Decision: 5x4 (SBP) or 5x4.5?

I run stock bolt pattern 5 on 4 cause I like steelies and dog dish caps, I have 10 inch drums and Kelsey Hayes disc brakes on two separate cars, the ten inch stop better but the discs don't require adjust and get hot with a lot of use. If you know how to drive you should be fine. My brothers car has the big bolt pattern disc which are better than both set ups I have.

If your up for it, see if there are other linings that provide the braking more to your liking.
I've experimented every time I've not been fully satisfied. Porterfield's street lining works pretty well for both disks and drums (currently what is on my Barracuda). A few of the guys here have really liked EBC Red stuff for the disks. D11 pads as you prob know. Like most of those types of materials, clean the rotor and bed in per recommendations. That still leaves the rear shoes to figure out. Rear is real important for how it feels and responds on the initial application.
Most replacment shoes and pads have edge codes with friction ratings. Its a very rough rating system but its better than nothing when comparing.

Getting off topic here so we can take this to another thread if anyone wants to keep discussing.
