Hey everyone, just got a 85 gs rx-7. took the car to a buddy's shop, to get it on a lift & change oil, rotate tires, check fluids etc. Anyway, after all was said and done, i left on my way back home. Going about 40mph, and over the motor & music, i hear a clunk-clunk-clunk sound. So i pull in to a lot to check for anything that would be rubbing, and theres nothing. Keep driving, and notice it gets faster with the speed of the vehicle, as in wheel speed, not motor. And by the time i arrived back home (total trip of about 2 miles) it was way louder than it had been when i first noticed it. Any input would be greatly appreciated! Thanks, Landon
