The ride is one reason you want the cheapest shock you can find, light
truck compared to a Crown Vic, or even a Mustang, never tried those
shocks, could be a better match, I'll take one of mine off and go size
it up to a Mustang Shock at the Autoparts store
Air Pressure, most people use the rated max pressure on the tire, WRONG,
you should always use the listed pressure from the vehicle, and bigger tires
make the pressure needed lower, like the difference between a Bicycle tire
and an ATV, bike 45 psi ATV 3 psi, SideKick 23 Factory, bigger tires like 235s
I would go to 15 psi for ride, if you want MPG leave it higher.
Eric says mark your tread with chalk, then drive around the block to see where
the contact patch is, keep lowering pressure until the chalk wears off evenly
across the whole tread surface, this is the best pressure for that tire and tread life
