I have a new xb8ec and Mikes conversion kit coming. I was planning on putting a 1521 in it but I figured its extreme overkill and I wanted just plain overkill...
. I was looking at the 1515 but cant decide between the 1y and the 2.5d. I want to run a 6s but doubt I will go more than a 5s. I need some opinions on this setup.
I might also run a truggy ratio with the active diff whenever it comes out for the xt8.
