Wilwood disc size question

[Gdub]

I have a 72 dart and running four wheel disc, I have the wilwood 12.19 dynalight pro series brakes front and rear. My question is that I plan to hopefully do some road course racing. Will this set up be good for my car? Or do I need next step up for brakes in front? Car will be mainly driver, full interrior around 3300lbs, triangulated four link rear, 6 speed, could over front rack and pinion and around small block around 350-400 hp, running 18s front and 19 or 20s rear. Road course won't be very often just open track days I would go race, with occasional auto cross.
