i have a 2007 nissan 350z its all stock and i was wondering if the kn came in a set of 2 or is it just 1?
Yes, you should get it checked out. You should also take a MSF training course and pay particular attention to the braking exercises and then go to an empty parking lot and practice.
If you are riding with tyres and brakes that you cannot trust then you are practically begging for another accident. Get them checked/replaced.
