I recently put new corsas on my GT2. My car is primarily driven in Greece, where the dry pavement is very slick(poor quality and very dangerous). I am amazed at the difference these tires have made. The traction and handling difference is unbelievable. And the wet traction is not bad at all maybe better. However one must be very careful of standing water where these tires are suseptable to aquaplaning. The lower speed rating of 290 kph is more than enough here. The tire pressures I run on the street is 2.3-2.4 bar front and 2.5.2.6 rear.
