Trag said:Just to let you guys in on something a shop in miami is doing an air setup for a p11. the front will have pistons and the back will have air bags. thi is why, the front has a long shock so the piston rod has enough play there, how ever the back will have bags because when the cylinder rod is compressed the car at stock height is slightly higher then the piston its self. there for having bags in the back will allow the car to tuck a lot more, on a stock tire the cr is tucking about 1-2 inches. i know this cause ive seen it on a P11 that there using to test it on. basically the piston is too big for the rear in a P11 but its better for a P10.
