i just got some 22's put in last weekend. very happy with them
i got some nitto 420s along with them
they seem to stick pretty good. but i get a lot of vibration on the freeway

going at 70-75 theres no problem
but if i go a little slower around 60then theres
a lot of vibration.
i took it to the shop
i got a tie rod swapped. they said that was all the problem
but the vibration is still there.

any suggestions?

i thought i had warped back rotors. now i'm not sure

You need to get a road force balance done.

yeah go back and have them re balance them. i don't know what a road balance is, but it sounds good.

if you want something done right... i guess i'll get the machine at the shop and do it myself.

A road force balance is when they balance the wheel and tire with stimulated pressure on the wheel and it spins to 65-70 MPH, like it's riding on the road. Also tell them to use stick on weights on the inside and out side of the rim, outside but it will not be seen from out side of the wheel.

Did you guys make sure the little star washers holding the rotors on were removed. They can cause vibration problems. They are on the wheel studs, usually two on each rotor.

Oh yea check that first befor you have then re-balanced. To remove them, remove the wheel take a flat head screwdrivew and pry it off the face of the rotor then take pliers and pull it off of the stud.
