8.75 Strength?

What is this Mikronite you speak of and how do I get a set of gears with it applied?

I have a hunch that my 8 3/4 will be the weak link in my BB drag car.

If it is the rear isn't the issue its the parts or the labor. I know of many 10 and one low 9 second drag car running 8 3/4's. Ironicly the 9 sec ride is a camaro, lol.
