The ZR-1 was available in coupe form only. There are rumors however of special ZR-1 convertibles constructed for top GM executives.

Above: The 1990 ZR-1 benefited from distinctive styling from the rear in the form of a convex as opposed to concave bumper shape. The stylists probably figured the back end would be the most common view other drivers would have of the ZR-1.

Right: Round tail lights had been a Corvette tradition since 1963, but the rule was bent for the 1990 ZR-1.

John Cafaro, Studio Chief of Chevy Three where decisions about the ZR-1 shape was made, said this about the square/round shape: "A designer is always trying to push, reach out there a little bit without losing the heritage of the car".

To competently couple all 375 hp to the ground, (below) the ZR-1 got 11" wide wheels (the L98 engine Corvettes had 9.5") with P315/35ZR17 B/W tires at the rear. To accommodate the larger shoes, the rear of the ZR-1 was 3.0" wider. In addition to the rear clip, different doors and rocker panels were required. Some careful observing can reveal the differences - a clue is where the band that holds the rear of the Targa roof meets the body, as there is more horizontal area on the body of a ZR-1 at that point.
