Hi there,
Just read a post of yours regarding upgrading the slave cylinder if you upgrade the clutch. I have a 2004 g35 coupe, (non-rev motor I believe). I recently had my friend who is a mechanic install the JWT clutch/flywheel combo package. My biggest complaint is the amount of force I have to apply to press in the clutch pedal. I literally get tenderness in the ankle from driving the car as a daily driver. After reading your post, would upgrading the slave cylinder make pressing the clutch pedal much easier? I have been going crazy trying to figure out whats wrong with the set up, then I finally came across this thread that seemed to finally address the issue I have been having. Thanks so much!
