anyone think Vette rims would fit?
Not without some work.....close, almost "RCH" close. (if you have to ask, google it)
Corvette is 4.75" (120.65mm) bolt circle (BC). The problem is the beefy 14mm studs will not bend readily to conform to the Corvette wheel BC, and that will put load on the hub flange, may distort it and cause wheel/rotor runout (wobble), and the tapered seats in the wheels would be heavily loaded on the inner side (radially) and inadequately loaded on the outer side--trying to torque the studs to 140 lb/ft would be an exercise in "what's gonna break first", among other potential issues.
If that explanation is confusing, let me try this--you could actually slip a Corvette wheel on to the SS. The studs on SS are larger, so that's the first potential problem. Since the BC of the SS is smaller, as the lug nuts are tightened, the tapered lug will come into contact with the inner side of the Corvette whee first, because the stud is not centered on the machined center(s) of the Corvette wheel. The uneven load on the tapered seat surfaces creates the problems mentioned above.
There are shops that can deal with this - Motorsport Tech
is a wheel adapter manufacturer that comes to mind. They can offset bore the existing wheel seats and install steel tapered inserts on any 4.75 BC alloy wheel to make them good for 120mm applications. I used them back when I was putting Camaro SS wheels on my 96 Impala SS (5x5 to 5 x 4.75) in the late 90's & early 2K. They used to be in SoCal, but have now relocated to Sparks NV - smart move!

Taking this one step further, when (you) say "Corvette rims" (wheels, technically), the reality is that through 60 years and, now, seven generations, the Corvette has used the same BC - 4.75", so you need to be specific about the wheels you have in mind--what model year?
FWIW, here are the C7 wheel sizes and offsets (NOT verified independently):
Front wheel specs - 18x8.5 (standard) or 19x8.5 (Z51) with 56mm offset
Rear wheel specs - 19x10 (standard) or 20x10 (Z51) with 79mm offset
It would be essential that anyone trying to fit Corvette wheels to an SS would be using something with "high offset" to mimic stock SS wheels, and to ensure adequate brake caliper clearance--so that will typically include C6 and C7. In the case of the C7, it would be necessary to fit both front & rear with wheels by using adapters. or by use of very long wheel studs, a custom spacer, and wheels modified as described above--when using adapters, they MUST be thick enough for adequate strength as well as to prevent wheel studs from protruding too far beyond the thickness of the adapter. Each adapter supplier has their own minimum specs in this regard.
Many OE Corvette wheels are hollow between wheel stud positions on the back for reduced mass, which leaves room for stud protrusion--this is not always true with aftermarket wheels that would otherwise fit late generation Corvettes. C6 wheel combinations are similar to C7 as far as offsets, and you can find that information easier since the aftermarket has been fitting wheels to C6 since 2005.
The minimum adapter/spacer thickness in the case of the OE C7 wheels, to place the wheels on an SS in "stock" profile (lateral position) would be 8mm for front (8.5 wheel width), which is really not thick enough for proper strength
- for the same staggered combination, the rear adapter (10" wheels) would be 22mm thick, which WOULD be enough for adequate strength. As there is at least 10mm of room to push the wheels outward (tire size dependent), a front adapter of 18mm and rear adapter of 32mm would mount C7 wheels on the SS quite nicely, if the offset numbers I've provided are correct.
The alternative--using 8.5" (C7 front) wheels for both front & rear would call for 18mm adapters, or something in the 18-23mm range, I'm thinking--and that still may not work as far as adapter thickness at 18mm
. Using 10" wheels F & R is probably NOT an option, even though adapter thickness (for strength) would not be an issue--it would be front clearance to steer the car without rub. While 2014 SS is not listed, Motorsport Tech lists the minimum thickness for an adapter for G8 GXP at 19mm (0.75").
Nothing would change with this minimum for the SS.
The only problem with most Corvette wheel setups today is that not only are they staggered by width, but they are not the same diameter F/R, where the sedan community focuses more on same diameter but different widths. Corvette gets away with it because the ABS system has been calibrated to deal with the F/R diameter differences--not so much with the SS.
The last consideration is that depending on model year, a staggered set with the right dimensions--especially offsets--typically do not offer a F/R set that match in diameter, which is the case with C7, where the front 19" wheel (8.5" wide) is Z51 style (10 spokes, in 5 pairs), and the rear 19" wheel (10" wide) is the standard (5 swept spokes) design.
If it was mine to do, and since a staggered Corvette wheel setup would not be rotated, I think I would modify the front wheels to correct the seat positions on the wheel (to 120mm), and use long studs (through the hub) with specific-thickness machined hub-centric spacers. On the rear, I'd go with an adapter setup (also hub-centric) and leave the wheels alone to do this the "cheap" way--if the car has no spare, this is a non-issue.
With a spare, it would at least cover the 2 rear positions by removing the adapter, but you'd have to wing it with a front wheel/tire issue. The spare wheel could still be installed on front, but driving should only be for a very short distance or to allow the car to be rolled onto a roll-back to get it home or to a tire shop.
