Great questions and feedback. I appreciate everyone's insight. I am currently modifying my 2005 350Z and am recording my findings. I purchased a digital postal scale so I could weigh the parts. I am recording my performance findings on my YouTube channel- Rob Review (https://www.youtube.com/channel/UCr-oIm ... 1tp7EfYKyA). Find out more and leave me feedback:
