is it possible you dented a rim? Ive run 140+ fine and I'm droped pretty good on coilovers with a fairly low offset all around of +10 and stretched tires (235/35 and 255/35 on 19x10 and 19x11)with no handling issues

 

Not that I know of. The integrity of the rims seems fine.

 

Wheel bearing! Check your rears for play. I had similar problems with my Z and it turned out that the driver side rear wheel bearing was toast and the axle nut was hand loose
p.s I only had 11,000 miles on my car when the wheel bearing failed and supposedly its a common issue with the Z

 

Somebody been watching The Fast and the Furious too much?


You might want to take your car to another alignment shop. If they're saying your caster is too high in the rear, they're off base and may not be the most knowledgeable in the world. I say that because caster only applies to wheels that steer. And unless you've done some SERIOUS mods, your rear wheels don't steer. Maybe I'm wrong, but based on things you've said, it sounds like you didn't do anything to get more adjustablity for alignment settings (Nissan did not give us much at all from the factory). You might want to read Jason's excellent primer on what you need in order to get your alignment back to good after dropping the car:

Suspension 101

I'm absolutely no suspension expert, but I'd guess that a number of people on here are right...your problem stems from crazy offsets (no idea why you would want your wheel sticking out from the car like that, but to each his own), stretched tires (again, to each his own?), and fried alignment. After all, since your wheels are sticking out so far, any alignment issues will be magnified.

Someone suggested removing your spacers and seeing if the issue got better. Did you? I wouldn't expect the problem to go away, but I'd bet it gets better.


Oh, and in your initial pictures, it looks like your rear fenders aren't rolled?? How are you not rubbing like mad??
