If we ignore cost for a mo,I simply meant that tyres are so masively important to the handling of a car,you should get the best you can afford.As it happens,that seems to be the same as getting the most expensive!
Each to his own yes,but penny pinching on tyres when you have spent thousands on the car seems a bit daft to me.
I'm not experienced to realy know the difference between progreesive brake away and a tyre that lets go pretty quickly,but these things are massively important for quick trackday driving,so say the guys that know about these things.
Personally,I do as I'm told but when I swopped to SO2s I was quicker as the car was so much nore composed "on the limit"
hope that explains what i meant as I have more or less passed on the opinions of more experienced drivers than myself,so I struggle to explain it properly.
