Took the car to goodyear this morning and they put all 4 tires on the road force balance machine. All of them were pulled from lower 30's to under 20 lbs (max acceptable). Drove out of the place hoping that the matching would fix the issue but it did not.

Now all 4 tires matched to rims and fully balanced and still have the vibration only while coasting. I have a pair of front control arms on order but I am getting married this weekend so it will be a while before I get those installed.

@jst2878 - Swing arms look good and there is no noise. Need to check the hub's. I should have done that while the car was up at the goodyear place this morning.

It seems the issue only occurs in a free rolling state. When under power or braking the issue does not occur. It also got worse as the fuel level got lower (probably because of less weight).
