My Ride: 2008 535i Premium, Sports, Comfort Access
Usually I just go by the sticker in the door jam, which states 32 in front and 35 in rear for under 100 mph. And 100+ states 38 Front and 42 Rear.
I might break 100 on a longer trip if I'm alone but dont plan on doing it day to day, but i went slightly over recommended and put 33 Front and 37 Rear. Curious as to what others are doing. Thanks.
I have sports package with the regular wheels they put on it(think 124's)

I'd go to the 38/42 settings ... though splitting the difference 34/38 is pretty OK too. The lower pressures (32/35) soften the ride a bit ...but only just a bit for RFTs.

You can run anything between the maximum and minimum pressures. I start with what's on the door placard and add on some extra psi since I prefer a firm ride. Then tweak a pound or two till I sense perfection.

40 all around to make it simple...
40 all around for 19s? Does that include the Pot Hole and the "Get out of the way Dumb Curb" too?
I bet the 32 PSI at fronts suggested is to protect just that... Bent rims, suspension, and yes add to racing desired gripage...
