the 2015 kits will be out in about 4 weeks. I'll be one of the first to get it. As far as weight goes, it will weigh less than the stock suspension. Also, the air lift kits are made for performance. They are track tested and proven to be as good as if not better than a coilover setup. People...
Got mine installed today as well. This thing is a beast and shifts sooo good. That rubber boot gave us fits. Took a good 20min and some sore fingers. Everything else was simple. I also used a lift.
