My Z always had some vibration coming through the steering wheel at around 75 mph. I bought it new with CCW wheels installed at the dealer.

After reading a few posts on those stupid rotor retaining nuts that the factory puts on, that because aftermarket wheels don't have the pockets to clear them, I decided to take them off.

There's two per wheel, after I was done, off to the highway I went and all is good again. That has to be one of the cheapest fixes ever.

So if anyone has aftermarket wheels and vibration issues, before you spend money on balancing, alignment, etc,. take those things of first.

It's not the weight of the nuts that's the problem, it's their location. They prevent the wheels from being flush with the rotor face.

I had the same problem also. Removing those retaining washers worked wonders.

i noticed it too. i have recently oinstalled pfadt coilovers and 360 forged wheels and nitto invo's.I had it on highway for the first time and around 65 to 75 i had steering wheel vibration, like my hand was trembling holding the wheel. i did have sensors put into the wheels after they were balanced and the car aligned. wasnt sure if that could have been the problem. and knew nothing of the rotor nuts until i searched the forum this afternoon.

the shop that did the alignment after the coilover and wheel install used the factory specs for the alignment.
