air ride technologies is what i had on my accord....here is a link to their site....

and the tank, compressor and misc. parts came from suicidedoors.com but you can get air ride parts from suicide as well

honestly if i had the money i would have a air ride suspension on EVERY car i own because if you have all the right parts you can REALLY dial in the suspension but it gets pretty pricey....most just get bags or air struts and the basic components and call it a day but they use air ride suspensions on rally cars where traction is everything
