The brackets that came with the FWF kit are all steel, but won't work right with my superior cold air intake and my AFP fuel system. I fabbed up some aluminum brackets out of 0.125" 6061 angle initially as a model for the steel, but they seem pretty stocky. Anyone see an issue with using aluminum for this application? Thanks for your feedback.

The aluminum will be more susceptible to cracking, and this is an area where you don't want to have anything loose and shaking around. I'd suggest a steel bracket for this reason.

Aluminum for me

AFP supplies aluminum brackets for the mixture and throttle installation.
I fabricated additional parts out of aluminum (.125) to adapt to my installation.
My RV8 had 450 hours after 6 years of flying and no cracks on any parts,
Same for my RV-10.
Keep the brackets as short as possible and brace them if needed.
The engine is built of aluminum too and I don't mean to downplay the concern for a safe installation.

Back in the day........

when Van's didn't supply anything forward of the firewall, I fabbed all my brackets out of aluminum angle and sheet.
20 years later I have no cracks.
