i was just wondering when you guys are going fast when does your car start to shake or start to seem or feel uneasy.

 

depends on the road. if the road is perfectly flat and its not windy around 140

 

I get no shaking at all at around 150 - 160.

 

at 120, mines gets kinda floaty when going around a bend

 

It all depends what kind of suspension and wheels and tires you have. If you tires arn't balanced properly then your car will shake. I have had mine up to 250kph without any shaking or vibrating. It was solid at that speed. If I had more ***** and more road I would have seen how fast she would go.

my car gets a shake at about 65 cuz some fool hit my car at a party. thing is, they only hit the wheel. so I have a hop in the wheel now. then the jerk took off so I couldn't get there insurance! anyone have a stock wheel for sale?

before that, my car felt a little uneasy at 14-, around the fastest I've taken it. or maybe it was just me feeling uneasy? The car actually felt confident still.

 

Smooth and stable at (a speedometer indicated) 170 mph

 

If your car shakes, then you need a balance and/or and alignment.

Your question shouldn't be "when does your car shake"
Your question should be "Why does MY car shake"

 

at 155 the only thing that stopped me from going faster was the fact that it takes a while to accelerate from that speed.

I didn't want to be going 150+ for over 30 seconds in a row

Didn't notice any problems with the car but I was worried that at that speed my shitty tires could kill me
Is it safe you think to be doing that on kumhos?

 

Vibration can also be due to a bent wheel. The cool thing is, they can be fixed.

 

It depends if the tires have an appropriate speed rating, Z or W ratings are good for just about any speed

 

150 and solid...stock suspension.

pulling hard too, just got scared and let off.

 

indicated 170 at night, i got scared and let off, but it didnt feel like it was floating,

 

150 felt good to me! no shaking or floating.

 

How do the no 'wing' guys fair at 160mph? I havent taken mine past 140mph yet but it felt solid. (Im wingless)

 

Wow, I've only been up to 120mph, and that's because of my boost leak (3psi) and I ran out of road. The car did feel fine though.

 

No shaking but lots of buffeting around the a-pillars beginning around 140 and at 150 the windsheild wipers appear to be trying to leave the car

 

I noticed severe buffetting at 140. Of course both windows were down... Could even see the hood shaking. But the wheels were in balance (the steering wheel was steady) so it seems like turbulence was the cause of the shaking in my case.

 

Solid at 160+ mph. If you are getting shaking at any speed, you have a problem- wheels out of balance/alignment, driveshaft problems, bent wheel, etc. Best get the problem fixed. Losing control at triple digit speed will be something you will always remember- if you live through it.

 

I noticed by head shaking a little when I have the windows down at 140. I guess I should keep it INSIDE the car.

 

I thought your head was too big to fit inside the car?

 

my side view mirrors start to shake at over 100. do all fds do this?

 

Ditto

 

My car feels as smooth at 160 mph as my daily driver Acura at 55 mph. I go up over 150 pretty frequently and I've never felt that the car was shaking at all.
