Here are many of the items I have that were replaced by the X51 Upgrade. The car is a first wave 991 arriving in the states in Jan 2012, making the car a year old. The car had over 21,000 miles on it at the time of the items being replaced. All of the parts had standard wear and tear if any. No interest? No problem!
