Alright, everything started pretty much when I took my car to the dragstrip for the first time, that noise is coming from the rear left tire, everytime I step on the gas hard, and it goes away when I take my foot off the pedal, and sometimes it does it too when you kick the tire, you can hear like if something is loose or even broken. What could it be? how expensive is that part(s)? And how easy would it be for a do-it-yourselfer with not a lot of experience to acomplish that job?
Thanks a lot everybody, and dont forget to wave
