Driveshaft Issues

On my 2012 Roush I took it to the track and the small bushing on top of my rear end got shredded. At this point my driveshaft hit my floor pan and has scratches on both ends. I replaced the bushing with BMR, put in a new transmission mount, put new bushings in my BMR upper control arm, checked my motor mounts ( they're fine) and noticed slack in my lower control arms so I'm about to replace them as well. My driveshaft still rubs but only under hard acceleration and also if I hit a significant bump. Any ideas on what the problem could be? (The driveshaft has been installed for over two years with no issues. Dynotech 3.5 Aluminum)

If your driveshaft is rubbing then you probably have pinion angle issues, I would assume....

Yes BMR told me the pinion angle needs to be -1 to -2 degrees and it is but under acceleration it still rubs. I have yet to install the LCA bushings but do you think they could be the cause?
