Nice job you've done there Genius.
However, a word of caution :-
- removed part of the splash guard to save weight
(You can't save much weight removing a small piece of plastic here. On the contrary, you might compromise it's effectiveness)
- grinded the chassis braces to save weight
(Taking away more material would weaken it's structure, as the manufacturer had already used as little as they could to cut cost)
- milled different areas of the chassis to save weight
(Overworking here put off it's balance, as well as allow too much flexing)
