"No offense, but I own both an IS-F and a C6 Z06, and my Z06 is so much faster that it literally runs away from my IS-F... the IS-F is a sweet & quick daily driver, but let's be real. Frankly the IS-F actually feels kinda slow to me."
Well, I'm sorry for your "F" because maybe you dont know how to handle it properly! When your at a light put it on sport mode,in manual drive,with one foot on the brake and another on the gas pedal and punch it !!! Then see where your Z06 will be!!
