My 370z is squirrely, need opinions/help

John Oliveira · 01-16-2012, 10:17 PM

Was able to get some good input but welcome more. Is your 370z stable on the freeway when the pavement is grooved or uneven? Ive got new rear tires (about 300-400 miles on em) 245/45 r18s and about 70% tread left on the fronts (225/50 r18s). All good tires, perfect alignment.......squirrely ride. Not happy with it and dont believe this is what our best new technology gives you. Where am I going wrong?

Maybe a break in period for the new tires? Strange. I have a roadster too and no problems here.

havent had any problems with my Z being unstable on the freeways around here or even up towards the LA area on the 101, of course i also have the sport package with the 19" rims all around so maybe that makes a difference?

Wider tires do tend to tramline more easily than narrow tires, but I haven't noticed any tramlining with my stock tires. If your tires are good, the only thing that I could think of that would cause it to be squirrely on any type of pavement would be the alignment. I have noticed it wanders more on groved roads, but never to the point of being squirrely. But again, if the tires are good, i would be checking the alignment.

On the particularly uneven areas of the road you will notice that the car will tend to take the track of the uneven pavement and you will have to fight it.

The wider the tires you have the more this becomes evident and it's completely normal.

It may be totally unrelated, but in my old S-10 the pitman arm and idler arm were both old and worn out, turned out there was some flex going on when I would turn the wheel. I could be going straight and hit a slight bump and my truck would jump in a different direction. There's a small chance it could be your steering components, but it sounds like it's just your bigger, grippier new tires

OP, if you've already made a similar thread on the same topic, no need for a 2nd thread bud.

Op,

Both threads have been merged since there is no reason to have two threads on the same topic.
