2014 Mustang GT
Installed BMR spherical adjustable Lower Control Arms. Did not install the relocation kits, is this a must? Installed 255/35/20 Firestone Indy 500 all the way around and there is a noise that sounds like something is rubbing. Accelerator related, when idling there is no noise or when i give it gas in when in park. When coming to a stop it goes away at about 5 MPH. The car runs fine no power loss. Can this be the driveshaft after installing the Lower control arms.
