Okay, I get the idea that this is a performance machine, but that doesn't need to mean that the parts are short-lived. I've been the only owner of my 2006 MazdaSpeed, and besides an occasional run into the triple digits there's been no excitement in the cars life. I don't abuse the brakes, and in fact most of the time I try to take it easy on them, slowing down well before corners, lights, etc. So I start to get this left front wheel wobble after I put my summer wheels on, take it to my tire place and run it through the balance machine X 2 because the first time wasn't the cure. Still there a bit after the second so I take it to the dealer because I'd just had the left front bearing replaced under warranty not too long before and I thought that might be the problem. I'm told that the rotor is badly warped and needs replacing (can't turn it because it's ventilated and there's not enough metal there) and so is the right(eyeballs)(eyeballs)(eyeballs) front. In addition, both rears are on their way, too. My question: the car only has 40,000 miles on it, and why the heck should all 4 rotors need replacing at this low mileage????? Anybody else had this problem?
