I have my car since end Jan and drove more than 3.000 KM already. Driving between 80-130km/h the steering wheel vibrated a lot. In March I went back to the dealer. After checking the wheels and tires they found out that the P-Zero were not well balanced and I got 4 new tires. After this procedure the vibrations were gone. But! When I drive between 140-180km/h the steering wheel is vibrating again. Driving 230-250km/h the whole front of the car is vibrating quite a lot. To drive above 300km/h the vibrations are very heavy and very curios ( compared with my 430Scuderia). Anyone with similar experience at high speed?

Sounds like you need your tires balanced.

Sometimes the wheel balance weights detach.

Yeah, I've been up to 186mph (300 kph), and found the car eerily stable. Definitely no vibration in the wheel, and I frequently make brief jaunts up into the 100mph range that you mention.

Update1:
I got brand new tyres and wheels and tyres are well balanced. Now McLaren called me back as they want to change now the disks of my ceramic breakes. Maybe the problem is located there. I will report to you in due time abt the result.

Update2
It seems that the tyres are turning on the wheels and than they are not well balanced anymore. Now the dealer is glueing the tyres on the wheels. I will report the result

Never heard of that happening before delfs,maybe they need to have serrated rims like they have on the GTR,but i think thats to stop them rolling off rather than turning,but it would help:confused:

I have had mine up to 190mph and it was straight as an arrow, and then amazingly stable under braking back down to 30mph.

But

I seem to have small greek and groans in the cabin when the car is gently braking, going over uneven surfaces, and stop/start. Nothing major but annoying. Anyone else have this?

Thats normal,just at those speeds you can here the reaction of the suspension amplfied by being attached to the hollow tub

Thanks andy, but the greeks and groans are not at 190mph but at normal speeds even very slow speeds.
mine is the same,so im still assuming its totally normal,it was worse to start with,as a first car mine had less maluable bolts attaching it to the tub,they re-jigged that idea with softer bolts so the noise transfer was not as accute,but its more noticeable at low speeds as you can hear more,im sure your ears cant discern it at higher speeds because there is alot more noise going on.Still get it checked out if its bothering you,they might have got rid of 4 tough bolts on you by mistake:D
Somebody did have a hydralic problem early on that caused noise,but with no performance difference????

Update3: Glueing the back wheels and tyres were the solution. When the tyres were turning some mm on the wheel, than they were not balanced anymore. The difference was about 45g at the wrong place. Vibrations of the back has also been transferred to the wheel. So hopefully verything is fine now.

delfs,have they had anyone with this issue before,or is it just that you track the car alot????

They said that this problem is very rare. When I got a new set of tyres, maybe the put too much grease on the wheels.

I got exactly the same problem. They ended up changing the Carbon disk. The car drives ok now. Wondering if they also changed the disk for you plus glueing the tire to the wheel?

The had the intention to change the carbon disk, but after having glued the tyres on wheels the car drives correctly.

Just put a 600 miles not the car in Germany. The vibration problem returns but it is a lot more sever under certain circumstances. For example, if I accelerate from 130km in 7th gear, the steering will vibrate a lot. However, when I accelerate hard, changing gear at 6k+ rpm, the vibration is less. So changing the carbon disk does not completely resolve the issue.

Just wondering if you can describe the circumstance under which you got the vibration problem before they fixed it. BTW, what exactly do you team by glueing the tire to the wheel?
