Hotchkis Total System

Looking to see if anybody has ever used the Hotchkis Total Vehicle Suspension System. I have a 70 Dart 360, about 325HP, stock set up mostly.
727 Tranny 8 3/4 355 rearend. A suspension upgrade is my next step. Plan to use Performance Suspension Technology polygraphite front end kit and replace anything near needing it. Have no sway bar on front or rear currently so need both. I use this car for cruising, no drag racing, but they have a real nice road track opening near me so some time on track would be fun. I like the stock height and appearance. Does anyone have experience with Hotchkis or another way to do this upgrade? Heard a lot of good about both PST and Hotchkis but never using this complete kit. Money not a huge factor but want my dollars worth, mostly looking for good handling on the street. Most of you know a stock 70 Dart is not much on handling the road.
