Hi Doug,

I don't think that rear disks are the best place to invest when trying  
to add stopping power.

Basic physics will tell you that the weight transfers to the front of  
the van when stopping. The rear brakes will do less than 30% of the  
stopping; and that gets progressively less with your need to stop  
quicker.

Better tires (stickier rubber), better wheels (wider, for a better  
contact patch, lighter for less rotating mass) and suspension upgrades  
(stiffer to lessen weight transfer and improve handling) need to be  
implemented before the improved performance of rear disks will be  
noticeable.

Rear disks as an upgrade on an otherwise stock vanagon would be a  
waste of $$$ in my opinion; though they would certainly be worth  
looking at if all the above upgrades have left you with a below-par  
vanagon experience.
