Can any one help me on the following in connection with the GT3 997?

1. What is the ground clearance is pretty low at about 93 mm which is lest than the C2S, C4S and Turbo.I am little worried about the "sleeping policeman" in London and also driving up a small ramp before getting to my drive. Do you GT3 owners/drivers exprience problems of hitting the deck and damaging the front spoiler lip or indeed the back lip??

2. Can anyone help describe the difference between the GT3 suspension with that of the the normal 997. Unfortunately I have not driven a GT3.

3. Is the Michelin pilot sport cup tyre the standard tyre. I understand that two tyres are available. What is the other tyre and how do they differ? How much milage does one get on non track use with the Michellen's. They cost about Pounds1,400 to replace.
