SBP or BBP?

I just found that Firm Feel has shoes with "high performance" linings:

Firm Feel shoes

Does anybody have experience with this material in drums?

As far as the 8.75 rear end... I called around and the cheapest one I could find was 750 bucks. Too much money to pay for a core.

I am sitting on a few 9 inch ford units, and a quick look shows 2 of them with 5 on 4.5 flanges already. I have a brand new pumpkin with posi & 4.10's with 33 spline side gears under my desk. I doubt that 318 will break a 9 inch ford.

If I blow up 7.25, I will deal with it. I don't drag race, so it may be just fine.
