In my recent and impressive road test of the 12C, I did notice ride thumps from the chassis especially when driving over speed bumps. there were many positives that I took away from the 30 min test but I must admit the thumping was slightly grating.

In my search from the automotive media to get a better undertanding of what is going on here I came across this article which better encapsulates what I felt.

Would be interested from other owners experiences if this characteristic is just an isolated issue

See the thread..front wheel "knock"

You know what, I remember feeling that way the very first day I had the car. But I've since completely forgotten about it. So not sure if that is because I'm used to it, or my car no longer does it. I will have to pay attention on my commute Monday and report back.

I found the same thing on a test drive going over a speed bump. It was a bit disturbing.

That is chassis stiffness for you. No worries here.

Could be something else... but most likely carbon tub acting like a drum.

All sport cars will hit their suspension travel limit (heck I have 10" of travel on my Ford F350) but the sound will be more pronounced in a carbon tub. My GT3 Cup car (race car) with no sound insulation would bang! loudly at pot-holed tracks such as Thunderhill.

It is part of the charm of a CF tub. You will stop noticing it after a couple of days.

Agreed, the noise is there and unnecessary IMO. It would be nice if Mclaren chimed in just said hey guys and gals, it does this because.......

Or, this is a product of the hydraulic rams on the carbon chassis and the chrome plated muffler bearing reacting to the chingilater sphere.

Anything to address the underlying questions we all have, as Mclaren owners and drivers, IMO, are more astute and educated about the product and the driving dynamics.

It sounded to me like the suspension runs out of travel. An official response would be nice. Saves the speculation...

iT REALLY becomes irrelevant as you build miles. I have done two long distance tours, 2000 and 3000 miles, and it recedes into the background but if it GOYT's then it GOYT's.
