Brake combo question

[1985olds]

I have an 85 cutlass with a 5 speed manual 327 and 4.10 rear gears. I am doing a budget 4 wheel disc swap. So far my plans are as follows belltech 2102 lowering spindles with a sealed hub, 13 c5 rotors and c5 calipers up front, and lt1 rear 12 inch brakes and calipers. I need a parking brake for street use. i was wondering what the more knowledgable members here think of the combo, is it balanced enough, can it be improved, what are the pros and cons etc? my main concern is everything working in harmony. Thank you in advance
