The back are higher because it has less drag so less surface on the ground which reduces 1/4 time.

good try but not actually relevant - the higher PSI is to keep the rear (non driven) tyres firm and keep the load towards the driven wheels. IE in a FWD the idea is to keep the rear stiffer than the front
