well there is your problem!
Lower Control Arms and Upper Control Arms.
The stock ones from ford are kinda mushy and give easy allowing the back wheels to break loose.
BMR would be my recommendation. If your not lowered realistically you could just get the LCA and you would notice better traction. If you are lowered you would need a mount for the LCA to realign it to the axle.
Basically. The axle pushes against the LCA and UCA and they push against the car. If they are mushy and give in they allow the wheels to give way and break free. By doing stiffer poly bushings you'll get better traction.
The tires will help, but this is important too.
