I installed a diff brace and that increased the vibration even more so I have to take it off. To ensure the diff brace is causing the vibration so I installed it to my friends BRZ and he doesn't get the vibration 
I ended up put the stock one back on and the vibration went away ! I am not sure if it's me or my car or something to do with the shaft !
Does anyone has the same issue ? |
No I'm not noticing that the only reason I can tell its on my car any more is the slight honk when it unloads/loads up on power shifts.
