Ordered adpater/spacer from a company that also customizes to exact dimensions I needed.
http://store.gaugemagazine.com/5-x-1...l-adapter.aspx
Per specs others have helped with via reading other threads, and advice from h018871 ... this adapter/spacer should allow the 2013 Camaro OEM Stock Spare tire and jack set I kept from my 1LT to work on my new 2014 2SS/RS with Brembo Roller Skates.
Here are the Specs I included with the order ...
Bolt Pattern: 5 x 120mm to 5 x 120mm
Center Bore: 66.9 MM (Camaro is Hubcentric, center bore should fit tight to the hub)
Studs: 1.5 14mm (American Made, Heat Treated, SAE Approved, OEM quality studs pressed into the adapters)
Spacer Thickness: 2.5" (exactly)
(it is 2.3" up to bevels on each edge, adding in the bevels it is a full 2.5" thick spacer, see picture with the ruler taped to side below)
When ordering I specified the car does not use Lug Bolts.
The five special lug nuts the spacer arrives with, have long collars on them which self center when attaching the spacer to the hub (see pic), locks the collars in to spacer very tightly.
When the weather breaks here in NC I'll try this to see if dimensions work out -- keeping my fingers crossed. Will update in next window when I get a chance to test.
Order Arrived - here are pics:

Side
Back Surface - notice all edges on the spacer are nicely beveled.
Lug_Nuts_with_long_Collar 14mm x 1.5 (thread) --- for attaching spacer to hub on car
Weekend is here! Sunday Weather Cleared, almost 60 degrees ... went out to test fit the Wheel Adapter/Spacer ...
Pulled the lug wrench, jack assembly, spare tire, torque wrench, etc. out of the trunk.
Here is picture of Stock Hub BEFORE Wheel Adapter/Spacer install. Note the center hub has a collar that sticks out (66.9 mm diameter) - Camaro is Hubcentric. Put a doubled-up cloth on the top of scissor jack so it wouldn't scape up the lip on the car's jack point.
This shows the wheel adapter/spacer installed on the car's hub. It fits precisely over the hub flange, no play, it is not loose at all.
Probably would stay on there without even using the lug nuts, ha ha.
View from another angle - in a previous picture it shows the special wide collar lug nuts that will hold this in place.
To torque you can put a screwdriver in a slot in the rotor to keep from turning.
Installed spare wheel/tire from my 2013 1LT on to the 2014 Camaro 2SS
In the first picture here I used the factory Camaro SS wheel lugs - rather large
Didn't seem right with those lug nuts so I grabbed some smaller profile lug nuts from spare parts bin.
Well turns out I only had 4 smaller lug nuts in the parts bin - so one stud is bare.
Next I spun the tire and it moved freely. Put my hand around back and felt 1/4" space between the outer Brembo roller skates and wheel flange. The 2.5" wide Adapter/Spacer is just the right width as h018871 recommended.
Unfortunately, I did not get to test drive. Had to go pick up the kids so quickly put the full-size tire back on. Need to also pick up another lug nut. I'm still trying to figure out what lug nuts are best to use on that factory spare wheel (has same size 14mm 1.5 studs on the wheel adapter/spacer as the factory Camaro hub)
