How can I decrease the amount my Chevy HHR squats in the back when I load...

[Neil Hunwick]

...a powerchair on my external carrier. I installed a class 1 hitch onto my 2006 Chevy HHR (no problem), this is to allow my to load my son's power wheelchair onto a external carrier (with loading ramp). The hitch works great and is well within it's load rating. However, my vehicle squats about 4 inches when I load the chair. It weighs about 160 lbs total, the carrier weighs about 40 lbs.
Should I change springs, shocks, leaf springs? Not looking to completely eliminate the squat but would like to reduce it by 75%.

your best bet is go back to the 70's thing and get air shocks -they now have pc controlled levelers on them -expensine but work well-other wise do the air thing yourself
