The clutch of the 458 is designed to last the life-cycle of the vehicle itself. In other words the clutch will last until the transmission completely lets out. It was designed so that you can drive in any mode that you would like to, whether automatic or manual and in any manettino setting. Fluids will of course need to replaced over time, but being a dual wet clutch system you do not need to deal with nearly all the issues that arose in cars such as the 360 and 430. The new range of cars all come with what is considered a "lifetime guaranteed" clutch and unless you are a trained Ferrari technician good luck even getting close to the system.
