@ GMB patience is a virtue, and pay attention in future please, I know all about your driveway you obviously need this http://www.350z-uk.com/topic/82668-brand-new-extra-low-bc-racing-coilovers-and-static-air-cup-kit/
@ Wasso, ain't going near that road again, least not in my Zed
@ Big Neilly, little or nothing at motorway speeds, almost wouldn't know it was there, have had to adjust my gear changing a little at lower speeds when pootling about in traffice, low revs and premature high gear (which was never an issue with the Milltek except in 5th and 6th) equals some drone but nothing to worry about and easily avoided. In case you missed the earlier stuff I'm running standard cats now.
@ everyone else who has been complimentary, thank you.
