Agree that just changing to 73mm front caliper is not the way to go. Really need to upgrade as a "system".
One thing that article did leave out is that with larger calipers and stock MC, it would be easier to modulate
the threshold braking limit, due to the longer pedal travel (again as mentioned, if you don't bottom out travel).
Ford did the S197 PP front 4 piston brakes with no other changes (hydraulically). I did it on my 14 and hated the extra travel.
Yes, once you got "braking", it felt like they worked better, but pedal travel was increased by a decent amount
(which my personal preference, I hate). Many liked it on a road course, as the travel was increased, allowing better modulation.
On the street. I actually prefer going the other way. My Capri has stockish 87+ front brakes (and older FMS rear disk kit).
I put in 86 SVO MC to get less brake pedal travel. One thing left out in many brake system "analysis", is how long it takes
to actuate brakes before anything happens. @ 100 MPH, even .1 seconds is an extra is 15 feet (before any braking even starts).
I highly prefer low effort, very short travel brakes on the street.
