I know, old thread but hell I am in the same boat! Got a 2dr 6 speed too and need to decide between 4.88s and 5.13s...eventually moving to 37s too. I originally wanted 5.13s but now am thinking about going with 4.88s because the teeth are bigger and stronger? Is this right? Thoughts on the teeth side of things?
And yes I have seen the chart...more interested in the teeth question.
