What We Love About Walt’s Build
Walt’s Corvette Z06 stands out with its clean design and functional upgrades. The C8 Z06 Z07 Front Splitter adds an aggressive look while improving airflow and stability. It pairs perfectly with the Hypersonic Gray finish and carbon fiber wheels, creating a cohesive, high-performance style.
The C8 Z06 E-Ray Rock Guards are another smart addition. They protect the car’s paint from road debris while maintaining a sleek appearance. These pieces are both practical and stylish, showing how small details can make a big difference. Together, these mods give Walt’s Z06 a unique personality that’s both bold and refined.
Mod List

C8 Z06 Z07 Front Splitter
The front splitter immediately grabs attention. Its Carbon Flash Black finish contrasts beautifully with the Hypersonic Gray paint. It stretches across the front, giving the car a wide, aggressive stance. The sharp edges flow naturally with the Z06’s angular design, enhancing its sporty appearance. The splitter makes the car look lower, more planted, and ready for the track.
This splitter is both stylish and functional. It improves airflow under the car, adding stability at high speeds. The Carbon Flash Black finish ties in with the factory accents, like the mirrors and side vents. Walt’s choice creates a balanced, professional look. It’s the perfect way to boost the car’s performance and style at the same time.

C8 Z06 E-Ray Rock Guards
The rock guards fit snugly against the wheel wells. Their design is subtle yet effective, blending seamlessly with the car’s lines. The Carbon Flash Black finish complements the splitter, creating a uniform look. They add a clean, finished touch to the sides without looking bulky or out of place.
These rock guards protect the paint from road debris. They’re tough enough to handle gravel and dirt while keeping the car looking flawless. The Hypersonic Gray paint stays smooth and chip-free, even on long drives. Walt’s choice shows his attention to detail. Small upgrades like this keep the car looking new for years.
