Hey pauly,
Glad I could help! As for Air Ride, Air Ride Technologies is one of the best set ups to use! When it comes to running Air Ride is to make double sure that everything is done right! Especially if you drive your PT, as you really do not want to pop a bag, or lose air pressure while you are cruising down the freeway at 70 MPH! Just be careful, and if you will have someone else install the kit, make sure you sit down, and talk to him, to make sure he is qualified, and able to do the job correctly! Make sure he uses good heavy duty lines, and fittings to help avoid leaks!
Now for the fun stuff! First off is a Youtube Vid from a company in the UK who does Air Ride. It is a great Demo on what it does and how it works!
And here is the official Website Listing. I don't know much about the Unit, or if you could even buy it anywhere, but it gives you a good idea anyway!
Air ride - air suspension for any car - supplied or fully installed » PT Cruiser
A complete Air Ride Kit can run you anywhere from $1800.00 - $2400.00! For the best Kit, at least as far as I am aware of, give these guys a call!
