Gearing is a good question. What is minimum gearing for 33s? I've got the crappy 3.07s on my AX-15 (manual trans) and don't know what to expect with 33s. Any thoughts?

My guess is the 33s will make a little more of a difference with torque and gearing. I'd probably suggest swapping to 4.10s just to be on the safe side.

70 x 3.07 x 336 / 33 x .79 = 1728.57 rpms at 70 with 33 inch tires
70 x 3.07 x 336 / 28 x .79 = 2037.25 rpms at 70 with 28 inch tires
I gave you the rpms for 28s as stock that is what is on mine. There is a difference of over 300 rpms, you can use the formula to figure out what ratio you want to run.
