4.10s will run out at about 114mph. Keep that in mind. For na they work well for PA with stock Rev Limiter not so good.

I love the 3.90's on my fox, but if I had a 99-up, I would get 4.10's without thinking about it

Also 3.90s are an option, but I would go with the 4.10s and pay with tire sizes to get you to the 3.90 gear.

I used to have 430s on my 2001 gt,,It felt great but I went lower to 373s. You need to make sure what u have in mind for your car in the future,,because if u add nitrous or a SC then, maybe you shouldnt worry about having such step gears. [Wink]

Maybe if you had paid attention you would have (or have been smart enought) to notice Don was talking about quarter mile where you only used up to a 1:1 ratio that being 4th gear and the stock rev limiter being the restriction.

Still 114 is good enough for mid 12's if not a tad bit quicker.
