Rear disc brakes:
1. Look cool
2. Lighter than drums
3. Less likely to turn mushy when overheated
Most people will never feel the difference on daily drivers, however.
Guess I'm a bit late to this party, sorry (I'm jammed right now). Another big advantage to 4-wheel discs: You lose the Bendix Duo-Servo rears, which are notoriously hard to modulate under near-lockup conditions. With Duo-Servo drums on the rear -- which have wildly varying, nonlinear, line pressure requirements -- correct F/R proportioning (crucial to short stopping distances) is a constantly-moving target.
On the tall knuckle deal, 2 quick points:
> By actual measure, the bumpsteer is tripled if you use this to replace the standard knuckle. (The longer design was specifically needed on '73-up Bs, and F/J/Ms, because the UCA mount had to move up when the K became rubber isolated.
> Warning: Some repops are CAST IRON. I have heard (from vendors!) of wrecks because of catastrophic failures.
