Re: Can alignment (camber) affect ride quality if the car drives straight?

Also, the protege (especially the miata) that you had is a lot smaller than the 3 (I'm not sure of the protege's weight, but I've seen 1700 lbs to 2400 lbs to 2700 lbs on the web..) so they will handle better than the 3. Even if the protege is the same weight as the 3, it will handle differently just because it's a different platform and it's smaller.[/quote]
When I meant that it should ride on rails I was referring to the car being more "stable" when even driving in a straight line (less feedback from the tires on a road that's pretty level, esp. from the rear). I would think if the car weight was higher that it would give you a better ride, just worse handling (turning, steering, etc.). All I know is the ride quality of the Mazda 3 is worse than my Miata and Protege 5. Sure those other cars give a rougher ride but I didn't feel other things in the ride like I am with the Mazda 3. Sometimes the car will ride fine and then others it seems the ass of the car is all wobbly for no reason - the front doesn't feel that way so the back shouldn't.
I'm just totally disappointed with this car's ride. If I can't find something to make it more feel more consistent ride quality wise then I'm going to have to trade it in before the end of the year. I'm not looking forward to that since I'm sure I'll take a killing on the car price, even though I paid less then invoice for it. It just sucks, since I really don't want to put more money into the car without knowing if the ride quality will be improved. Otherwise I'm just throwing money out the door.
Yes - this is a new 2009 Mazda 3 GT 5 door (Stormy Blue) with bose/moon roof. Everything is "stock" except now the tires are Dunlop SP Sport Signatures. Btw, the Dunlop's have a hell of a lot more zoom zoom feel when starting from zero. Feels like they grab a lot more road and sling you forward which is something the RSA's never gave me. And that's part of the zoom zoom feel that was missing. But the RSA's had better turn performance then the Dunlop's. I also had to inflate the Dunlops to 35 psi in the front and 34 psi in the rear (at night time cold tire temps. which should be higher psi during the day when the temp. is 20+ degrees higher) to get the tires to have similar steering performance.
