Mount Hella Horns on a Subaru Without Drilling or Fabricating
The GrimmSpeed Brotie Mounting Bracket for Hella Horns for the 2002-2021 Subaru WRX and STI is a direct bolt-on mounting solution for the popular Hella Supertone and similar dual-horn upgrades. The factory horn location on Subaru WRX and STI models is a single horn in a position that is not designed for dual Hella-style horn mounting — the GrimmSpeed bracket provides correct mounting geometry for two Hella horns at the factory horn location without modification to the bumper, radiator support, or wiring.
Correct Mounting Without Modification
Hella Supertone horn installations on Subaru WRX and STI models frequently use zip ties, fabricated brackets, or uncomfortable compromises in horn positioning. The GrimmSpeed bracket is purpose-designed for this application — the mounting geometry is correct for the Hella horn dimensions and the bracket bolts to existing Subaru chassis mounting points. Both horns mount at the correct angle and position for proper sound projection.
Pairs With GrimmSpeed Wiring Harness for a Complete Installation
For a complete Hella horn installation on a Subaru WRX or STI, the GrimmSpeed bracket pairs with the GrimmSpeed Wiring Harness for Hella Horns (GRM040005) — the wiring harness provides a plug-and-play electrical connection for the Hella horns that integrates with the factory horn wiring without cutting or splicing. Together the bracket and harness provide a complete, clean Hella horn installation.
