One of the things I'd like to get rid of on the FB are the weak control arms. As an avid car enthusiast (not just rotaries, not just RX-7s) I constantly check out things like Street Rodder, Hot Rod, etc.
A lot of companies offer Mustang II suspension upgrades for early 30s street rods, and the control arms look custom fabricated.
Is there any reason why we can't make something like those for our cars? As long as the mounting points and geometry are unchanged, can we create a stronger part?
