This is my second experience with Dynamic. I am slowly reconverting a 2007 Mustang from race ready to performance street, and some of the more difficult tasks have been covered by Dynamic when I'm unable to do my own work in the family garage. This round, the upper and lower control arms needed replacement to soften the ride and complement a new suspension that was recently installed. In doing so, they were not only able to demonstrate the previously installed parts were failing, a nagging "clunking" sound was diagnosed as a bad aftermarket drive shaft, which I will purchase and have installed by the Dynamic team. Soon, I will have a pleasant low mileage daily driver. Regardless, the new controls arms have made a huge contribution to a smooth ride with exceptional handling on corners. Thanks again Dynamic!
