[SRT Engineers]

Regarding the rear "rattle" noise when cold out of the rear. It is very difficult to diagnose these things without driving the car. That said, it sounds like a shock noise if it goes away as things warm up. It doesn't mean there is something wrong with the shock, necessarily. Some are a little noisier than others. Some cars are more sensitive to shock noise than others. We fight shock noise on SRTs because, like brakes, good shocks tend to be noisier than regular, wimpy shocks.
