trying to figure out what is causing the vibration. the car is awd and lowered on road magnet springs. car has been lowered for 1yr (no issues) and the aligment was done last OCT. I just installed some 19" linea dynas along with the hud rings and the is a very noticable vibration at about 60 mph.

tire specs are

235 35 19 front
265 30 19 rears

does the car need to be re-aligned? should I take the hub ring off... HELP

 

Are the wheels balanced?

 

Id have the wheels rebalanced and I guess try running without the hub rings. Although you would get a vibration if you didnt have the hub rings installed. Also are your tire sizes correct for a staggered set up on AWD? Sorry, i dont know the math. I also dont think you need an alignment after installing wheels.

 

wheels are used but appears to be balance as I am not getting the usual steering wheel shaking left and right; just vibration.

tires are fine for AWD

 

Are the tires cupped or feathered?

 

I had the same issue with snow tires and wheels. It is the hub centric giving you the vibration after 60mph. I did the re-balance but didn't help. Found out that Hub centric rings were not exact fit on the wheels. Replaced to diffrent hub centric rings and vibrations are gone. but still have little vibration.
Also, Re-alignment helps too.

 

Wheels have about 5k miles on them. Tires are about 95%. these should be the correct hub ring. U think if i remove them it would help

 

has your car sagged from the year of drop?

i had a similar problem like yours, it was due to being way to low i had a 06 m45, sport package and decided to lower it on eibach springs which was the same height so i chopped a full coil off and had some 19's put on with 35 series on the front and 30 in the rear.. eveyrtime i switched to stock wheels it went away.. so it could be one of the 2 hub ring or just being to low, by the way my over all drop on the car was almost 4 inches from the sport package, basicly a tennis ball couldnt roll under my car
