Overview

This kit pairs the GrimmSpeed BroTie horn bracket with a set of Hella Supertone horns for 2002-2021 Subaru WRX and 2004-2021 STI, plus many Impreza, Forester, Legacy and Outback models. The wiring harness is not included, so you can wire the horns your own way or add a GrimmSpeed plug-and-play harness.

GrimmSpeed engineers overlaid 3D scans of the GD, GR and VA chassis core supports in CAD to create one bracket that works across all supported models, so it can move with you to your next car. Three long mounting slots on each side let you mount the horns wide, tight, high, low or anywhere in between to suit your grille. Heavy 1/8 in. steel and black powdercoat keep the horns secure and protected.
