When it comes to wiring the Hella Horns that are mounted to your beautiful GrimmSpeed BroTie, we have you covered. After some testing, we determined that the additional few dBs offered by wiring with a relay weren't worth the added headache and potential failure points of a more complex harness using automotive relay, inline fuse and additional wiring directly to your battery. Fully pre-assembled, our simple harness will allow you to plug and play in seconds. Should your heart desire those last few ounces of ear-piercing goodness, our harness can also be adapted for use with a more complex relay harness. Diagrams for that configuration are included in our installation guide below.

In GrimmSpeed's opinion, the OEM Subaru crank pulley has been a cause for concern ever since its original design. It is relatively heavy, susceptible to catastrophic failure, and quite unsightly. Continuing to use this on cars just wouldn't do. Eliminating rotational mass while maintaining a safe presence can increase reliability and bring faster Rev's! For this Lightweight Crank Pulley GrimmSpeed pulled out all of the stops. CNC machined from 6061 T6 Aluminum this pulley makes no compromise. It weighs in at 3.5lbs lighter than OEM while at the same time increasing its durability. Marked with a timing mark and perfect cut keyway makes this install a breeze. GrimmSpeed designed the pulley with the optimum weight for performance while avoiding misfire CEL's and engine hesitation.
