I've been inspired by all the posts I've been reading in the aerodynamics forum, So last week I started working on aero modding my Jeep. I decided to start with something simple, the front grill block. I'm only doing a partial block because here in Iowa it can get up to 110 degrees over the summer. I think I'm only going to fill five of the seven slots, and make two more for winter so I can do a full block.
So far i've got three done and put in.
