Not sure of today's choices, but back when Alter K was the only streetable setup available I bought one for the Dart. Dropped 150 lbs off the front, and it drives like a new car. The cost wasn't bad considering how much i would have spent rebuilding/replacing the worn out suspension and steering box. I wanted the torsion bars to be gone anyway. Never had any problems with customer service...in fact, when Bill modified his design and narrowed the track width of the Alter-K, he shipped me the revised A-arms and new bushing as well, free of charge. The one i have is an early type with a crossmember made of welded square tubing. The mandrel bent type crossmember might have an issue with water trapping in the cup formed from bending...not that many will see any rain.
