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.

A front splitter would cause drag. Front diffuser to create an area of low pressure. Reduce the opening to the radiator and IC to slow the air down and make it more efficient. Reason why all these big power 1/2 mile guys basically have the front end boxes off
