You are talkin to the worst person when it comes to upgrades, my answer to my wife is NO why would you change a great car like this?? then you do your best sales job, and it actully hits the driveway, then proceed to change everything (within reason) that you can. Yeah, I like to modify things, GM really put a great car together in the C6, IMO, this is the first "brand new" vette I ever bought, sure worked on em before this, It's such a great car, IMO just needs some slight tweeks, I want 450/475 HP without the ZO6 price tag. Taking nothing away from the ZO6, I know there is more to it than the HP, but I want to have fun tweeking my LS2, would love the ZO6 just was not for me (and the mrs. In the cards) need the top down in huricane central Florida.
