Your thoughts about keeping the Z and adding power sums up my own. A GT500 and I were having fun, and even that guy gave me a thumbs up and a "not bad" look on his face afterwards. It looked like a 13' by the black middle tail lights and the front HID lights (plastic hood vent too). All I know is it was fast as f@ck. While I was spinning through 2nd, he was hooking and moving out. When he tucked behind and I mashed it, I was surprised to see he didnt reel me in. I then gave him the thumbs up and "not bad" look for good measure. Point is, power was all she needed
