Hrm, I personally think a car should have matched tyres. But this isn't even half the problem, it makes me sad when people that spend thousands on their sporty car go out and decide they know better than the manufacturer when it comes to tyres to save a few quid, quite often ruining the balanced setup the manufacturer has created on the tyres supplied with the car.
My ST came with two P-Zero Rossos, and two Avon ZZ5s, I was appalled and will be replacing them with four CS2/3s at the earliest opportunity.
