Hi all ,had the Z a week now and just getting used to it the only complaint I have is excessive tyre noise (well I think its tyre noise,  ) and a bit of resonance through the cabin...it is running bridgestone potenza tyres..Is this normal ? if so anybody fitted any brand of tyres that cuts this noise down ?  
         Other than that it is a brill car  ,a bit loose on the back end in this damp weather   but thats only to be expected   ,any comments gratefully received  Cheers Tim
