ok so i was on genuinesaab.com and they have a suspension kit for like 600 and it says that its the one that goes on the Aero. would that be a better deal then buying konis or jsut new performance suspension. And would it be a big pain in the ***** to do it myself? Im really trying to understand the differances between the diff 9-5s. so im assuming the Aero is faster? bigger engine what not? so does that mean it has bigger brakes etc etc.... whats the size diff? between my 9-5 i think SE cause i jsut have the v6 and the aero? and all the other good info you guys are so full of.
