On my door jamb, it reads for speeds up to and over 100 mph, recommended setup is 39psi front/45psi rear, a 6psi difference between front and rear.

I run a COBB tune, so the higher pressure in the back helps with grip, but I run 36psi front/42psi rear for a softer ride (hehehe) and in anticipation of temperatures increasing the inflation plus or minus 3psi front/rear.

I also have a Quaife diff, so I like to drift with the higher pressure.
