First off I want to thank everyone for taking the time to provide detailed responses and personal insight. I've been part of many different car scenes and forums and have never seen this level of true advice from fellow members.
After reading all your responses I feel it's best to answer a couple key questions:
1. What's your motor set up and will you actually be pushing enough horsepower for such a big tire?
I've already purchased and will be modifying a hybrid LQ9 6.0 longblock with LS3 heads. I like the idea of a N/A motor but have been contemplating adding some boost just to put that iron block to work. Ultimately my goal is around 600 and the motors current set up is pushing 530 last time it was dyno'd.
2. Am I dollar and cents guy or do I just love the idea of build awesome cars?
I would say I'm for building an awesome tuned and tweaked car but there's one problem - i'm under 30, and while having a ton of cars is awesome I still have to think about other responsibilities - like buying a house, etc. So I budget every build I do so in the event that something does happen i'm not out tons of a money. When everything's said and done and life's perfect then screw it tub it, stroke it, and tweak it to hell who cares!
3. So did I tub it?
Not yet but i'm going to! The car I bought was actually in the process of being turned into a drag car and I saved it from disaster. But some of the damage was already done so a fresh custom firewall tough enough for road race has been welded in with willwood drop pedals. Also the rear package tray was cut out so a mini tub isn't that crazy seeing I have to fix the rear anyways.
Right now the car has been stripped to the shell, media blasted and is about start phase II which is the rear - ETA end of November. I'll start a build thread once I get the car back and make progress on putting it together.
What rear-end set up?
After speaking with a bunch of people the last decision I made was to go with Chassisworks. This is due to the tune-ability of the rear suspension in regards to the 4 link position and the 16+ dampening settings. I've driven enough cars on aftermarket suspension both good a ****ty to know that having that customization is important especially when you like to drive the car regularly.
Also I've never been a fan of tucking my wheels down into the rim and i feel it just doesn't make sense when it comes to performance driving.
The rear end will be a custom 9 inch with a true trac 31 spline that I've already purchased and for wheels I been thinking about going with the below as they were highly recommended when i used to work with BMW's (I know there are mixed reviews about BMW pattern wheels on Chevy but for a wheel that is tough, designed and tested to handle BMW racing, and priced well it's hard to beat):
They largest they come in is 11":
