What to do first?

recently picked up a 1969 Dart, 340 w/ 4spd. In no particular order, I'd like to do a motor and train rebuild, an RMS front suspension - maybe rear as well, disk brakes front and rear, and new wheels/tires to go with it.

What I'm looking for input on is what order to do these things. My initial thought is to do the brakes and suspension first, so the car handles when more power is added with the new motor/trans. Nothing wrong with the suspension as it stands today, so I could do motor and trans first if I wanted to.

Looking for feedback and considerations on what to do first and why. Thanks in advance!
