Rear suspension recommendations.....

I have the Frimfeel setup front with 1.0 Tbars and new back springs with their sway bars on my 72 Duster. Without the sway bars it was a nice softer ride that would be great for daily driving, but once the sway bars went on, the car now feels super planted and carves the corners really well and setup more for autoX and really spirited driving. Frimfeel used to road race mopars back in the day and if you look at the old AAR/TA Cars they used upgraded stock style parts and ran very well. I've seen a few of them (AAR/TA) running at Sonoma and still not running the the QA1 conversion.
