Expect a 6K bill for the new diff with install unless you can find a used one and also find a cheap place to install it.
I've spent over 35K on performance modifications alone. I don't know what the heck I was thinking (could have bought a ZR1 or C7Z instead). BUT, I love my C6 Z51 Vert' and plan to keep her forever (it was my 1st real sports car I bought during residency and has a lot of sentimental value/great memories). PLUS, having a base C6 Convertible that dusts a C7 Z06, C6 Z06 and ZR1 is priceless. Oh, and that SOUND!!!!!

HP dyno tweaks are one thing, but its the reaction times of fuel/spark, and even TB opening rates of the ECM (what Hp tuner and EFI live will not mod on a tune) that the is holding the motor back for a great deal of power to begin with (now allowing the motor to instant rev to redline, and instead the slow ramp up that the motor does now to save the drive line/make the car soccer mom drive able instead.
LS2 base motor in the vet makes 411hp, and not the 390hp of the truck motor in the below video.
So again, de-soccer mom'g the ECM mapping in regards to response times and limits, so the motor will instant response/ instant rev to red line on demand, makes a huge difference to start with.
