Have you ever thought to yourself, "Man, Trent, you've got all of these awesome parts but how are you supposed to let your crew know you're coming?" Well, we're proud to introduce to you the GrimmSpeed BroTie mounting bracket for Hella Horns and other accessories.

Our engineers overlaid 3D scans of GD, GR and VA chassis core support in CAD. From there, a unique design was created that allows the same bracket to work on all supported models. This means that should to change cars, your BroTie can stay by your side. Also incorporated are three long mounting slots on each side, for maximum adjustability. This allows you to place the horns in a number of different configurations, depending on your grill and personal preference.

When it comes to wiring, we also have you covered. After some testing, we determined that the additional few decibels offered by wiring with a relay weren't worth the added headache and potential failure points of a more complex harness. Pre-assembled, our simple harness will allow you to plug and play in seconds.

Solid horn mount.

I purchased this to put on my 2017 Forester with some Hella Sharptones. It is a very sturdy mount. I really like that it is designed so that you can mount the horns in three different channels and at varying distances apart. The only issue that I had was that I could only use one bolt to fasten it to the vehicle, only because two bolts is better than one. This is a personal issue since it bolted up solid to the vehicle.
