Thoughts on Drum to Disc Conversions…
Its 2022, so the average vehicle made in the last 10 years can do 60-0 in about 120ft, some more performance cars are around 100ft.
You have a good set of stock 73+ style brakes with good pads and decent tires, maybe you can modulate your way to 130-140ft from 60. Makes it pretty safe, and they have some repeatability if you have to do more than one stop.
You have drums on all 4, they might get 1 stop in the 150ft range, if you can keep it from locking. Then up and up from there. Even the best ones probably have very narrow tires. Might be the difference between plowing through another car and not. I had perfectly working 10" drums and if you really needed to stop it would basically just skid the tires because they were 195s on tiny rims and they are more difficult to module. Even the stock disks (and the wider rubber) saved my car from hitting a few deer over the years as well as from people driving like jerks on the road. This was even when I had stock disks and 225's.
Now I have Dr Diff 13" Cobra Fronts and 11.75 Cobra rears and now I have to worry about getting rearended...
