All this talk of rear disc brakes is crazy! Fact, the front brakes of a vehicle do about 60 to 70% of the stopping. So if you want to stop faster you really need to clamp on to the front disc better. Right now I bet you CAN'T lock up the front wheels as you don't have a big enough clamping area and a big enough master cylinder to apply the necessary pressure. Also, you NEVER want the rear brakes to lock before the front brakes. The issue with the Small Car setup is that there is no brake proportioning valve included. They say the rears never lock before the front... I would like to know how they tested that? Was it on loose gravel or an ice covered road or was it just slamming the brakes on a tarmac road? If your rear brakes lock before the front brakes, the rear of the van will begin to slide and you will have a messy situation on your hands. You NEED a brake biasing valve in the system if you go to rear discs! I think everyone wants the rear brakes as they are sexy and give the van a sense of "bling bling" I think getting the rear drums media blasted and then powder coated makes them look pretty sharp. Installing some 280mm or 288mm Audi brakes on the front with a larger master cylinder will make the van stop on a dime.

Given a heaver rear end with a larger Subaru engine in a Syncro, and wanting more stopping power, which is smarter to do first? 1) Upsize the now-stock front disc brakes or 2) Put discs on the rear?
