Gears

I have 35s right now but I'm stuck between choosing 4.56s or 4.88s. I'm not sure which ones to get so can some one give me some positives and negatives about them

With 35's, the 4.56's are just about right. Of course if you really want to "wake it up" the 4.88's will do that.

Probably not given the heavier tire but depending on what your factory gears were you might lose est 1-3 mpg from what it is now.

It should actually go up. You won't be "lugging" the engine.
