big rear brakes, disc or drum, will lock up early because of weight transfer to the front/unloading of the rear wheels in panic stops. a factory disc/disc setup had literally hundreds of engineering hours in design and testing, where a disc rear upgrade is usually a matter of what fits. so you may need a disc/disc prop valve, especially in a racing or high performance/track application. I wasnt saying you wont need it, in fact I said you shouldnt need one. testing, thats where you will find out. and if you are leaving the wilwood valve in you will be well equipped if you need it.
