Felony Diff. Fluids

[Dmkkings]

So I traded a RC I had laying around for a Felony. I will be doing Speed Runs with the car. The guy gave me two brand new bottles of diff. Fluids! He gave me a 60 mill. and a 500 mill. Not sure what diffs, to put which fluids in? Any recommendations would be much appreciated!
