Re: What is the difference between LSD Ratios?

the math is quite simple, find the percentage difference between your current ratio and the potentially new rear end. Once you know that percentage, multiply the speed at any given gear/RPM by that percentage, and that would be your speed with the new rear end.

For example, 3.91/4.10 = 95.4%. If you are doing 3000 RPM's at 80mph with a 3.91 ratio, at the same RPM with the 4.10, your speed would be 80 X 95.4% = 76.3 mph, a difference of 3.7 mph.
