So I want a new car that does a better job communicating. I find this article to be very well written. The control issue they talk about re: the M coupe is exactly the type of stuff that I am looking for info on. I am very interested to see what EVO has to say in their annual car of the year issue, in which I expect the M coupe to be a participant.
Thanks again
Michael

The tyres were a critical component to change. Conti SportContacts were a pretty poor performance tyre when they were originally produced 5 years ago, and nowadays are leagues behind something like Michelin's Pilot Sport 2. Most of the comments about the Z4M, including the understeer, uncertain feel of the front end and an inbalance between front and rear axles are caused by the lack of mechanical grip and progression at the front axle.
Additionally I also fitted BMW's standard Z4 front strut-brace, which stabilises the front end alignment (and thereby increases confidence). Finally I fitted the Michelin PS2s on to 19" wheels which are around 15lbs lighter than the OEM wheels/tyres, which by reducing unsprung weight also improves ride and compliance.
Simple obvious changes that make a very worthwhile difference - and clearly BMW should have included this configuration as standard. It still doesn't 'breathe' as well over the surface as a Cayman, but that's the only area where the Cayman pulls an obvious advantage. The Z4MC in turn is more agile, quicker and is tremendous fun when taken over the limit. Each have an interesting set of characterstics that will suit certain drivers and define their preference.
