I noticed that some of the road race guys had completely removed the "frame" in the hood of their Civics and CRX's. Basically, it's only sheet metal, the whole supporting grid of steel is gone. How did they do this? How do I do this too? Any idea how much weight this saves? Thanks all.

 

dremel

 

... and a small grinder. If you want it bad enough, you'll find a way.

 

Any idea if the hood would actually bend at high speeds??

 

sure does... wobbles horribly.
make sure to get pins.

 

angled die grinder.

I love air tools.
