20b Gearing Question?
What do most of you guys run for your final gear ration (rear end). 3.90? 4.10? or if you have an 8.8 ford do use the 3.55s? The cobra one I have has the 3.55s, should I stick with these or go lower? say 3.73, or 4.10?? or would I not stick? Motor is a street port with a GT42R.

If it's a daily driver on radials making over 550rwhp then stay with the 3.55's.
Just took a drive in a 678 rwhp car with the same gear and traction on drag radials was almost perfect. Might even go down to 3.27's to see what happens when the power is up in the 800's. Just love how easy the cobra IRS swap was.
