We have a 94 Mustang which puts out around 500 HP. Used mostly as a cruiser, but is taken to the track once in a while. Been driving it for about 4 years with no problems other than wanted to put rust preventative on the lower side, inspect the torque boxes and replace the OEM arms which have 175K on them.
Does anyone have experience with the spherical bearings on both ends of the lower arm and running conventional upper arms (with rubber bushings) on the Mustangs without pan hard bars etc?
Read about Maximum Motor Sports products and talked to them since they are recommending spherical bearings about 400HP. They recommend the spherical bearings on both ends of the lower arms to provide less wheel hop. They also recommend a pan hard bar (to prevent side sway) and a torque bar (to prevent rotation of the housing) instead of the upper arms. This involves another $1000 investment.
I cannot afford to spend the extra money to buy the pan hard and torque bar so I would like to find out up front if anyone has experience using the spherical bearings on the lower with rubber bushing on the upper. If not I will go with Polyurethane on the lower and rubber on the upper..
The purpose of the call was to find out how side sway (body shifting left to right in relation to differential which can cause tires to rub) was controlled if you had spherical bearings on both ends of the lower arm. They pointed out the purpose of the upper arms being at an angle to each other is to control this. The conversation made a lot of sense. The ways the upper arms move with relation to each other puts stress on the system which is why you would not want a rigid bushing like polyurethane on them. When to rigid, binding of the suspension and excessive stress on the chassis occurs.
I read articles here saying not to run Polyurethane on both upper and lower due to possible binding which makes sense.
I also read the article below which implies a pan hard bar is needed with spherical bushings to prevent side sway. In this case they had spherical bushings on all arms.

Beat to death panhard bar question
On my car, I have J&M upper and lower control arms, J&M upper spherical axle bushings, ad the lower control arm has spherical bushings as well. But the body had the poly bushings. After reading about MM highly recommends using stock rubber bushings. I'm curious if my spherical equipment will...
