I daily drive my mustang, but like most other people, i wanted more out of my car, so i ordered these lower control arms. Really great product right out of the box that they shipped in. The install took about 30 minutes for both of them. The hardest part about the install was getting the bolts towards the front of the car out since you can't fit an impact under there, and an air ratchet is too weak. However, once these things are done, installing the new control arms is very easy. I used ramps for the install and they worked just fine. The thing i immediately noticed after installing is that the car is definitely more responsive when accelerating from a stop. I haven't done any hard launches yet due to wanting to have a break-in period, but there is a noticeable difference in how the car behaves. Overall, i definitely recommend this product!
