Understanding the Controversy Around Drilling Holes for the Corvette z06 Spoiler

Understanding the z06 Spoiler

The Chevy Corvette z06 is an amazing sports car that offers incredible performance andhandling. However, some owners have expressed frustration over the mounting of the z06's large rear spoiler, which requires drilling into the vehicle's bodywork.

The z06 spoiler is a crucial aerodynamic component that improves high-speed stability anddownforce. However, the factory mounting method requires drilling holes into the corvette'strunk lid. This has sparked debate within the corvette community about whether the trade-off isworth it for improved performance.

Why Drilling is Necessary for the z06 Spoiler

On the standard C7 Corvette Stingray, the rear spoiler attaches to the deck lid with adhesivewithout the need for drilling. However, the larger and more aggressive z06 spoiler cannot bemounted in this manner.

The z06's spoiler is designed to improve aerodynamics at high speeds by increasing downforceon the rear axle. This improves traction and handling. The spoiler is also raised higher off thedeck lid to allow air to pass underneath it for optimum airflow.

This large spoiler cannot be mounted with adhesive alone. The forces exerted on it at speed wouldlikely cause it to detach. The only robust solution is to securely bolt it to the deck lid with nutplates embedded under the fiberglass. This requires drilling pilot holes.

Concerns Over Drilling into the Bodywork

Some Corvette owners have expressed reservations about drilling into the z06's pristinebodywork. Key concerns include:

• Creating permanent holes in the deck lid
• Risk of corrosion and water ingress around holes
• Slightly altered appearance from noticeable bolts
• Potential for decreased resale value from drilled holes

Many owners want to keep their Corvette in flawless condition, without any evidence of boltedmodifications. However, others argue that the performance benefits outweigh these concerns.

Steps Taken to Minimize Impact of Drilled Holes

GM and Chevy engineers took careful steps to integrate the necessary holes for the z06 spoilerwhile minimizing their visual impact and potential for moisture issues:

• Used smallest bolt diameter needed for secure mounting
• Deburred holes carefully to remove sharp edges
• Applied corrosion inhibiting sealant around holes before installing bolts
• Designed spoiler underside to cover holes and bolts from view below
• Matched bolt heads to body color for discreet appearance

These measures help the bolted spoiler retain a clean, integrated look. The holes are only visiblefrom very close inspection behind the spoiler.

Aftermarket Spoiler Options Avoid Drilling

Some aftermarket manufacturers offer rear spoilers for the Corvette z06 that don't requireremoving the factory deck lid. These use high-strength adhesive and mechanical retention clipsinstead of bolts into the bodywork.

Key benefits of these no-drill aftermarket spoilers include:

• Avoid making holes in the deck lid
• Reversible installation without permanent alteration
• May offer even higher downforce than factory spoiler
• More customizable look from carbon fiber or color options

However, the factory spoiler remains the optimal choice for maintaining aerodynamic balance andintegration with the z06's design. The aftermarket spoilers may not provide the same high speedstability as the factory component.

Weighing the Pros and Cons of Drilling

So should you refrain from buying a Corvette z06 to avoid a drilled spoiler? Here are some factorsto consider:

Reasons to Accept the Drilled Spoiler

• Necessary for proper mounting and performance
• Carefully engineered by Chevy for minimal impact
• Visible only from very close inspection
• Unlikely to affect resale value of a collector car
• Preserves optimal aerodynamic balance

Reasons to Seek a No-Drill Alternative

• Avoid any permanent alteration of the bodywork
• Minimize any risk of water ingress or corrosion
• Maintain flawless appearance from all angles
• Easier to return to stock if desired later

At the end of the day, most hardcore Corvette enthusiasts will happily accept the trade-off. The z06is meant to be driven and enjoyed. For those prioritizing aesthetics over performance, anaftermarket no-drill spoiler may be preferred.

Maintaining the z06 Spoiler

If you do choose to embrace the factory z06 spoiler, here are some tips for keeping it in peakcondition:

• Hand wash around the spoiler rather than using automated car washes
• Carefully dry around bolt holes after washing to prevent water spots
• Inspect mounting bolts occasionally for signs of loosening
• Consider applying touch-up paint to any small scratches on bolts
• Remove spoiler before painting deck lid to ensure uniform finish

With proper care and maintenance, the z06 spoiler can provide lasting performance benefits andremain securely integrated into the car's styling.

Enjoying a Legendary Sports Car

The Corvette z06 remains one of the most remarkable high performance bargains money can buy. For many owners, the minuscule trade-off of four concealed bolt holes is a small price to pay for the thrill of owning America's premier sports car.

The z06's track-honed chassis and supercharged V8 deliver an exhilarating driving experience. This special breed of Corvette has rightfully earned its halo status in Chevy's iconic lineup. For those seeking extreme levels of power and handling, the z06 is a dream come true.

So take pride in those four mounting holes, knowing that the massive spoiler above them is an integral part of the z06 legend. The rumbling V8, tenacious grip, and head-snapping acceleration make drilling a few tiny holes into the decklid seem like a very worthwhile compromise.

FAQs

Why does the z06's spoiler need to be bolted on versus glued like the Stingray's?

The z06's much larger spoiler generates too much aerodynamic downforce at high speeds for adhesive alone. Bolting it directly to the car's structure is necessary to handle the forces involved.

Do the spoiler mounting holes cause corrosion or allow water into the bodywork?

Chevy carefully seals the holes and uses corrosion inhibiting compounds to prevent moisture issues. Proper maintenance helps avoid any long-term problems.

Does drilling holes hurt the Corvette z06's resale value?

Minimal impact is expected for such a minor alteration on a high-performance collector car like the z06.

Can you install an aftermarket spoiler without drilling holes?

Yes, some aftermarket spoilers use high-strength adhesive instead of bolts. But they may not provide optimal aerodynamic performance.

Are the mounting holes obvious or visible when installed?

The holes are concealed under the spoiler and are not visible unless intentionally looking up under the mounting area.
