Not for sure if they left the actual mounting lug location/distance/offset the same, and am thinking they ARE different, but they certainly have made some nice improvements to the Upright "Steering Knuckle" to help combat deflection that occurs in the current C5/6 Upright. Although all these front suspension/steering components look similar to the C5/6,,,, they are different and will not interchange.
Oh, and the lower arms are now hollow I believe for a considerable weight savings too....
Wondering how long until DSE, RS, AM are designing around these
