I see that there is a 2001 Aero suspension selling on the saabnet classifieds for $350. How difficult is it to replace the suspension. Is anything else needed besides a good jack/jack stands, star wrenches, ratchets, etc? Aftermarket options seem considerably more expensive. I could probably sell my stock ones for some minor profit and do it fairly cheaply. Will the car handle oddly with the lowered suspension and my 16" alloys? The radius around the tire is about the same isn't it? The aero 17's are 215/45 and the 16's are 225/55.
