Although i installed the Steeda Clutch Spring several hundred miles ago, I've been waiting to post about it until I had enough experience to offer real world experience. There's several threads in the transmission/driveline section regarding this, but you guys might not see them.
I can absolutely, positively now say this is the best thing you can do for your 2019 Bullitt! For some reason, Ford installs a 185 #/in spring rate helper spring on the clutch pedal. My guess is it keeps the pedal effort down, especially at the bottom of the pedal throw. The problem is in the kinematics create a non-linear assist, and makes the clutch action not easily modulated; your left leg has to deal with the linear spring rate of the pressure plate plus the nonlinear spring rate of the perch spring. i've been driving manual transmission cars, bikes and tractors for more than 50 years, and the Bullitt clutch is one of the weirdest feeling I've ever experienced.
Steeda recognized this issue, and offers two solutions: the first is a replacement spring that has a much lighter 35 #/in spring rate, the second is a beefier spring perch kit along with their 35 # spring. I installed the more expensive perch and spring kit, but after comparing the OE Ford perch and the Steeda part I'd only replace the spring if I was doing it again.
I may sound like a Steeda advertisement - I don't work for them - but the change is so good every one of you should order one. Today. Removal of the OE spring/perch is awkward, but installation of the lighter Steeda spring is easy once you get your head down in the drivers footwell.
