have a 2011 roush stage 2 with the upgraded brakes and suspension options . getting some bad noise from suspension when first start driving . have heard it a few times in warm weather mainly after it has set for a while , but very noticeable in the cold . I know the abs can make some noise as it adjusts when first start rolling but this sounds pretty bad . after applying brake a few times it stops . has anyone else had this problem ? also have heard some noise from rear when I hit small bumps is this normal for the roush upgrade ?
