I have a 2000 Mustang with the Bump Steer Tie Rod kit installed and the massive sway bars. I'm looking at the next step and my local dealers deal in QA1. My first question is, what is the real difference between their race and street front lower control arms other than maybe bushings and the construction of the balljoint?

My second question is in regards to the rear lower control arms on the car. Currently it has the ford motorsports polyurethane control arms and bushings. In my Fox body days, i had Lakewood Traction Action Lift Arms installed in my 86 notch that seemed absolutely amazing. Instead of the back end dropping it seemed to lift the back end under load which supposedly multiplied the downward force on the rear tires. I heard people say they were known to cause damage to some cars and can be hard to get it seems now. Are these still really good control arms for a new edge? Is there something that did the same thing in a different brand people like better?
