I installed Strange discs front and rear on my drag-only car. I was told by Strange and others to put the prop valve on the front brakes due to the small front/larger rear tire combination. Also put it before the line-loc. But I seem to remember Strange saying that if I were to use drum brakes out back, put the prop valve in the rear. The deciding factor might be if you are running skinny tires up front,in which case you may want to limit the braking power to them. If your discs are aftermarket, I would check with the manufacturer.
