I have one on my 2015 Scat; it's from Per4Mance Development. Very well designed and crafted; even the install instructions are well thought out.Do you guys use a differential brace on the race car? What got me interested is a member had one listed in parts for sale in by Per4mance Development. I have not seen this part before for Challenger application.
That's normal as the torque of rotating the axles (half shafts) is resisted. The diffs have rubber bushings to keep NVH levels down.In the vid it looks like the diff. is moving forward and backward as you drive, is that right?
