So weird. I can't tell you my year calipers, I got the car last February. I'll ask Bill today. Here is an image of my front. For sure 19x9.5.

RCR must be using the 2016/up Camaro calipers with the internal cross over now.
Wasn’t there a discussion a couple of years ago about RCR changing the calipers in the kits to the ones with the internal crossover ???
I’m at dialysis currently, but will check into the search later today.

Here is all the information for my "front tire poke" issue.
Original Setup:
Original Setup:
- Calipers 2016/up (these have more room than the 2010 Camaro SS Calipers, the newer ones have an internal cross over)
- Hubs 1997-2008 Corvette part number K513139 - 5x120.65mm bolt pattern (Not the 5x120mm listed on RCRs wheel selection sheet) this matters for the semi concave!!
- Wheels 19x9.5 with a ~ 6.4375 back space - deep concave
- Tires Michelin Pilot Super Sport 285/30-19
- THESE DO NOT WORK!
- Calipers - No Change
- Hubs - No Change
- Wheels New - 19x9.5 +49, 7.2" Backspace Semi Concave part number F15199562P50 ~$485 in stock.
- Tires - New - Michelin Pilot Super Sport 265/30-19, Not yet ordered so I don't know how they will look. I will update when I get the wheels.
- The 2010 Camaro SS Calipers with the external crossover leave a smaller gap between the caliper and spoke. The 2016 and up with the internal crossover has about a 1" gap.
- The 285/30-19 Michelin Pilot Super Sport tires are really hard to mount on the 19x9.5" rim. First indication of problems.
- Semi concave is offered in the 5x120.65mm bolt pattern, this might fix the earlier year camaro caliper interference?!?
- RCR has wrong information and is supplying wheels that don't fit. The F14 Forgestar wheels do not fit. Not only do they poke out, the turning radius causes an interference on the body. Their order form for the wheels says 5x120mm when it should be 5x120.65mm and the offset\backspace is plain wrong. The suggested tires for the front, 285/30-19, "bulge out about 0.5" from the wheel, causing more issues. BE CAREFUL when ordering these wheels!!!

Great synopsis, we are all getting an education on the mystery of the Wheel Poke Syndrome.
I’m really surprised they have a 19X9.5 Semi Concave and do not have that listed as an option for a custom wheel. I went through this with both Logan and the Manager and they pointed me to the 19x9”.
If you do wind up with those wheels, perhaps we can figure out if they would also clear my calipers.
Anyway, looks like you have a good understanding and direction.

I got the wheels! Super nervous putting them on. I only have the wheels, no tires yet.
They fit perfect! Here are some pictures. This is at 0 degree camber. They are basically flush with the outside of the body. I guess I could have went a little more backspace. The semi concave really gives a lot more room.
Joel, I have about 5\8" between the spoke and caliper. Not sure what we should do to verify it works with your set up. I can make a few more molds??

Awesome!! Glad it worked out. Can you take a couple pics of the rims on the car, like a 3/4” view? My sense is you would not want more backspace since when you apply negative camber the tops will sit nice in the wheel well.
I have to give it some thought to figure out if these will work for my calipers.

Yes, the next step will be to get the tires. I am thinking 265 or 275. We have 285 right now and I think you got 255 and said they were too small. What are your thoughts? 265??
I am not sure what you mean by 3/4" view? I can take as many pictures as you need to see if they will fit. Heck, I could ship you one if you want or you could ship me a caliper.

Thanks Shane, appreciate the offer. I’ll do some compares of that wheel to Michael Route’s new wheels. He got the semi concave in 9” wide and it cleared the calipers. I have his specs.
Yeah, just a few pics so I can see how the semi concave looks vs. the deep concave we have. Like the view in my profile avatar.
Anyway, here are a few pics
Blue car - 255s
Red and Grey - 275s
Yellow car - 265s

Body Mounting:
I am now moving on to mounting the body. Wow, what a mental trap this is. It all seems to fit when it is just sitting there, but when you start measuring everything you sure go down a bunch of rabbit holes. Here is my first problem that I discovered.
I felt like my body was sitting in a good position and I looked at it from the front and noticed the roll cage was not centered in the front windshield.
When mounting the cage I had to use a punch to get it in the holes that were provided from RCR. They were about 1/2" off. When I took the front bolts out, the cage centered nicely in the front windshield. I am now going to have Swiss cheese for the A pillar roll cage mounts.
the next problem was the rear cage. The two mounts that sit on the lower cross brace were perfectly drilled. But when looking at where the spider was in relation to the back support mounts, I had about 1 inch difference from side to side. This took me down a crazy rabbit hole of measuring everything I could. I finally convinced myself that the body was sitting in a good position, but the cage still seemed off. I took the body back off and started measuring the cage. Sure enough the rear cage support mounts are welded 1 inch off.
The green lines are perfectly the same and the red lines are 1" off.
My rear angle braces fit, just with a big difference in the threads.
Does anyone see a problem with this? I am not sure if it will really matter, I am just trying to think of any other things that might not fit because of it??

One idea is to cut the mounting plates off the front roll hoop and make larger ones with holes to match up to the chassis. IMO, just leave the chassis mounting holes alone and adjust the cage.
Many of us put new plates on when we widened the roll hoops. Earlier SLCs had narrower roll hoops.

After the body is mounted, you probably should check if the ceiling panel clears the bars. If they are really off it may interfere.
Well, I heard it is better than the factory five GTM . LOL . But yeah, I can't disagree with you.
