So yesterday I went through a few stages of grille blocks.

First off I made a top grille block by gluing glossed rubber to the back:

However after seeing some other blocks, I did a little bit of CFD and discovered that the blocked version still created turbulence and drag. So I decided to go for a full on cut to size and smoothed in version.

By the way this material is actually armoured mudflap rubber which I bought for my Subaru and didn't fit

I knew I'd be ecomodding this car, and now I'm REALLY glad I decided to get it in black!
