Aerodynamics: (After main powertrain has been completed)
Remove factory flares and steps.
Cargo area roof replaced with aluminum “sloping bedcover” style hatchback shell. Body sides will taper in to stepside tailgate. Should look like an Avalanche with an aeroshell.
Aluminum belly pan/skid plates and aluminum replacement bumpers. Bumpers will incorporate a non-destructive “crumple zone” with some give (for safety and durability reasons).
Appropriate grill blocking and engine airflow channeling.
Conveyor belt tire spats.
Probably other rearview mirrors.
Factory smooth wheelcovers.
