having between 310-760 HP!

Many S550 Mustangs have been modified at this stage of their lives but if you get your hands on a stock, blank canvas car, this article will be the one for you! This article will examine the Best First Mods for S550 Mustangs!
