As for brake upgrades, I--myself--would have to actually drive the car before accepting another's judgement. Almost as bad opinion on what accelerates and and what doesn't accelerate, many people cannot tell what stops the car and what doesn't stop the car. (If I didn't detest wrenching so bad, I'd consider going into the fgf drum brake repair business.)
Also, you have the idiot factor behind drum brake overhaul, whereby people haven't ever experainced a correctly operating set of drum brakes. If the car won't stop, a jury rig might make the car stop better. The thing is that the jury rig set up might stop the car better than the defectively repaired drum brakes, but they aren't stopping the car as well as properly operating drums.
