Chevrolet Corvette Forum : “c5 zo6 compared to c6 zo6”

i'd say go for the new Gran Sport package, hell of a deal, it offers the wide body from the Z06 but has its own distinct shape, aswell the GS borrows the Z06 brakes and dry sump (also in the ZR1), and suspension, since the 2007 you are looking at is a few years old, i believe the GS does have interior tweaks, LCD/ Nav system being the biggest. the LS3 in it is also hand built beside the LS7, LS9, and LSA enigine (used in z06, zr1, and cts-v, respectively)
though the Z06 does put out 505hp and Gran Sport 436hp, the GS will get you to 62mph in 3.9 seconds and it has a launch control (wont void the warranty either *GT-R cough cough**)

GS does weigh about 180lbs over the Z06, and will cost you a bit more than the 2007 youre looking at

from what i recall your C5 will produce about the same numbers (depending on exact year), so actual straight line performance gains wont be noticeable, around a track the GS might actually have the upper hand.


but if you are down right set on either keeping the C5 or going up to the C6 Z06, i would say go for it, like i said depending on your year, you will get a 100hp bump
