A pillar must have an air deflector with vortex generators to improve flow avoiding flat surface drag.
The upper Air drag need more width to ensure flat surface drag is reduced (and reducing flat surfae for a curved air friendly one).
A Boat Tail will help a lot on lowering drag.

Nokian or Continental VancoContact2 tires with c.r.r = 0.0064 if is possible, Michelin Agilis crrr = 0.0071, with the same rubber, and width coefficents of rolling resistance is lower if radius is higher. Linear dependence is showed in european tests for ecolabelling tires.

Congratulations of your mods.
