If you install the correct parts on the car it will fit just fine.
The tire is a 25.3" tall

thanks for your help.

I'll be happy to help you figure this out, I just want to check into a couple of things to see what we're working with. I saw up above where you said you used our alignment specs but can you tell me exactly what you have your camber set at? We ran a 275 on the 69 GG/RS Camaro that we just finished. We just need to see where your problem is coming from.

I posted the alignment specs above. What is the ride height on the GG camaro? Measured at what point?

get rid of the half height body bushings, that tucks the frame higher into the body

and that wheel backspacing (6.25 backspace) is more for a scott mock style frame that has the corvette arms

i think we are missing something in communication here.

I clearly do not have room to move the wheels and tires OUT 1/2". The fender is already sitting on the wheel practically. I'll get another picture later to demonstrate this for you.

Also not sure how body height bushings are going to create more side to side clearance in the fender wells.

Your first post says it is a 265/45 tire....

Won't half height bushings tuck the tire further into the fender and aggravate the problem?

What about adding a litte more camber?

Yep, 5.750 would put you into the fender.

I'd go -1.8 on the camber and see what you have to do to keep your turn radius. Looks like its in the sway bar hardware already.

I don't see a problem with the half heights in there. It's the same as lowering the car as far as clearence.

You're right, there's only so much room to fill. To get it off the fender, you need more backspacing, but that makes your frame clearance worse.

Looks like the wheel is already in negative camber. More would help, but you can't go to far.

The only way you're going to make this set up work is to raise the car a little, and notch the frame where the tire hits.

So are we saying that this set up (if used per Ride Tech's specs) works on some 69's but not others? Is there something "non-stock" about the G/RS set up? I'm looking for answers before I buy wheels and I have the same set up as what is being discussed here...except I have solid Alston stock height body bushings.

Could you post pic of the tire size? I'm not finding a 265mm tire in a kdw.
The standard height subframe bushing will serve to raise the body/fenders by about 1/2". You can simulate by adjusting the coilovers up to test fitment.
Also, additional camber will help fender clearance, help turn in for autocross ing, and will not significantly harm tire life
I routinely run cars with 1-1.3 degrees of camber on trips across the US. Theoretically that much camber will decrease tire life but we abuse our tires in so many other ways it doesn't matter.
