Pretty certain the rears of a 911 like that is closer to 42 when cold. 50 is still a bit too much unless this is after warmup in which case maybe 6-7 pounds too much.  Rears are almost 10 lbs more than front for street driving. 

The door jamb cold pressures for my 992 GT3  are 32 front and 35 rear, but Manthey said the performance setting (for road) is 29 psi front and 32 psi rear cold.  May be different for a C2S (check the door jamb and maybe lower a bit from there)...

If Cup tire then the 29/32 is what we all run  for the road. If track a bit lower.  If tire are 4S, pressure will be higher around 33/36
