It will last awhile in your Cobra, being a lightweight car. But the more hard passes you put on it the more risk you take, esspecially with slicks. The point that will break in the T5 will be 3rd gear, not second, that is when your torque is being put to the ground and your tires stop spinning. All that being said, you can not put an life span on your T5 because alot of it depends on the way you drive it, the easier you drive it the longer it will last. But like stated earlier when it does break you can either have it upgraded or go to a TKO600.
