Chase & Jeff - In case it's not said often enough, the 86 community appreciates the honest and thorough answers that you guys take the time to provide.
It only takes 1 person to say that "6061 is a decorative material" and the myth gets perpetuated.
Coated steel is cost effective and works for most environments. Grimmspeed's focus has been functionality (with an approachable price tag), so it's easy to see why they went in this direction.
For aluminum, here are the main choices (disregarding cast alloys):
2024 for high strength, medium corrosion resistance
6061 for medium strength, high corrosion resistance,
7075 for high strength, high corrosion resistance
If you aren't welding it and cost is irrelevant... 7075 is excellent. 6061 is half the cost and easier to work. 2024 is solid, but for exposed locations (like an engine bay) you'll want to coat it. For Perrin's goals (gorgeous but functional parts) 6061 was a great choice.
Pick the one that's best for your budget, location, and purpose. The design of both parts gets the job done.
