SSBC Aluminum Calipers Va. OEM 14" steel wheels?

I should add that the car already has QA1 shocks and will shortly have QA1 UCA's, dynamic strut rods along with greasable poly pins. It has 60lb of linotype lead in the rear bumper too lol. Car is sorted out on scales when changes take place.

In the end I want to keep the stock style front brakes, spindles and LCA's. If I go 4.5 bc in the front I am afraid it will open a can of (buying new wheels) worms.
