For those of you who race Getrag 226-equipped Challengers, there is a new product, from Per4Mance Development, that strengthens the differential, improves traction and lessens wheel hop. It is a two-piece differential integration and reinforcement system. Part one attaches the differential using the lower two main case bolts and the three lower case bolts to reinforce the differential. Part two attaches to the rear cross-member and carries an OEM differential bushing (just like the two in the rear cross-member) to add a third, triangulated integration point to "attach" to the reinforced differential.

Not sure whether recent model Challengers need an aftermarket brace. My car doesn't give me any indication that it needs one. On the other hand, my 2003 Cobra benefited greatly from one. The addition of one was transformative. Felt so more stable in corners and over any transitions that worked the rear suspension. If that degree of improvement would be seen on a Challenger, it would be well worth the money. Unfortunately, for my Cobra, it didn't have much effect on wheel-hop.
Wheel hop happens more with the manual trans cars than it does with autos. But a hopnot kit will take care of that. Sent from my iPad using Tapatalk
it HAS to be more controlled than without. When I drop the clutch with slicks on, it's like old WashBoard roads in a 1-ton truck
I agree, was just commenting on the video evidence. To me, the differential seemed to move MORE in the "after" video. Seemed very curious to me. Not familiar with the differential in these cars but back in the old days, we put braces on the FRONT of the differential because there's simply more leverage putting a brace out front by the nose near the pinion bearing.
