6AWG copper wire would certainly be the minimum because that a 60A subpanel however with a 105ft distance you have too lot voltage drop and need to go as much as 4AWG copper to save the voltage drop within acceptable boundaries (usually 5%).

The National electric Code publication / write-up 110.14 (c)(1) identifies temperature limitations for circuits and feeders of 100 amp or less. If the circuit is 100 amp or much less you have to size the conductors based upon the 60-degree celsius pillar unless the breaker and also the devices terminations space rated for 75 or 90 degrees.

You need to use a #4 conductor to feeding a 60 amp circuit.
