Rear Diff Setup Questions
So I have been working on moving everything over from my 96 GT/Cobra to a 2002 GT. I bought the 2002 GT as a roller. It has welded axle tubes, moser 33 spline axles and a full moser spool installed. Either has 3:73's or 4:10's (Still have not looked to see which)
The diff setup in my GT is just basically stock with 3:73 gears.
The car is my weekend warrior. Since installing the KB 2.1 2 years ago, I may have put 500 miles on it. It has hit the strip once. At the strip, I had HORRIBLE traction issues. I run 275/40's but they are just street tires. I also have Hotchiks LCA's and Tokico shocks on the rear. On the street, 1st gear for sure is pretty scary, and 2nd i unpredictable.
So I am up in the air on what I want to use. The car is 99% a weekend warrior that will maybe see the strip once or twice a year. I for sure want to keep the axles. Should I keep the spool or should I sell it and install my parts int he stock rear diff?
I don't know much at all about rear diff's. My buddy is an ASE mechanic and installed the 3:73's years ago. Labor will be free. Just wanted to see what everyone thought. I know for sure I want and need more traction both at the strip and on the street.

Traction issue solution= Run a heim joineted control arm setup with adjustable uppers, set pinion angle at -2 degrees, make sure you weld and reinforce torque boxies, run a stock v8 rear spring cut 1 coil, strange 10 ways front and back, and a good tire. (with some sidewall)

Interesting. I guess I am going for a couple gains here. A bullet proof rear diff and more traction.
uberstang, thank you for the info. I will make sure to save this off and reference this when the money allows me to upgrade. I have read nothing but bad things about aftermarket UCA's. Not debating what you say by any means, as you obviously know more on this subject than I do. Just thought that was interesting...
Torque boxes have been welded and I also have a swarr bar which I forgot to mention originally. I have eibach springs but I assume that the stock springs would be softer and would achieve the drop by cutting them. I have strange 10 way coil overs up front, but Tokico's in the back.
It is kind of a freak of nature car. I have basically taken 4 mustangs, kept the aftermarket parts from them, sold the rest off the parts off and am building one lol.

Theres a huge debate about pinion angle and launching a drag car. One camp for it and one camp against it, it can be argued untill the cows come home. But as far as a mustang with a 4 link suspension setup its been proving time and time again setting the pinion angle correctly and making sure you have a good instant center= lower 60 foot times. I'm not exactly sure its the pinion angle in itself that makes the difference but a change in pinion angle changes the suspension geomety and angle of the 4 link components and also aids in binding problems with the rear joint of the driveshaft. Its hard to explain and like I said people will argue about it, but the bottom line is people see results when properly adjusting the pinion angle.
