Alterkation or HemiDenny

I want air ride on my setup to, so i can raise and lower it. HOWEVER. just heard back from Bill at RMS and he points out his opinion and experience with it...has me thinking twice now.

" On Air Ride, we discontinued the option in 2008 due to it being terribly unreliable. The ride quality is impossible in heavier cars, kind of reasonable in A-bodies, but in the end it's for trailer queens really. Anything that will see driving time needs coil-overs - they're nice riding and handling, and bullet proof for years and years. If a show car is what you're after, I can include parts to allow Air ride on request, but I highly recommend sticking with coils. Not to mention the added cost of air can get out of hand in a hurry. "
