Currently running a 4.11 rear end gear.
My trap speed is 127 mph.
A999 with 1:1 3rd gear.
29 inch slicks.
My rpm at the finish line is 7200 rpm.
Would like to lower my rpm to around 6500. What rear end should I use?
I tried different calculators, but when I plug in my numbers, the current gear ratio is way different that what I have.
Hence the reason I am asking for some guidance to figure out what rear end ratio to purchase
