I have 2.73's. No complaints on my car. The Z spec T-5's ultra tall 1st gear when used in combo with the 2.73's makes it a little steep out of the hole though.

Most people I see with gears have traction issues. 4.10's especially.

none for me!!!
 

i am recommending the 4:10's and i have had no traction issues with mine.... of course, i drive on slicks or e.t. streets most of the time, but i dont spin at all on slicks and e.t. streets are the same thing. when i had drag radials, they didnt spin too much. well. good luck with whatever you go with.
