Some C7 owners with the competition seats complain of varying degrees of discomfort including pain in the upper left leg during long drives. I picked up my Stingray with competition seats last August 17th but did not drive it for more than an hour until early September. It did not take long to become aware that my left upper leg was very uncomfortable and after 3 hours it was indeed painful. It felt like a hard pressure point from the left bolster - the right side was ok. Didn't give it more thought until this spring when the pain became evident again. I did not find any reports of discomfort on our CCF but on the USA forum it was a major topic of discussion with several potential fixes. I was at a point of frustration with the discomfort and tried one of the solutions on the USA forum - it worked. Problem solved no more pressure and the seat is comfortable. If any of you have experienced the competition seat left leg pain syndrom this worked for me: C7 seat thigh pain fix - CorvetteForum - Chevrolet Corvette Forum Discussion. It is quite easy to do and does not affect any other aspect of the seat operation.
