4th gen setup questions. . . don't be stingy!

[Pranav]

Reading through this thread and others, I feel like I may be doing a number of things wrong:

Tire pressures: running mid-high 20s starting. This too low?

Spring rates: Went up to 750F/250R from 600F/200R last summer, no spacers in the back. Car feels stable and doesnt seem to push, but I think it's harder to drive offline now. Running 32F/19R bars.

Front camber: I know it's too high, can't get an accurate reading but suspect it is above 2.6*

My pyrometer readings are showing a 20-25*F delta between the inside (hotter) and outside (cooler) of the front tires, so I will take the car to an alignment shop and back off the camber accurately.

What should I aim for front camber/caster/toe when it's on the rack? -2.2 camber, max caster, 0 toe?

What should my starting pressures be?

Hoping to get to TWS this Friday to try out other variables (rear spring rate, rear spacers, tire pressures).
