1978 Porsche 911SC Spare Tire
1978 Porsche 911SC Coupe, Cabriolet, and Targa models require a 5x130 mm wheel and spare tire size that EZ Spare does not produce.
We've provided (spare tire only) fitment options below, but a spare wheel with the correct diameter, width, offset, bolt pattern, and hub size would be needed separately.
A spare wheel might be found at a used parts store from the same vehicle type.
Another more DIY approach would be to find a wheel from another vehicle with matching wheel specifications.
