Rear Wing Installation Kit

The Rear Wing Installation Kit is a universal solution for securely mounting rear wings or spoilers to a variety of bootlids/trunks – particularly suited to BMW models, but compatible with other platforms as well.

Designed to reduce stress on the outer boot skin under high-speed load and downforce, this kit ensures a robust and reliable installation for motorsport or fast-road use.

Fitment Notes

This is a universal kit – bootlid construction varies by model, so fitment may differ depending on the depth and layout of the inner skin.

Now available in two lengths to suit different bootlid designs:

• 35mm length – for standard or shallow inner skins

• 65mm length – for deeper inner skins (common on some BMW models)

What's Included

✔ 2 x Stainless Steel Cups (choose 35mm or 65mm length)
✔ 2 x Large 46mm Washers

⚠ Note: Kit is sold as a pair. If you require 4 cups for your installation, simply order two kits.

Materials & Installation Options

Manufactured in stainless steel, these cups can be:

• Welded directly to the boot skin for maximum strength (steel bootlids only)

• Chemically bonded using structural adhesives for carbon fibre or composite bootlids

🔧 Welding is not required for most installations – bonding is sufficient in many applications.
