Steering Wheel Shake Between 70 MPH and 80 MPH
 

Hello Everyone, I have just installed new 20” wheels with lowering kit (1” front almost 1” on the back). I have taken the car to where I got the wheels and they have laser balanced the tires/wheels but when I hit 70 MPH the steering wheels has a very small shake, it happens between 70 and 80, once I’m over 80 the shakes goes away. I have put back the stock wheels and tires and still shakes at the same speeds.

I have done a bit of research with very little results, some say it’ might be the tired rod, some say it might be the struts.

Team, please advise.

Thanks,

Yoshi

Sorry I was told I was on the wrong forum on the other one, to post it under wheels and tires.

Well you have to understand that with larger wheels, you have thinner tires. At the same time, you can't expect the same ride once you switch out the wheels. My Z does the same exact thing...

oh man, a bit sad about it but thank you for your feedback.

was there noticiable shaking prior to the s-tech install?
there should be no shaking regardless 19" or 20" wheels.

i think somthing's up with your front struts.

did you install hub rings?

shaking's still there with stock 19's... apparently

There was no shaking berfore the mods, mind you I did it all at once, wheels and springs. I just cant believe that there would be a shake just because I'm using 20's. Something is not right. thank you All for your input, I'm getting frustrated.

i recommend you check your struts for leak. also loosen tower and bottom fasteners and re-tighten with the vehicle weight on the suspension.

it shouldn't matter 18, 19, or 20. there should be no vibration.

Excellent Kenchan, I will get that checked, its just annoying to drive it with that little shake. All feedback is welcome, I just want to get to the bottom of it. Thank you All.

Could it be the wheels need to get re-balanced?

wheels have been laser balance and even changed tire brand to see if that was an issue. thank you.

I would get that balance redone somewhere else first.

+1 on did you install hubcentric rings with the wheels?

Here you go. Hub Centric Rings - JustForWheels.com
our 370z size is 66.1(inner) you will need the outer size. most likely 73.
