If I get vibration at 120km/h (75mph) that isn't felt in the steering wheel, I would check rear tire balance/runout and motor mounts, then alignment after that ...see post 2

Step Three - Get new Tires ( I did all the above and found my front Tires were damaged, the belts were shifted, it probaly happend at the track due to Running Incorrect Tire Pressure)

I just came back from a speed run today and realised that my car produces loads of vibrations through the whole car but i dont feel it through the steering wheel.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi guys,
I just came back from a speed run today and realised that my car produces loads of vibrations through the whole car but i dont feel it through the steering wheel. The vibrations only become really bad at speeds 140km/h and above. Any ideas?
Cheers
well the first place to look is tires and balance, then wheels, then bearings, then drive shafts, then motor/trans mounts.....
you will most likely find its a poorly balance tire/wheel
- do you not drive it over 140 everyday?...
+1. The most likely - though not the only - explanation is a balance problem on a rear wheel. The issue could be that the wheel has thrown a weight or, believe it or not, simply that there's mud or some such on the inside of a rim.
If I get vibration at 120km/h (75mph) that isn't felt in the steering wheel, I would check rear tire balance/runout and motor mounts, then alignment after that ...see post 2
+1 what Ed says
additionally, check your tire pressures too. If you have not determined what pressures feel best for your car, tires, conditions, etc. try what the factory recommends.
Also, sometimes the road surfaces can contribite to how a car feels at speed. At 140 km/h the car should be very well behaved and not exhibit any negative feedback. 210 things start to get a little interesting and when you take your hand off the wheel to see how the car's tracking, don't do it for too long. 250kh/m, you should put the coffee and cell phone away and use both hand for the most part. It's normal for the front end to start feeling a little floaty and very slightly detached. Sorry but I can't report on what your car should feel like above this.
Step One - Check for Visual Damage to the Rim, Tires, Suspension and Control Arms
Step Two - Then, Get them Balanced
Step Three - Get new Tires ( I did all the above and found my front Tires were damaged, the belts were shifted, it probaly happend at the track due to Running Incorrect Tire Pressure)
