I won a special award
I know what the differeneces are between the small and big bearing 9" rear ends. My question is, are there any performance advantages to using a big bearing rearend vs. a small bearing one? I have a 9" truck housing that I'm narrowing and building up to use in my Mustang. My disc brake setup is for a small bearing rearend. I would rather stay with the small bearing ends for cost, but will upgrade to big bearing ends if there is a performance advantage.
