I agree that running 10 or 11 seconds in the 1/4 mile is hard on the car,however as a daily driver the car only makes 500 whp and as a turbo car you can not use even that much power on the street,so the street driving is not the issue,the true issue is on the track.The harder you push the car the sooner something will break(everything breaks its just a matter of time). More power, more wear and tear on the engine and driveline components,less power,less wear and tear.You cannot push the car hard enough on the street to do any driveline damage.As I have already driven 20,000 miles on the street.I think the key to longevity is a great tuner that knows what the car can handle. The only real problem that I have encountered on the track is a blown clutch,I would have never blown the clutch on the street as you cant get enough traction on the street to do damage. With the AEM ems there are plenty of safety limits that you must activate to save your engine and you can even program some things to protect your driveline as well.
