R1- The new "R" shocks come with a hardened coating in them, and thus far seem to be holding up really well, and not all the "blackened oil" as with the old version. As for the front arms, both the top and bottom arms work out to be the same, "as far as position and angles" as the old arms, it's just that the new arms are made a little different. Such as the tops having the steep arch in the rear to clear the ackerman arm while turning in air at full droop. And the bottom arms are thicker and better braced, and notched out more on the bottom to allow for all of the down travel the new kit has.
As for front uprights, they appear the same, with maybe a little thicker bracing leading out to the steering links.
