The body and wheel create their own independent supervelocity at the suspension junction do to their displacement,so the air here is faster than ground speed.
From Hoerner's bomb and drop-tank drag data,the best you could do would be the 'pylon' or 'Chute' style fairing around the naughty bits,as with Sylph and Edison 2.
Leading edge radii and junction radii can kill the horseshoe vortice drag component of the junction drag.Otherwise,we just have to live with the result,unless we enclose the whole thing as Mercedes found to be superior before WW-II.
