I have a 05 plate blobeye PPP, im getting a metallic rattle from under the rear of the car. its not the shockers as they have been changed for coilovers, im wondering if it could be the anti roll bar/droplinks rattling in some way or could it be the baffles in the back box that have come loose, anyone else got this problem or anyone got any ideas ???

its quite loud when i drive over dumps and things and its sounds like a thin metal rattling if you know what i mean.

Any info would be great.
