I know your responding to what was said but if you just want to compare a coil over kit like myself or hdk sell the pricing would be nearly the same for the front end parts. Your also quoting the most expensive kit on the market. The GTS or HDK are much cheaper than the alter k. I sell my kit for guys that want the torsion bars out of the way or for drag racers, I'm not here to say which is better or worse. Like everything, there's pros and cons of each.
