Suicide doors has changed their name and is now Quality Air Ride and they sell the universal strut kits and air management kits, but nothing that is a direct bolt on application for these cars. The "good" universal strut kits runs the geeks off the streets around $885/pair, but that's just the struts. You still need air management. Things like compressors, valves, tank(s), switches, line, gauges, and fittings can be a hefty bill depending on what you choose. $3000 is a pretty easy number to hit for just parts.
blu_fuz for the most part hit the nail on the head when he said the cost to practicality ratio is what stops most people. Just be aware there is a massive amount of misconception that surrounds the topic of air ride. This mostly stems from people not picking a direction, trying to build it to meet any and all directions, and expecting to build it with all the advantages and none of the disadvantages.
Example:
I'm going to build a weight reduced demolition derby car that doubles as a circle track race car and triples as a 9 sec drag car with the ability to win first place at the weekend car shows and maybe drift it from time to time if the need arises.
You get me? :laugh:
Weight addition and ride quality/performance probably are the most common misconceptions. People will talk as if you're adding 800lbs to your vehicle, but the choice in parts and how you mount them is a hugely definitive factor. I could maybe see 30lbs in additional weight on an SVT over stock if you go mildly heavy with parts and install. Obviously, if you over build everything and use .25" plate to mount anything and everything, then yeah, you're adding excessive weight. Although, in the event of building it that way, the likelihood that you're building a project car like Pole120 is very slim.
I don't believe performance is at a disadvantage either. I think it's use in a performance arena is so slim to none that the potentional hasn't been recognized yet and it gets the short end of the stick and poo poo talk is the result. Much like the view that used to surround snowboarding in the early 90's.
With companies like AccuAir developing pre-set ride controllers, accurate to within +/- 5 psi with the touch of a button imagine the possibilities!!
Picture a track car like Pole120's building with onboard air ride control accurate to within 5 psi just by pushing a button. Most the track cars that I've seen like that have a passenger, so you give them the controller. Lets say they find that on certain right turns they can shed some time by altering the pre-set ride height by adding 30psi to the left side of the car and dumping 15psi on the right. Set it as a pre-set. Same for the opposite side, only lets say that Pole's passenger weighs 30lbs more than him and so to compensate 50psi to the left side and maybe 10psi dump. Pre-set again.
So in 3 button pre-sets you have left and right banks covered and the standard ride height to level the car out for the straights.
Tell me that doesn't sound badass or that it's a disadvantage to have on the fly adjustabilities!
I just say it hasn't had enough exposure.
