Tire pressure question

Okay! Now that we know what you want to do with your car.....
For autocross, I would start a couple pounds short of max, (51?), then maybe 48psi. Then play with pressures, depending
on over or under steer.
For drags, fronts at 51, rears, I would have to experiment, probably start around 25, and play around from there (run as much pressure as you can that will hook)
For street, your original first post number is fine.
Just my opinion....
