Lowering the car 1" significantly decreases drag and lift but it will still be a factor without a front splitter and removing area of high pressure. The hood vents remove the highest area of high pressure, the next place is the fenders. There is a reason all racecars have a way to remove high pressure from the wheel wells.

Another thing is I may have caused my own problems via adding brake ducts, Zspeed undertray, air direction panels that were removed due to TT install, and Tracspec vents. It may be due the increase in TQ causing more weight transfer. I don't know and that is what I am trying to figure out.
