Re: Rotors and Warping

Yeah... one of the HUGE things missed is that we have seen in repeated experience that unevenly torqued lugs cause 90% of the "warped" rotors. I've seen it over and over on my own car and others!
BINGO!! I couldn't agree more, and I too have seen it over and over.

keep your wheels torqued evenly and I kid you not the difference in time that the rotors last before feeling warped is significant. I personally run cheap rotors even on the race car and have never cracked or warped a rotor yet.
Did I say that he's 100% right? Well, he is! :P
Just because a tire shop installed your wheels and said that "Yea, they're torqued correctly", don't believe them.
My neighbor got some 23's for his Titan, installed by America's Tire. We were looking at them and he said that on the way home "His steering wheel shook a little" and it didn't do it before the new wheels, so I mentioned proper lug torque. That led to me checking his lugs, and on every wheel, one lug was over 120ftlb's, and the other lugs ranged between 75-100ftlb's. :shock:
I loosened all the lugs, then I torqued them to Nissan's spec in a criss-cross pattern, and his steering wheel shake is completely gone. Oh yea, I sure enjoyed the tacos and Corona that he bought me for fixing his problem. :P
BTW, he bought his own torque wrench, and he brings it with him when he gets his tires rotated, and he makes them use it while he watches.
