I'm running complete Firm Feel system in the Road Runner. I'm planning on stepping up to a larger sway bar install this winter. The only thing I didn't do was I chose not to box the lower control arm. I wanted to go with Hotchkis but at SEMA several years ago I stopped by their booth and they wouldn't give me the time of day and they didn't sell a total system for my 71. If Hotchkis sells the A body parts as a total system it's well worth the price. I went with Firm Feel because Hotchkis didn't have a total system for the 3rd gen B Body, I didn't care for their customer service and I decidee to buy from a NW dealer who I've had some history with. Dick did cut me a smokin deal on the shipping.
