vibration at speed....lowering the cause?

Over the years, I've seen some chatter about driveline vibrations from lowering being the culprit. Any substance to this?

We have H&R springs, KYB struts (new this year) all around. Had 20" OZ Michelangelo II with 265/50 Avon Tech ST. Just put 20" Rays R.E.M. Masterpiece with Hankook Ventus ST (same size). Still have the vibration, around 60-70mph. New brake rotors and pads in Feb too so that's out.

Suggestions?
 
I believe there have been quite a few posts related to this topic. I have posted this topic a while ago and i was told it is normal vibration. My wheels are perfectly balance and I still get some minor vibration on the freeway.

Dr2k mention something about tires being wider and more surface area that the tires will feel leading to more feel on the steering wheel. Not a satisfactory explanation, but I believe this is pretty common on all of us.

I think it's perfectly normal.
 
I read through many of those threads and there were any number of issues at play. Sometimes adjustment in the steering rack, sometimes a fifth wheel balancing was the ticket. Just wondering how much effort/money to expend sorting it when it's a symptom of being lowered.
 
Didn't read through the thread but going to chime in anyways since I'm probably the only person experiencing vibration for a loong time (2+ years). I've tried everything and anything but the best solution was to use some teflon tape to make sure the wheel is perfectly centered around the hub.. Tightening the steering rack helped as well but it also pushes the vibration to higher speeds and the steering gets considerably tighter..

Excuses in advance if this has been said or is irrelevant.. I just don't have enough energy to read through now..
 
teflon tape can't hurt but given 60 degree taper lugs, it's probably not the issue (even though there are hub rings are installed).

I used the tape for hub centering purpose only.. It doesn't do anything after you tighten down everything.. The gap was so small between the hub and the centering ring that regular electrical tape didn't fit.. But even with that tiny movement, it was causing vibration at higher speeds..
 
Its either the mount and balance, or the rotors. The only thing, if it vibrates, and your not breaking. Then its def the mount and balance. maybe a weight came off while you where driving.

i agree with mongolian. I've had this vibration ever since i switched to wider 20" tires from the stock 18s. Ive tried alignment, bought it to a couple shops, and they did what they could do. However the steering wheel still vibrates a little at high speeds and sometimes low speeds (depending on the road)

now with my moms minivan, which is in desperate need of an alignment, there is no vibration in the steering wheel. I think it might have to do with how the steering is so light.

anyways good luck, and keep us updated if you finally find a solution!
 
Regardless, ive seen a lot of funny thing cause shaking, or a shimmy, and it turns out to be something small. Just adding factory 20 isnt enough cause that kind of problem. I would personally take each wheel off and remount them inspecting it myself. If you have a friend who has a lift, maybe he can let you run it on a lift for a better look.

I had a long term vibration between 40mph and 60mph after mounting my 22's so I tried the teflon tape around the hub lip and the OD of the Hubcentric wheel adapters till there was a very tight fit --This did the trick vibration 90 percent gone. I think a road force balance will take care of the rest.

Thanks for the tip Ege:tup:
