Anyone else have problems at highspeeds?

What do your tires look like? That can most certainly play a factor or it could very be that you've just never driven that fast in a sports car (no shade).

I have 4 Yokohamas and that can be possible it could just be me, I'm going to still bring it into the mechanic to have the alignment done

I have a sport with the forged 19" wheels, and I've found that the car is extremely sensitive to tire pressure. If it is a couple pounds too high (cold pressure btw) the car will seem to wander or drift in the lane at normal highway speeds. I dropped the pressure 5 lbs (found out I had a bad tire gauge...) and it was a different car - totally stable.

Get a good tire gauge and check the tires. Too high is just as bad as too low. The correct tire pressures are on a sticker on the inside of the driver door jamb.

Good luck!

Our cars have a very short wheel base. Any of the above effects the Z more than other cars. Corvettes have 8-9 inch longer wheel base just to aid high speed. Even the 350 is longer, just park next to one and you can see it.

Check tires/pressures, then take it in to the shop.

A couple of things come to mind; look at and measure the tread depth. If you are north of 30k on the car and haven't bought tires, then there is your issue, especially if you bought the car new. The factory Advans are only good to about 30k, after that, they get squirrelly as hell.



On a side note: Where in radioactive land (NJ) can you drive 80+?

65mph speed limit means you gotta do about 80 to not get passed. As South Park said "It's a Jerzy thing".

As for the OP, start with something simple. Check your tire pressure and go from there.

Haha thank you all for your input I really do appreciate every single post you all took the time out to post. And I don't do it often only when I have a OPENING road with no cars and where I know I can hit those speeds. We have a few major roads here where you can "safely"? Reach those speeds but not sustain it for a long time due to speed checkpoints, my car is going in today at the tire shop I'll have them check everything that has been posted in this log. Will give my diagnostics when it's complete

FYI, Mr. Onzedge is here to help

OP how many miles have you driven your Z? Prior to getting my Z, I was driving a 2014 Honda pilot(which has john deere tractor steering feel). When I first got the Z, the car felt super twitchy, I was holding on to the wheel with 2 hands afraid the car was gonna veer off the highway from a tiny bump in the road. Long story short, you may be overcorrecting. It took me at least 3-4 thousand miles to get fully adjusted to the Z. If you find no mechanical issues with your car this could be your problem. Follow the other members advice 1st...check tire pressure, alignment, have a competent mechanic check the car out.
