Obviously, if I were to drive the p!ss out of my car all day long there is more likely of a chance to have this tear occur. Autocross would also have more of an effect on this, but to how much of an extent? My mechanic hasn't seen anything (knock on wood, for the time being). He looked over the car briefly about 3-4 weeks ago when installing a new water pump to replace the broken one.
“I’m sorry, but having an Aston Martin DB9 on the drive and not driving it is a bit like having Keira Knightley in your bed and sleeping on the couch. If you’ve got even half a scrotum it’s not going to happen.”
