Have a 2001 540iT Wagon, base suspension, 16" wheels. Also have a 2002 530i / 5spd M Sport. I truly love the way the 530 handles and corners but have to say the wagon has a much better (comfortable) ride. Also the wagon is fast as stink and the constabulary doesn't even look at it .....

My question = I just put the winter Generals on the stock wagon wheels and am going to put a set of either 17's or 18's with summer rubber on in the spring. I know the suspension is different on the wagon so lowering it really isn't an option. Is there an aftermarket sway bar and shock setup that I should consder to give me better cornering and response ? I truly love the wagon but am beginning to regret that I didn't hold out to find one with the Sport suspension....

Any advice from anyone who has "been there and done this" will be much appreciated.
