Vibration after 120mph?
Long story short, if I go thru the gears on the highway, I get a vibration that you can feel in your feet, once you get past 120mph...

Where should I start? Lol

I understand that it's not normal though, car never did it... You can feel something like wobble, and you feel it in your feet..

0possibly could be my tires. But the wing is a low rise, and the feeling I feel is like a wobble in my feet, would do it at the drag strip also where I don't go over 110.. Could be a bashing possibly?

Or brakes possibly?

You weren't the one that says he does 160+. Could be a bushing. Could be a wheel bearing. Or a router out of round. Though I'd suspect those last two you would feel more in your hands than your feet.

Start by balancing your tires. Proceed to checking the ENTIRE front suspension, brakes, etc etc.


Basically DON'T GO THAT FAST ON A PUBLIC ROAD YOU IDIIOT!

Just so you know the stick on weights that most shops use now for balancing don't hold on very well at high speeds. You go for a burn up the highway and they fall off and you will have a bad balance/vibration again.
