I Thought I ordered some arms along with my car and other parts, 5min into running it I hit my trash can n BooM! I seen the arm hanging from a distance! Ahhh make sure u order all front end spare parts to be safe, and if u have extra cash to spend ,up grade the shocks, Awesome fast car! Zippy Fun!
They are available in aluminium, look for SKU: A2003-30911
But I would not reccommend replacing them because then something else would break instead. These lower suspension arms are the easiest piece to replace! I bought ten of them and so far have 8 pairs left...
Instead I bought aluminium servosaver set and steering knuckles and left suspension arms plastic.
For future knowledge... the part you mentioned SKU: A2003-30911 will not work for the 1/16 short corse truck. I just purchased several of them. It is way to big (not even close). It would be wonderful, Turgnigy, to have an aluminum replacement for these though.
