Z06 Corvette Review, Pt 1 – The 1963 Z06 Racer Kit

Published on by Scott

For “Off Road” Use Only!

DATELINE: 3-19-22, this story first appeared in the January 2017 issue of Vette Vues Magazine – The C8 mid-engine Corvette is arguably the biggest news in the world of Corvettes since the very beginning in 1953. Many of us thought Chevrolet would never offer such a Corvette, but here we are. And thanks to an established pattern of performance track-model Corvettes that started in 2001 when Chevrolet decided to brand the car, “Z06” after the one-year-only 1963 Corvette, subsequent new model Corvettes have offered a Z06 model. Within minutes after the C6, C7, and now C8 Corvettes were debuted, fans’ second question (after “how much is the new Vette?”) is, “Where’s the Z06?” Yes, we expect it and Chevrolet has not let us down since.

As of this writing, Chevrolet has their Traveling Road Show in full-swing at select Chevrolet dealers to show the loyal faithful exactly what the new C8 Z06 is all about. On March 25, 2022, Stingray Chevrolet, in Plant City, Florida will be hosting their C8 Z06 presentation. No doubt, owner Steve Hurley will put on a fantastic presentation.

So, with that in mind, the next dozen or so posts here on Corvette Report will present stories I have written for Vette Vues Magazine over the last ten years about the Z06. The C8 Z06 did not arrive from nowhere, there’s been a progression of Z06 Corvettes that go back nearly 70 years to 1963 when “RPO-Z06” was an obscure, one-year-only “racer kit” option that Zora Arkus-Duntov seeded into the 1963 Corvette option list that was essentially a “suspension and brakes” option on top of the L84 Fuelie. There were no external badges or special body enhancement and the car looked like any other Fuelie Corvette. And truthfully, unless a customer wanted to go road racing with their new Corvette, the Z06’s performance suspension and brakes were of little value on the street. There was no fanfare and after 1963, no one but Zora and his hardcore racer friends missed the Z06, so the Z06 faded into Corvette history; that it until the release of the 2001 model year. Ever since then, the Z06 was THE track weapon for Corvette racers.

So, let’s have a look at how we got to where we are with the C8 Z06. It is arguably the most exciting story in Corvette history. – Scott

When I was a wee lad and would see the term, “For Off-Road Use Only” I used to think, “Well who drives these cars in the dirt and grass?” What I didn’t understand was that the term is code for “RACING”! Beginning in 1957, Chevrolet’s new general manager, Ed Cole, made the command decision that he would let “customers” carry the Corvette racing mantle by offering Chevrolet-engineered parts, specifically designed for racing, available through the Chevrolet Parts Department.

First-Ever 1963 Z06 Corvette Stingray – Dave MacDonald Picks Up, Then Races Z06 #684 At Riverside

Published on by Scott

The First Z06 Corvette Was a Race Car!

Dateline: 8.30.15 – The original Z06 was Duntov’s “racer kit” for the then-new 1963 Sting Ray. Unlike modern Z06s, there was no flash to the first Z06, it was strictly hardware designed for the racetrack – no badges, special body panels, or designations at all! But considering the official “we don’t race” policy of GM, 199 1963 Fuel Injected Corvettes with heavy-duty brakes and suspension, wasn’t anything in GM’s big picture. But, if you wanted to race your Corvette in ’63, it was everything, and Duntov made sure you got what you needed.

Thanks to the SCCA rules that allowed the 2000-pound Cobra to race against the 3100-pound Corvette, even with the Z06 racer kit, the Vette was at a serious disadvantage. Continue reading “

Corvette Timeline Tales: July 1962 – Production of the “Lightweight” aka Grand Sport Begins

Published on by Scott

Dateline: 7.27.11
This could have been the beginning of a grand adventure for Corvette racing!


This is how we tend to think of the ’63 Grand Sport Corvette, with its aggressive fender flares, scoops, vents, and fat racing wheels and tires. Initial production was supposed to be 100, but Duntov envisioned at least 1,000 Grand Sports!

For those of us who are fans of the early days of the Corvette, the name, “Zora Arkus-Duntov” casts a very long shadow. GM’s chief of styling, Bill Mitchell once referred to Zora as, “Just a lowly engineer on a low-volume production Chevy.” While that may well have been correct, thanks to friends in very high places inside Chevrolet, Duntov got away with some astonishing things. And the Grand Sport wasn’t the first or last bodacious stunt he pulled.


There wasn’t much under the thin fiberglass body. The car had magnesium Hallibrand knock-off wheels,  an aluminum bell housing, transmission case, and rear differential, plus a 36-gallon fuel tank. Note how the side pipes came off the stock cast iron exhaust manifolds. FIA rules mandated that the cars carry a spare tire. (GM photo from the book “Corvette Grand Sport” by Lowell C. Paddock)

For this adventure, Duntov’s GM “angel” was Simon “Bunkie” Knudsen. While Bunkie personally never raced cars, he did work on the GM assembly line as a college student in the ‘40s and was passionate about race cars. While general manager at Pontiac from 1956 to 1961, Knudsen was responsible for Continue reading “Corvette Timeline Tales: July 1962 – Production of the “Lightweight” aka Grand Sport Begins” →
