>>>I have the same shocks. Mine is 4.5 at the front and 5.0 at the back, a
full inch lower than yours. Of course, tire height affects that as well.
I have 245/50 front and 305/50 rear which are rather tall compared to the
tires often seen on 17-inch wheels, so if I was running those, my car would
likely be lower still. It's not 'slammed' like a ricer car though; I still
have full suspension travel and compliance.
My rear A-arms are just slightly higher on the inboard side (that is, they
are close to being flat and parallel to the ground, just a tidge lower on
the outboard side and higher on the inboard side). That is pretty much
optimum. Those who lower their cars excessively affect the camber curve in a
negative way; as soon as the suspension compresses further, the top of the
wheel tips inwards and you get excessive negative camber.
Regardless of what you choose to do, if you alter your ride height in any
way you will need to align your wheels.
Cheers!

I measure 5.5" inches at the front Drivers from the bottom of the
rocker panel
spot weld seam to the ground and 6" Drivers at the back from the
bottom of rocker panel spot weld seam to
the ground. I measure 6" inches at the front Passenger from the
bottom of the rocker panel
spot weld seam to the ground and 7" Passenger at the back from the
bottom of the rocker panel spot weld seam to
the ground. This is with a full tank of gas.

I have Dennis Quella's Koni' shock/spring combination on the
car, so adjusting the ride height is not too big of a deal, although
it may require another alignment..
