Please no crazy comments on this one just a heads up. So i am thinking about 4.56s in the TA. Keep in mind she is no trailer queen but is a track based car for the most part. In fact other then going to a show every now and then and to the track she doesn't leave the garage that often. What do you think play it safe with 4.10s or go all out

 

What are you running for a Tranny? If its a 6sp, my opinion would be 4:10's, if an auto, go with the 4:56's. Simply being that with the 6sp, your probably already traction limited in first and second. I have 3:42's in my 6sp, with probably much less mods than your car, and I cant hold my 325/30/17s down for first or second gear. If its speed you want, and its a track car, go for gold man, your not a newbie, so we dont need to tell you how gears work

 

id would say since it is a track car you probably have a set of slicks for it. with the slicks, if you build a bullitproof rearend you should definately go for the 4.56s. if you have a decent amount of power pumping out you will probably jerk the front wheels a few inches. i believe if you have the auto it comes with 3.23s and the manual comes with 3.42s. another good idea for a strip car is to replace you 7.5in rear and put on a ford 9in. many guys have a problem with putting ford parts on their cars but the bigger gears you can get the more durable they will be.

 

The car is a auto and does not have traction issue's thanks to some good rubber and a set of 15 inch prostare's.I dot expect the transmission to hold very long but we have something for that to .

 

ANY ONE ELSE[>:]

 

Before jumping in with my $.02, I need to clarify something first. Is your car a "track" car or a "drag strip" car?
Not tryin to split hairs, but when you refer to a "track" car, generally you're talking about racing on a race course "track" (combination of straights and twisties). So it makes a difference on what gearing you use.
Yes, I know this is the "street/strip" section, but there isn't a "street/race course" section to otherwise refer questions to.

 

4:56s and if traction becomes a problem u can always fix that

LOL a very good point. But yes this is no auto x or road course car [>:]. Once the transmission lets go i will be sticking with the RPM built stage 5 4L60 so i will be keeping 4th gear

 

I'd go for the 4.56's, I was going to put a set in my six banger before we bought the mustang.
