So I'm going to order some 17x7.5 Oz Racing wheels on Saturday for my Mk7 FiST and was looking at Michelin Pilot Sport 4's as my standard ones may have a years life left.

The only size I can find that's closest is 215/40/17. My understanding now is that this is going to make the overall tyre height taller than the standard tyres (Australian/Euro spec car).

Can anyone tell me how much difference will it make to the speedo at say 60-80-110km/h?

Thanks in advance.
