Good question, I'm not sure how to answer: I'd say the 9-3 we have gets through corners much more quickly than our 900 does, so in that way of speaking it handles much better. But then the tyres on this 9-3 are 2 cm wider than on the 900, the wheels are much lighter, and the shocks and springs much stiffer. So the tyres grip well but the rest of the car lurches around a bit so it's hard for me to sense where it's going to go if I push it over the edge. Our 900 breaks grip on the front pretty easily (was worse until I had the toe-in done) but I feel a lot more secure driving it because I can better sense where the limits are. Not having power steering means that the hands get a better idea of what's going on too. I'd say that our 900 handles worse than the 9-3 but is more driveable, due to the above reasoning. I'm beginning to wonder if maybe a stiffer sway bar on the back of the 9-3 would fix things. BTW is there anyone out there who has servo steering in their cars but wishes they could take it out? Just to start a discussion ;-) //Robert Four Weis wrote: > I saw that you also own an 83 900. Are you saying the 9-3 handles worse > than the 83 900?
