Sometimes, mostly at low speeds, my 8 pulls real hard to the left or right Is this normal? It always straightens back up but I don't think it should do that in the first place. Do you think the dsc has anything to do with it?

I remember seeing this addressed sometime in the past. I can't explain it so you may want to do a search. Welcome to the club.

 

tramlining. it's the road, and the fact that the suspension is tight. basically your tires are in ruts in the road caused by repeated traffic. You can't feel it on cars with softer suspensions.

 

You really notice it on roads with the little "rake" grooves in them, we have them all over the place here in socal. You really feel it when you have new grippy tires too.

 

people think letting go of the wheel to see if the car goes straight is how you find out it the car needs an alignment. WRONG. hold the wheel straight, if the car goes straight, no need to worry. there are "crowns" in the road that will cause the car to sway back and forth. even wind will cause an out-of-alignment feeling. low tire pressure on one side can even affect it.

 

Tramlining, yep.

that's a money find...nice work hoss

 

due to Rack and Pinion steering (powersteering with feeling :p) you really feel it (all sporty cars including all Mazdas)

 

man that drives me crazy too...but i guess thats the price you pay for a bad *** car like ours!

 

that is what happens when you turn the steering wheel

 

This phenoomina got noticeably worse, for me, after the 15K service. I think one of my (OEM Bridgestone) tires has a flaw. When rotated to the back, tire noise went with it and tramlining/unexpected left or right pull got worse. I ordered Pirelli which should be installed Friday! I'm hoping this will bring back normal handling.
