I would do a grille block. In winter it's fine. Watch your temps. Use synthetics for engine oil and transmission since those keep temps down. Using some good quality extra heavy duty coolant will help in that department too.

If you wanna do more on aero, do a coroplast belly pan from old election sign if you have friends in politics. Then get some smaller mirrors.

Get a wiper cowl too...

Then you can get into friction modifiers for the engine, differential, wheel bearings using NMF and/or tungsten disulfide from lowerfriction.com

Have fun.
