These are the best money can buy. They are ride hight adjustable with air. You DO NOT need a compressor to run these. They have 0 miles on them. I bought them and mounted them, then removed since the car is for sale. They are new. They are $1600 plus I will include the air lines. You basically can mount the air valve any where you want and add/remove air to adjust hight. These do no leak so if you get a desired hight you can just leave it there, they are performance shocks. Not a "bagged" setup. Being triple adjustable they will be great at the strip also. $1200 shipped.
