Man it's been a super long time out of the game . Hope all is well first of all and thank you for checking out my post. Trying to decide if a 13 or 14 cobra is worth buying. I see mixed drag times ranging from 12s to 11s stock. How reliable are they now that they are a few years old? I see the c7 z06s turning 10s stock and was thinking about possibly making the switch as It appears they have wider rear tires or can put wider tires then the shelby. I think 295 is biggest you can go? I had 315s with different rims on my 03 cobra and loved the width. Thanks guys again for replying.
