No, the front upright change was for two reasons, number 1 was caliper knock back due to spindle flex. The bearings in an original Cobra were tiny to package inside the threaded hub. I went to a Kirkham style cartridge bearing like newer Corvettes use. This eliminates any flex in the system and resultant piston knockback. The new lower arm was required because the hub carrier would not package with my steel fabricated arm. The mounts are common to what I had before so load capability is the same. The second reason is that the cartridge bearing has a through bolt that is perfect for mounting a 48 tooth tone wheel on and it rotates with the hub. The original spindle would be a bear to mount a tone wheel and sensor, this was easy.
When I first saw the new hub carriers I thought ABS because they are perfect for it. At the rear I sandwiched the tone wheel between the drive shaft and drive hub and used the unused caliper mounts (hubs are common LH and RH and have ears on both front and rear) to hold my sensor bracket. Had to buy Witworth allen head bolts but it worked. These sensors have to be very solidly mounted because any vibration could send false signals to the ABS computer.
