tuff call, if you dont DD, have fun and run 4.10's and you could always get a taller tire if you thought it was too steep with the tires you have on

98Z,A4,4.56s',DD here.
what is it with the 3.23s' that is 'killing' you?
3500 stall should get you up in the powerband quickly. 3.73s or 4.10s will improve your acceleration and decrease your traction. If it's not a DD,the 4.10s' will make 1st & 2nd wicked,providing the tires will bite,and as stated by a previous poster,going a larger dia. tire will change your 'effective' 'felt' ratio.
I went from 3.23s' to 4.56s' 3 yrs. ago and never looked back. Even took 3 trips to Florida from Cleveland,Ohio with the 4.56s'.

Like said here. You can always meet halfway and do the 3.90's. IMO I'd do the 3.73's if it's not a track car. I love my 4.10's but hate it on road trips and driving around. My car is a track car though so I don't drive it a lot. The 4.10's are a lot of fun though.

I went through this decision a few weeks back. I split the difference and went with 3.90s. However, I have a 27" tall tire. For the record, I only plan to have a trap speed of 110 to 112. I used the drag race calculator to make my decision:

changing 3.23s' to 3.73s' will increase the torque to the tires by 15%.
changing 3.23s' to 4.10s' will increase the torque to the tires by 27%.

I have 4.10 with 4000 stall H/C. I dont daily drive it but could minus the winter.
Around town it is fun as hell maybe a 4.30 when i do my rear end upgrade. If i had to drive on the highway or interstate at 65-75 mph for more than an hour to get to a track it would be okay but that part is up to you. Some can tolerate it some cant. I have read most going with 3.73 and saying you wont be happy with 4.10, After my install from a manual i dont think the 4.10's are that bad based on my intentions with it, so it comes down to what do you want?
