I think they *probably* will
The rear rotors are smaller and on my van with 16" alloys, I can easily stick my fingers between the caliper and the wheel rim - It looks to me like there's a good bit more than 1/2 inch of clearance there and that's all you'd need
Go buy a 15" steel 5 x 108 wheel at the wrecking yard and give it a try - They *might* even let you jack it up and try the fit before you buy it
