Hi fellas, how can some ( like mine and bad boy rs) knock and vibrate and others not even be close?!

I am running a STD arb for gods sake!!

Answer this, would you at any point machine the mounting lugs on the rear cover to get these things to fit? Or is that absolutely barking?

Please be brutally honest, I just want to get in this thing and enjoy the drive! Not asking too much is it?!

Thanks for your comments fellas
