My car would drive straight for 2 miles too if I was on a smooth road. Unless we're talking about two different things, to me tramlining is how 'good' or 'bad' a car is affected by slight creases or cracks in the road. Some tires are softer (so they might tramline less) while some are harder (which might tramline more). I don't think it has to do with the car pulling random directions on a smooth as glass road.
I have a 2nd gen FX35 as well and the steering is numb and never have tramlining even with 285s all around and super stretched tires with over 4 degrees of camber. And LA roads specifically are s*** and make my daily drives stressful.parkstr8r wrote: ↑Thu Aug 09, 2018 4:16 amHi - I have had the tram lining you are speaking of when in LA. Part of it is the grooves and expansion joints in the roads there. The wider tires don't help it. I swapped tires in the past - explaining it to the tire shops so I avoided tires that would exacerbate it. The tires made a ton of difference. I still get a bit of weird steering feel with my 255's and spacers - so I can see the 285 sending a lot more feedback up front. To me, the front never feels as planted as I would like for some reason. Its an Infiniti thing as I had a version of it in all my other Infinitis - QX70S, EX35, and Q60S. The best feeling front was the QX70S.
I'm doing coilovers which will tone down the sports suspension feedback while adding control.

On a different note, your tramlining might be related to the clunking (I'll try to remember to deliberately test my M56 for this) or some looseness that's making your steering wheel constantly chase and try to catch up to what the wheels are doing.
When you said you were having to keep both hands on the steering wheel, was this a comment on vibration or plainly the effort needed to steer the car?

Glad you posted this! My Q70L with Bridgestones is awful. You are not the first person to mention this so I'm changing tires with the Spring "4 for the price of 3" offer.
Did they replace the entire rack and pinion? What exactly was the dealer solution? I'd like to fix mine as well, but I'm not in warranty, so I'm wondering what all needs to be done.
