GFR increases due to an increase in

GHP is the positive pressure while GCOP and CHP are negative pressures that determine the net filtration pressure (NFP).NFP = GHP - (CHP + GCOP)For GFR to be high, glomerular hydrostatic pressure (GHP) should be high, capsular hydrostatic pressure (CHP) should be low, and glomerular colloidal osmotic pressure (GCOP) should be low.
