Price: £320.00 - £329.99, Tyre Size: 225/50R16, Width: 225 | Porsche 928 S4 1987 to 1991

Originally fitted with a 225/50ZR16 radial front tyre, and a 245/45ZR16 rear.

The S4 was the most dramatic update to the 928. It brought the car into the late 80s very effectively, with a new, larger, 32-valve version of the V8 engine, sophisticated management, and a new automatic gearbox. These changes were reflected by a comprehensive update of the styling, improving the aerodynamics, as well as smoothing the looks. It no longer looked like a 70s car.
