I think the C6 Z06 rear cradle will bolt up to the frame but will set the wheels back about an inch and a half or so. You might end up needing the stronger C6 components in the future. Not sure.
Well thought out but why the 20's on the back????? with a 25 aspect ratio, you will never hook up that HP to the ground. I would have gone with 17 inch on the back and ditch the 14 " eradispeeds for some stock diameter rotors, and fatter tires. 40 or 50 aspect tires. at least that Hp could be spooled up in the sidewall.
Not criticizing a beautiful car. but just questioning the need for all the HP and choking it off at the rear tires.
Good luck shaking out the bugs.. look forward to a finished project.
well done.,

it will put the rear wheels a tad further back into the wheel wells but it isn't that drastic, realistically it's more like a quarter of an inch or so... whether you choose to run coilovers or c6 lcas also makes a difference... c5 lcas and coilovers will not put the wheels as far back as using c6 lcas with standard shocks from what I have seen on other cars... there are also 2 c6 cradle variants, one with 2 holes for each diff mount and one that has 4 holes per mount which allows the mount to be used in 2 different locations but I personally don't think the cradle differences matter because once the drivetrain is in the car there's only one way to put the mount, you have no choice... the only reason I can think of as to why gm manufactured that cradle with the added mounting points is that maybe that cradle fits another car once the extra holes are added and it would be cheaper to do it that way rather than building a completely different cradle but I really don't know... here are a couple of before and after pics of my car, it is lowered a tad more now than it was in these pics but it doesn't really change the relation of the tire to the rear bumper... my rear tires are advertised as almost 28" diameter and I have no problems with fitment or rubbing the fender liner, I did however have to remove the inner brake duct to prevent rubbing
stock drivetrain and lg gt2 coilovers
after tr6060 swap using stock c5 lcas and lg gt2 coilovers
