Agreed 19s are IMO just too big.
Remember that 18s were not approved for fitment on 964s by Porsche let alone 19s - bulletin issued.
The rolling circumference never changes as tyre profiles should always go down as appropriate but a reduced tyre wall will cause stress on wheel bearings, transmissions etc.
Having said that a lot of us run 18s on track with appropriate profiles - still not heard of an issue.
This is where stretched tyres are a bad idea as they effectively reduce the rolling circumference significantly which will cause the above stresses and throw your speedo reading out the window. That said, that bunch seem happy.

Wheels are rotiform SCR and are a 3 piece take on porsche winter wheels. They have now been sold to another RL member and I've moved on to a new set of rotiform. Thanks again for the kind words
