Only One thing so far.
If its wet or on a loose surface,when you are slow speed moving in full lock in either forward or reverse,the car hops or cracks on its suspension.Its very disturbing when it first happens as its quite loud (maybe amplified by the tub),but it was explained as normal as the car is so light at the front end,so im not sure wether its the unsprung weight catching up with the rest of the car or the other way round,watch out for it but dont be alarmed.

Is the tyre hitting the inside of the wheel arch?

That was my first instinct,but after asking Mclaren they explained that it happens to them all on loose/wet surfaces.
The dealership even tried it out on three cars to confirm it for me

Its very common on most cars and caused by a lack of traction and forced steering input. My AWD panamera does it really bad but is nothing to be concerned about. Turn the wheel less.

Yes cheers,i think what makes it different to other cars is the amplification created by the hollow tub being bolted direct to the front suspension,makes you think something has fallen off the first time it happens Also having driven 3000 miles in the dry it was something completely new to me

Almost all Audis do it. Even on dry surfaces.

My R8 does it on most surfaces. I thought it had to do with the AWD Quatro. I guess not.

very common on lots of high performance cars. Rear engine Ferrari's are particularly bad at full lock in reverse. I always assumed it was to do with the geometry of the front suspension. The SLR wont do it but its steering feels weired the rest of the time

CF tubs are very good on transferring any and all noise directly into the cabin.

Regarding the hollow tub, why don't they just fill it with expanding foam?

The sound it generates is only heard on the odd occasion,like riding catseyes or the above,so its not a problem really,and foam defeats the object of the lightness of the tub as im sure even though its light it would add a few kilos that have been pared away at great expense elsewhere
