Yes, you will need grounding rods in addition to a wired ground wire in the feeder. You need 2 grounding rods at least 10′ apart. Do not use a 60A panel in the garage; they have too few spaces in them to be useful.
Does my detached garage need a ground rod?
Yes, you need a grounding electrode (ground rod) local to the detached building. Connecting to reinforcing steel in the slab would have provided a very good grounding electrode, but if it’s already poured, that ship has sailed. 6 AWG solid is the default minimum size for a connector to a grounding electrode.

Household electrical systems are required by the National Electrical Code (NEC) to have a grounded system connected to earth ground via a ground rod. The Ground Rod is usually located very close to your main electrical service panel.
Why are 2 ground rods required?
If it has a ground resistance of 25 ohms or more, 250.56 of the 2005 NEC requires you to drive a second rod. But many contractors don’t bother measuring the ground resistance. They simply plan on driving two rods because doing so will meet the requirements of 250.56, regardless of actual ground resistance.
How do you hook up a subpanel to a detached garage?
Dig an 18-inch deep trench for the outdoor electrical wire, which you will run from the main panel box to the garage sub panel. Use 1 1/4-inch PVC conduit for a 100-amp sub panel or 1-inch PVC conduit if the sub panel is 50 amps or less. Run the conduit from the garage to the main panel box.
Can ground rods be shared?
