Thoughts on Drum to Disc Conversions…
Right. Because there are other things in this case that can make it an escalating project. Such as, the car will be used for long trips and with 4.5x5 bolt pattern on the fron and 4 x 5 on the rear, do you want to pack two spare tires? The 10" drums are OK for most normal purposes. Trailer towing or lots of steep mountain decents, and the better cooling of the disks will be an advantage.
With good linings, properly setup drums will stop fine on the highway. Its the repeated high speed stops where the heat can't be dissipated as fast.
