Well well, you cant always take someopnes word for what they tell you. The shake was my wheels/tires. Today I rotated them around and checked the air pressure, the tires ranged from 30-35 psi. So I put 33psi in all of em and went for a ride. Now the car does not shake at all at 45, and you can only feel it in the stering wheel at 55 slightly. So at least this is solved. time to sell these wheels/tires and look for some quality ones. My cousin has a $4,000 set of wheels/tires he's getting rid of for $1000. awesome deal, I'll see if they fit.
