The RC Racer TRF421X Front Stiffener 3D Print Files

Well known Tamiya website The RC Racer has released files for the 3D printing of a Front Stiffener for the iconic Japanese manufacturer’s TRF421X 1:10 Electric Touring Car.  Now common options in modern touring car, the Front stiffener helps with preventing the bonnet flexing on lightweight body shells.  Run by Craig Howard, The RC Racer has created two versions – Soft or Solid.  This Soft allows a little more flex at the front of the bulkhead. It makes the front end more stable into the corner.  The Solid version is if you want to keep more initial bite into the corner.
