Will a 19x10 with a 79 offset fit the front of a C5 and not hit the arms and go full lock to lock? Don’t worry about the outer edge, the frame isn’t in a vette so I’m only concerned about the inner fitment.

Impossible to answer when you don't list the size of the tire being used. However, 79mm is too much. That is almost a full inch more inboard than OEM fitments. Most people running a 9.5-10.0" wheel with a 265-275mm tire are using offsets in the 50-60mm range.

What about a 19x11 front? With like a 9x offset?
My Front CCW 505 A's 19 X 10 with a 56mm offset tire is Nitto Invo 275/30/19
My 19x10 CCW fronts had +56mm offset so I really doubt whether that wheel with +79 would fit a C5 or C6. I doubt it would fit a First Gen Camaro, with aftermarket subframe, either. Only way to be sure, is measure the heck out of it.
What is a 9x offset?
like a 90-99 offset.

The tire isn't really a concern here, I'm concerned about the rim making contact with the A arms or tie rods and hopefully looking to get a 11" wheel on it so I can run some 315's. If I have to cut the fenders to get a 10" wheel to fit I'm making it worth my time to put a 11" under it.
For reference this is the car I'm working on. It's a '69 Camaro with a C5 frame. I have tons of room for tires since I'll have to make tubs after the wheels are measured and fit. Basically I'm trying to not have to cut my carbon fenders. The stock C5Z front don't touch by like 3mm, but when I turn then they make contact. I was hoping just a custom offset would get me what I needed to fit.
I'm also working on the rear fitment. This is a 20x10 with a 79 offset and it moved the wheel in far enough to not to have to cut quarters so far. Working on more measurements to try and get into a 335, but that might not work without some cutting.
If you guys are interested I can start a build thread on here since I'm using a Vette platform for my build and just in general its a bad *** build.
b) I agree with USAZR1. You should ask the pro-touring crowd. Many of the front suspension kits they use are utilizing C5/C6 arms/hubs etc. They can surely give you an idea of how deep the offset can be for an 11" wheel without hitting anything. My friend has a Chevelle with a Roadtser Shop IRS chassis and suspension that I think uses Corvette-style front components. He is slammed and runs a really wide wheel up front, but I have no idea what his offset is.
Have you asked these questions on Pro-Touring.com ? There's a bunch of First Gen guys that have already been there, done that. Most of the top chassis builders are sponsors on that site, as well.
If you owned a 64-72 A-body (Chevelle or El Camino), I could tell you what you need to know but First Gen Camaros are out of my expertise.

I'm on there and lateral-g.net. Unfortunately in this instance I'm the only one that has attempted this build with a vette frame. The other that are using C5/6 stuff are either narrowing the frame and steering gear to be running normal C5 offsets or making the body wider. Roadster Shop uses their own deign stuff and they start off with a narrower track width so they are able to tuck in wider wheels.
I know this can be done, I've just been trying to narrow down my measurements. I found a thread on here that says the max rear offset is 92mm with suspension limiters to control droop. I was hoping that someone had tried the same with the front to try and tuck big rubber in the stock fenders. On my C5Z I ran 315's on the front, but that was with C5Z 18x10.5's. I just need them to tuck in more than those did. Looks like I'm buying the wheel fitment tool soon.
Where there's a will, there's a way. Buying the wheel fitment tool is the smart move and when you're done with it, you can easily sell it to someone else.
However, it might cheaper and easier, in the long run, to use a Roadster Shop, Morrison, or Speed Tech chassis instead of trying to re-invent the wheel.
If I ever build another protouring ride, that's the way I'm going.
$1000 in 2 vette rolling chassis' or $20,000 in a roadster shop chassis? lol Plus this way I have my fuel system covered, and a transaxle.

Everyone I know who tracks their C5s and runs 315mm fronts on 11" wheels is running a similar offset to that of the C5Z 10.5" wheel. In some cases, they are actually running even less offset. Surely, this is done for inner clearance. So, chances are good that higher offsets like 79mm just aren't working. You may want to ask the same question in the autocross/road racing section, as those guys have tried just about every fitment..

I have a 19 x10 79mm C6 rear rim at home I will try it on this weekend, & get you some pictures, that rim is about 5/8" more backspacing than my 20 x10 with a 64 mm offset which has plenty of room lock to lock.

Buy the wheel fitment tool. They are very helpful with custom set ups like yours. It will save you time and give you the ability to try multiple set ups plus you can sell it later if you don't need it anymore.
As I promised, 79mm 19 x 10 this is set as close as I could get it to my ride height 1/2" higher than I run, I have 1" drop spindles & with coilovers I am 2.5" lower than stock at the front jacking puck location. As you can see no issues in the front, at the rear it only barely hits the lower control arm, it is not touching the jack at all. The clearance at back of the shock tower at the top is about 3/8"-1/2" I put 3/16" of spacer on after the photo, it still hits the control arm but it is so close to being at full lock.
Wow! Incredible job! It's going to be so cool when you're done. I love all the carbon fiber fabrication and the roof is amazing. I started a very similar project with a 2000 'vette and a '69 Camaro back in January of 2013. If you would like to PM me I could share some of the details.
19” front fitment.
