Sorry to kick up the thread again but I an Altima Driver myself and seem to syuck in the 31-33 mpg area. I think the only gains I can make now are aero mods.
I was reviewing this thread and looking at:
-Lowering
-Wheel skirts
-Grilleblock (there sure are lotsa' openings up there)
-Mirror delete (it may be the pic, but they look huge)
-Airdam or bellypan
Does anyone have any recommendations on brands for lowering springs/shocks? I am also going to be removing the bumper and putting in the grill blocks? Based on the car above would you recommend filling in all areas? I was thinking the fog holes and top grille for sure, just not sure about the lower hole.
I also need to see if it is legal to do the mirror delete. Any and all advice is appreciated.
