A wheel adapter/spacer allows me to use the Camaro 1LT 2013 Spare tire set on my new 2014 SS (Tire/Wheel, jack, lug wrench from my old Camaro).
Size mis-match in the back can only be done for very short distance due to wear on differential -- must only use spare in front for longer distance.
Ordered adpater/spacer from a company that also customizes to exact dimensions I needed.
5 X 120 to 5 X 120 Wheel Adapter
Per specs others have helped with via reading other threads ... this adapter/spacer allows 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.
Here are pics:
Back Surface - notice all edges on the spacer are nicely beveled.

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.
It turns out that 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 recommended by others.
