Sorry to revive an old thread, but I’m experiencing a similar issue with my 370Z Nismo.
My tires are skipping badly, and I hear a metallic clunk when the car judders. The clunk seems to come from the front and it’s especially noticeable and embarrassing when leaving a car park.
I’ve read about the Ackermann effect and cold tires, and people say it’s normal and unavoidable, but it feels worse lately. My PAS fluid is fine, and I’m currently running Pirelli P Zero tires, which have hard sidewalls. I don’t recall noticing this issue with my previous tires (Michelin PS4S or Dunlops) in the past five years of owning the car, so I’m considering switching to softer tires to see if that helps.
I also notice some noise on full lock when driving up or down the spiral ramp of a multi-story car park, even with warm tires. My tire pressure is set to 35 PSI front and back.
Could alignment help reduce the skipping?
Lastly, after driving a rental car for a week, I noticed my steering felt stiff when I got back to the 370Z, but it seemed fine after a few days. Maybe it’s just the nature of the car.
If I ever decide to sell the car, this could put off potential buyers, and I don’t think they would accept “it’s normal for this car and it's just physics ” as an argument—I know I wouldn’t. Looks like I’ll have to sell it in the warm summer, lol.
I’ll try to record a video and add it here later. I’ll probably take the car to a garage to have it investigated, but I was wondering if anyone here has managed to fix this. As I mentioned, I didn’t have this issue before, so it doesn’t seem normal to me.
Any thoughts or suggestions would be greatly appreciated!
Thanks
