No, well... to be honest, only after I got the Hotchkis adjustable shocks on the front, I started keeping an eye out for a better rear shock than the Monroe Sensatrac's I had at the time.
I happened to stumble on the pair of Bilstein's for a great deal, and fairly soon after these I spotted these single adj. QA1's for sale locally for a good price.

The QA1's have more compression friction than the Bilsteins which limit the downward motion of the car's rear end.
I've also noticed the car/rear end stays flatter in the corners, which was still a bit of an issue with the heavy propane tanks I've got in the trunk.
