Getting an odd squeaking / squealing sound coming from rear of my new Roush Slingshot. Already brought it in for the 500 mile service and they said they didn't see or hear anything. I hear it every time I drive when slowing down and speeding (at lower speeds). The suspension does not squeak if I push it down in the back so I don't think it's that. Possibly the brake / emergency brake rubbing or needing adjustment? I can feel it slightly in the chassis too. Any help would be greatly appreciated. I don't want to drive an hour and a half to my dealer if I don't have to.
Here is the sound. Starts around 6 seconds and again around 11 seconds
