You know we have been told that but drive a car with a qa1 on it and compare it to others. Less squeaks and rattles. Is it as nice as some of the ones rated for road racing no. It was not designed for that but this guy daily drives this car and has daily driven it for years making nothing less than 9 second power since one year after it was bought. No cracks, no issues, no flaws. We've dealt with all of the k members too. This guy has no shit probably close to 30,000 miles on this car with this k member.
