94 z28 upgrades
 

Hello all,
I previously asked about what all was necessary to upgrade on my car for me to properly run a 383 stroker NA.
I wanted to get an "everything else besides the engine" list going on.
I want to upgrade my front brakes to c5 brakes, and get 17 inch rims all around, and I want to upgrade my rear differential and suspension.
I have looked at UMI and found a lot of nice things on their site, and would like to go ahead and get all of your professional opinions and recommendations. I am looking for quality, while saving a buck when there is room to. I don't want to skimp out on something that could cost my life or my car. So,
What all do I need?

I see a front end kit with the k member and a arms, a shock and spring lowering kit, and a torque arm and drive shaft loop kit on UMIs website. I believe this would be all I need for my front end and suspension necessities, totalling $2420
I have looked around and I just honestly cant figure out what all I need for my rear end. I dont know if I need to just replace the whole thing, or if I can just replace the gears or the whole hog head. I dont know if I need different axels, or really how any of it works lol. I've found sets online and on Ebay, but I dont know if they are worth it. I typically see the 3rd member sold separately from the rear end itself. So if someone could point me in the right direction here I would greatly appreciate it.
