Do ZL1 Addons products require drilling?

What is a wicker bill and does it actually add downforce?

A wicker bill (also called a Gurney flap) is a small lip that attaches to the trailing edge of your rear spoiler. It increases the effective angle of the spoiler , generating additional rear downforce without the drag penalty of a larger wing. ZL1 Addons wicker bills are available in multiple sizes and materials � from standard Lexan to full carbon fiber.

What material should I choose for my ZL1 Addons splitter?

HDPE (3/8" thick) is the most popular choice � it is extremely durable, flexible enough to absorb impacts from speed bumps and road debris, and will not crack or shatter. For show car builds or weight-sensitive track cars, carbon fiber offers a premium finish and lighter weight at a higher price point.

Will a front splitter scrape on speed bumps?

If your car is lowered, some scraping is possible. ZL1 Addons designed their splitter guard washers specifically for this � stainless steel washers with a 45-degree bevel that glide over road surfaces instead of catching. Pairing a splitter with guard washers is the recommended setup for street-driven cars.
