A few suspension/brake related concerns plz help
 

So I have a few concerns with my beautiful silver 370z:

When I brake (not heavily) and am in the process of switching lines or if there is any grooves in the road the wheel pulls hard in different directions. Like as if its the opposite of torque steer in front wheel drive its like brake steer or something.

Also noticed a slight vibration when braking at speeds around 70/80 when light braking. Kinda comes through the wheel but I can feel it in the peddle I think too. Is that just the abs pulsing. I have the sport brakes.

Lastly, when I turn the wheel hard left or right when turning line trying to 3 point turn or any time the wheel is relatively sharply turned it creeks/bumps its hard to explain but it's like the wheels are going over a gravel lot.

Any help or ideas what these maybe or if they r all totally normal and I'm just a over protective daddy let me know.

What tires are you running? This is common with sticky tires

Sounds like you may need your rotors refinished

Lastly, when I turn the wheel hard left or right when turning line trying to 3 point turn or any time the wheel is relatively sharply turned it creeks/bumps its hard to explain but it's like the wheels are going over a gravel lot.

Also common with grippy tires when they are not fully up to temp. Is this after driving for a while or usually right when you start and the tires are not up to temp?

As far as the pull when braking hard, have the toe on the front of your Z checked. Mine was toed out from the factory and acted the same way under heavy braking. Once I had the toe zeroed the problem went away.

You might have some "glaze" on the rotors. Try two or three hard stops and it will probably fix the problem. If not, you probably need the rotors turned.

I'm on stock potenzas right now. Rotors turned/resurfaced is wat I was thinking. And the toe issue Is a good idea but I did just have it serviced recently and it came with a tire rotation and balance. Would they have also adjusted the Alignment

Tire rotation and balance is different from an alignment. Unless you specifically asked for an alignment and/or paid for one, then my guess is that they didn't check the alignment. Also different machines for both processes, so most likely they didn't do it.
