Judging from materials used. Cheaper kicks ASS!! I'd say it's an investment well spent. Protect them hard to find/PIA to replace parts!
Looks like it's tig welded up good, 5mm thick, plenty thick. Aluminum is lightweight. I believe air craft grade also has to pass some NDT test for it to be graded air craft grade :-p
Aircraft grade aluminum is ridiculously plentiful around my parts.
I just wanna go fast. If your not first, your last!!
