I run Koni Str.t and Steeda Ultralites (not Sports) on my Coyote. They are, without question, the best ride quality setup I've ever felt in a lowered Mustang. Period. Even with 20s and rubber band tires.
Absolutely fantastic for a daily driver like mine. Plus, they lowered the car only a little bit (1" front, 1.25" rear) so I can still get over speedbumps with ease.
I think most people WAY overestimate how much shock absorber they "need." Unless you're at the road course doing something serious, anything super fancy/expensive is way overkill and just wasting money. IMO.
