I know on the older GMT400 and GMT800 trucks that the residual valve lived inside the master cylinder and that they used different valves for drum rear vs disc. I wonder if the Camaros have it inside the master or inside the now non-existent ABS pump?

I installed one in my car back in the day. Didn't make any difference.

So for what it's worth, the tighter used stock hubs combined with new Dorman c clips and rosette welded axle shafts made a huge difference in braking performance. I still have knowingly spread C5 calipers and need a left foot poke after a sweeper, but braking is dramatically improved from last season and a great deal of confidence has been restored to the car. Got Pranav's axle clips today and can't wait to try them out! I measured them at .167" vs .159 on the Dormans.
