Grant: But at home, a track car only has to have Vmax of 225 kph.  So, if this car is a keeper I would consider a change to optimize the gearing for my slower track (where the GT4 will give many GT3's a challenge) and the tight mountain roads.

Grant, just for understanding: does that mean there is a general speedlimit in the US for trackday format events ?

As for the gearing: not a big technical isue if you want to do something about it later (though probably you put the warranty at risk). I did it with my GT3 (as so many other track oriented owners did) and I like it a lot - even drivers of nominally faster P-cars (997.2 GT3/RS) are biting into their steering wheels when I accelerate coming out of Adenauer Forst heading towards Metzgesfeld Smiley
