If you sell your subframe and do a aftermarket subframe, I would run a Speedtech subframe with the Air Ride option. We can do it for under $6k to the door, and you get everything you want and more. As for the DSE frame, it WILL NOT run Air Ride, so it is out. morrison is very nice , we sell it to, you will spend another grand on it.
For the rear, Our upgrade G bar (Prodigy Bar) is pretty nice and easy to install. but we sell the Quadra Link also, so at the end of the day i do not care which you buy from us.
Here is some Prodigy bar info
