The Impreza WRX Grounding kit
The standard grounding kit is built with high grade 8ga wire. Includes standard or upgrade ring terminals, color matched shrink tubing (except dark blue which uses black), color matched zip ties.
The upgrade kit changes out all standard ring terminals with nice gold ends.
The super upgrade kit adds fully soldered ends to the kit, for super low resistance.
