Suggested tire pressure with x74 Suspension?

For street use, same as factory recommendation. IIRC, they are: 36 psi front, 44 psi rear, measured on "cold" tires. Changing suspension doesn't drive a change in tire pressures.

Setting tire pressures for track use is an entirely different exercise, about which there are plenty of threads and even more opinions. I have not tracked my car so cannot offer any useful advice.

In Miami? I never use factory numbers. The roads here are horrible. Even before switching to coilovers I run front at 32 and rear at 38.

Did you install RS motor mounts also? If so, the expansion joints on I95 and elsewhere are going to be abrupt at factory settings.

I run stock settings with the RS mounts. Geebus what kind of a nut tracks a car?

Try the it at factory setting and see if the rear dances around mid corner bumps. Although I have gt3 setup, there was no way I could drive at stock pressures. Currently happy at 34f/37r on v12s for street with my custom alignment settings.

I found stock 36/44 was way to harsh as someone said so I have been running 36/38 I guess I will start there and maybe drop fronts a bit as well.

Look carefully. I think those pressures are for a full loaded car.
