I have 3.46s in mine(also auto) and it wakes it up a bit but if I could do it again I would go at least 3.7s. If you don't do a lot of highway driving I don't see 3.9s as being too bad. Also a mate of mine Got his diff done at Diffs2u and they f ucked it 3 times. He ended up towing it to trans gears and Diffs to redo the lot

Yeah not a great deal but for the money you'll wish you went 3.7s.

3.46s will sit at 2000rpm at 100ks not sure about 3.7s, maybe 2200. Just going by my experiences as I wish I went a different ratio. 3.46s may be fine for you tho I think 3.7s in an auto are good allround.

Diffs2u are sh1t! Go to a proper diff place and def get 3.9s or 3.7s at a minimum! Heaps of ppl run 3.9s in an auto!

If you plan on keeping the engine stock run low gears like 3.9 if you plan on making decent power don't go under 3.7 even 3.46 with good power will just wheel spin everywhere. We do ratio changes and tend not to go under 3.46 unless manual, that way you can use 6th gear
